How to Balance Chemical Equations 3 Simple Steps

How to Balance Chemical Equations 3 Simple Steps SAT / ACT Prep Online Guides and Tips A chemical equation tells you what happens during a chemical reaction. A balanced chemical equation has the correct number of reactants and products to satisfy the Law of Conservation of Mass. In this article, we’ll talk about what a chemical equation is, how to balance chemical equations, and give you some examples to aid in your balancing chemical equations practice. What Is a Chemical Equation? Simply put, a chemical equation tells you what’s happening in a chemical reaction. Here’s what a chemical equation looks like: Fe + O2 → Fe2O3 On the left side of the equation are the reactants. These are the materials that you start with in a chemical reaction. On the right side of the equation are the products. The products are the substances that are made as a result of a chemical reaction. In order for a chemical reaction to be correct, it needs to satisfy something called the Law of Conservation of Mass, which states that mass can’t be created or destroyed during a chemical reaction. That means that each side of the chemical equation needs to have the same amount of mass, because the amount of mass can’t be changed. If your chemical equation has different masses on the left and right side of the equation, you’ll need to balance your chemical equation. How to Balance Chemical Equations Balancing chemical equations means that you write the chemical equation correctly so that there is the same amount of mass on each side of the arrow. In this section, we’re going to explain how to balance a chemical equation by using a real life example, the chemical equation that occurs when iron rusts: Fe + O2 → Fe2O3 #1: Identify the Products and Reactants The first step in balancing a chemical equation is to identify your reactants and your products. Remember, your reactants are on the left side of your equation. The products are on the right side. For this equation, our reactants are Fe andO2. Our products areFe2 andO3. #2: Write the Number of Atoms Next, you need to determine how many atoms of each element are present on each side of the equation. You can do this by looking at the subscripts or the coefficients. If there is no subscript or coefficient present, then you just have one atom of something. Fe + O2→ Fe2O3 On the reactant side, we have one atom of iron and two atoms of oxygen. On the product side, we have two atoms of iron and three atoms of oxygen. When you write out the number of products, you can see that the equation isn’t balanced, because there are different amounts of each atom on the reactant side and the product side. That means we need to add coefficients to make this equation balanced. #3: Add Coefficients Earlier, I mentioned that there are two ways to tell how many atoms of a particular element exist in a chemical equation: by looking at the subscripts and looking at the coefficients. When you balance a chemical equation, you change coefficients. You never change subscripts. A coefficient is a whole number multiplier. To balance a chemical equation, you add these whole number multipliers (coefficients) to make sure that there are the same number of atoms on each side of the arrow. Here’s something important to remember about coefficients: they apply to every part of a product. For instance, take the chemical equation for water: H2O. If you added a coefficient to make it 2H2O, then the coefficient multiples across all of the elements present. So, 2H2O means that you have four atoms of hydrogen and two atoms of oxygen. You don’t just multiply against the first element present. So, in our chemical equation (Fe + O2→ Fe2O3), any coefficient you add to the product has to be reflected with the reactants. Let’s look at how to balance this chemical equation. On the product side, we have two atoms of iron and three atoms of oxygen. Let’s tackle iron first. When first looking at this chemical equation you might think that something like this works: 2Fe + O2→ Fe2O3 While that balances out the iron atoms (leaving two on each side), oxygen is still unbalanced. That means we need to keep looking. Taking iron first, we know that we’ll be working with a multiple of two, since there are two atoms of iron present on the product side. Knowing that using two as a coefficient won’t work, let’s try the next multiple of two: four. 4Fe + O2→ 2Fe2O3 That creates balance for iron by having four atoms on each side of the equation. Oxygen isn’t quite balanced yet, but on the product side we have six atoms of oxygen. Six is a multiple of two, so we can work with that on the reactant side, where two atoms of oxygen are present. That means that we can write our balanced chemical equation this way: 4Fe + 3O2→ 3Fe2O3 3 Great Sources of Balancing Chemical Equations Practice There are many places you can do balancing chemical equations practice online.

What are the main differences between imperfect competition and Outline

What are the main differences between imperfect competition and monopoly market structures - Outline Example It is a fact that monopolies are bad for the consumer market structures because they lead to an authoritative regime in place which can mean that there are no competitors and hence a great amount of one-man-rule that shall rule the roost in essence. What is most significant is the fact that monopolies and imperfect competition structures should be kept at a safe distance from the shores of any organization that wants to grow beyond its expectations. Also the consumers would be given the best possible space that they richly deserve and hence their predicaments would be taken care of, the sooner the better. Perfect competition remains a much desired for act that industries would always like to have within their ranks but this is hardly the case as there is a great amount of significance on having monopolies and imperfect competition market structures – the result of which are severe prices meted out on to the consumers with no possible alternatives in sight. Moving on with the d iscussion, imperfect competition is in direct negation with perfect competition because the latter makes sure that the end consumers are given the best possible return on their money and their shopping realms are safeguarded in such a manner that they believe in trying different products and services which are available to them. However what monopolies bring to the fore is nothing short of bad blood, where one organization believes in doing everything while the rest are just not present (Carlton 2005). The monopolistic competition demands a sense of responsibility on the part of the dominant and the sole player as it has to take steps which are essential for the up and coming firms and businesses and it must be kept in mind that the new companies are there to serve the customer better and in a new manner and the customers have every right to demand the very same. They cannot be denied their due right just because a dominant player is bent upon ruining other’s sales and increa sing its own in both the short term as well as the long run. A check and balance approach thus holds the key here and it is the responsibility of the government to control these measures, no matter how harsh the situations are and how stern the steps have to be taken. To quote as an example of monopolistic competition, Apple Inc was accused of having the same within its ranks. There was hue and cry that Apple Inc was forming a vertical monopoly with the signature DRM System, the iPod, iTunes and so on. The pricing strategies were largely decided by the organizational heads and thus the market levels were discouraged from booming in essence. Non-pricing strategies were not made use of by Apple Inc which also formed up as an essential ingredient of the kind of monopolistic competition that the organization was bent upon doing. Monopolistic competition does not usually last for long since governmental interventions and consumer insights get the better of such tyrannical levels of compe tition. There is a more advanced and up to date value-added mechanism in place with the advent of competing players which eventually throng the market and get the biggest share. Unquestionably, competition brings in expectations by the customers, end users and all those who depend a great deal on the said business. This is because competition has motivated them for so long now that the absence of competitive activity would mean a loss-loss exercise. This is generally an unacceptable phenomenon and needs to be taken care of by the people who matter the most within the helm of affairs in the organizational domains. Motivation will only take place when competition is sound enough to send shockwaves within the industrial domains and set the ball rolling as far as delivery of value and quality for the sake of end consumers is concerned. This means that motivation will act as a reinforcing agent once the

The con of the JIT relationship is that problems would occur if the company has sudden breaks to service and the supply. This may lead to labor strikes, and then eventually a failed business. A pro of the JIT relationship would be saving cost by not having unnecessary inventories. Also another attribute is flexibility, allowing the company to answer. †¢Analyze the short-term and long-term consequences that could come from implementing this JIT relationship. The short-term consequence of implementing JIT would be the cost that ties into the culture evolving, training staff on problem solving. The long-term consequence of JIT is improving the quality of the product along with the delivery of it. Once customers realize the proficiency of the company with its product that leads to a chance of a larger profit. †¢Discuss what factors Dixon and DS should consider before making a decision on this relationship. In regards to factors that Dixon and DS should consider before making a decision is: 1.Improved Quality- measuring the quality of service, timeliness, service consistency and courtesy. 2.Utilizing Multifunction Workers – Assist with improving quality and customer service. 3.Reduced Turn Around time – The competition is steady among companies that provide services, so a company that uses JIT concepts reduces the turnaround time and increase their speed.

Watergate Scandal and President Nixon Essay example -- American Preside

What kind of person commits three major violations of the national law and gets away with it? Well that person is Nixon. President Richard Nixon was one of the most famous presidents in the United States. He was mainly renowned for his huge role in the Watergate scandal. The Watergate scandal was important because Nixon and his cabinet arranged to get people to spy on the Democratic National Committee in the Watergate building. After it became clear Nixon was responsible, he manages to resign before he was going to be impeached. President Nixon was involved with the Watergate scandal and should be sentenced to jail because he organized it, which then got leaked out and finally led to his resignation. Nixon was the mastermind behind the mission and the main reason he organized it was to find out secret information of the Democrats. He organized a committee to help him ensure his victory in the elections. â€Å"The committee to reelect the President† (CRP) used unfair tactics to get what they wanted. They organized a group of thugs – â€Å"Plumbers† to sneak into the Watergate and plant listening devices. The plumbers, James W. McCord, Bernard Barker, Virgilio Gonzalez, Eugenio Martinez, and Frank Sturgis however, were caught by the police. Nixon didn’t want anyone to find out about the break in. He said shortly after the plumbers were caught "In all my years of public life, I have never obstructed justice. People have got to know whether or not their President is a crook. Well, I'm not a crook; I earned everything I've got." Nixon lied through his teeth just to get the public attention on something else. What he didn’t realize was that it was th e beginning of his demise. Although many Americans didn’t care about the little scene in the ... ...r’s mission, people got infuriated with the scandal, and he resigned to get away with his mistakes. He got impeached because he violated of constitutional oath, prevented, obstructed, and impeded administration of justice, and concealed those responsible of prison. He violated the constitutional oath because he did not serve his country the way he is supposed to. He obstructed, prevented and impeded administration of justice because lied that he was not responsible for the scandal. He concealed those responsible of prison because he didn’t tell the authorities who else was involved in the scandal. John Srica, Carl Woodward, and Bob Bernstein did an amazing job uncovering the scandal and who was behind it. Nixon should go to jail because everybody else who was responsible did. However, he escaped the wrath of jail because the next president, Gerald Ford pardoned him.

The Generation Of Offset Curves - 1052 Words

Introduction Metalworking is one of the oldest occupations of humankind. At the beginning of last century metalworking machine tools were invented and these were controlled by an operator who performed all the movements of the tool in order to obtain the final parts. Nowadays, metalworking using machine tools is one of the most important activities to support industries development and the most important of these industries is the automotive industry. The main purpose of this paper is to investigate the generation of offset curves, considering both naive approaches and more sophisticated approaches such as the Voronoi diagram. The paper starts by explaining some basic concepts of offset machining, insisting on the most important types of compensation. The next section includes a discussion on different ways of representing curves in a computer program, starting with two-dimensional curves and ending with non-uniform rational B-spline curves (NURBS). The basics of offset machining Definition 1.1 A Computer Numerical Control (CNC) machine is a machine tool that uses programmed commands (alphanumeric codes) to control its movements and functions. The applications of CNC machines include drill press, sheet-metal press, milling machine, laser, grinding, welding machine etc. The most fundamental operation that can be performed with a CNC machine is to remove all the material that lies within some boundary.
