Imagine having 20 pieces of bread and 10 pieces of ham. How many ham sandwiches can be made? This question is exactly what this topic is about. The world wants to know ‘’how much,” whether it is chemistry or daily activities in life, this question is answered by Stoichiometry. If you have 4 frames and 12 wheels, how many bikes can be made? This is also a concept of stoichometry. The principles of Stoichiometry can also be used while cooking. If you are almost out of a certain ingredient, you could use the concept of Stoichiometry to figure out how much of every other ingredient is needed. Another example is that, a farmer determining how much fertilizer should be used, figuring out how fast you should go to get somewhere in a given period of …show more content…
The reactants are those substances that changes during a chemical reaction while the products are those that are yield during a chemical reaction. If the chemical reaction is not balanced, we cannot derive the relationship between the products and reactants. So the first thing we should do when we see a chemical reaction is to balance it. How do we balance a chemical equation? Look at this scale; we can see that it is unbalanced wherein the right side weighs more than the left side. In order for us to make the two sides balanced, we need to put more mass on the left side to make both sides have the equal amount of mass. Just like a chemical equation, it should also be balanced on both sides. A chemical equation shows the substances that are involved in a chemical reaction, as mentioned above, the reactants (substances that react) and the products (substances that are produced). A chemical equation looks like this: Reactants …show more content…
5.) After balancing the chemical equation, recheck again if both sides have the same number of each type of atom on both sides of the balanced equation. Examples of Balancing a Chemical Equation 1.) N2 + H2 NH3 In this chemical reaction, the Nitrogen (N2) reacts with Hydrogen (H2), yielding ammonia (NH3). The Nitrogen and the Hydrogen are the reactants while the ammonia is the product. In this equation, you can see that the number of atoms in the reactant side and the product side are not equal. The equation is not balanced since there are 2 Nitrogen atoms and also 2 Hydrogen atoms in the reactant side. However, there are 1 Nitrogen atom and 3 Hydrogen atoms in the product side. We were able to determine the number of atoms by looking at their respective subscripts. The subscript of an element tells how much atom they consist. To balance the chemical equation above, we will follow the 5 steps mentioned above. I. The elements found in the equation are Nitrogen and Hydrogen. II. There are 2 atoms of Nitrogen and 2 atoms of Hydrogen in the reactant side. There are only 1 Nitrogen atom and 3 Hydrogen Atoms in the product
