b. Why is it necessary to balance chemical equations and how can one verify that a chemical equation is properly balanced? How do you balance chemical equations? Explain using the following example. AsH3 arrow As + H2 Why do chemical equations need to be balanced? Explain briefly. How do...
TheLaw of Conversation of Massstates that atoms are neither created nor destroyed during a chemical reaction. As a result, the total number of atoms of each type must always be the same on either side of the chemical equation. Since the reactants and the products do not change, often the...
What is a chemical reaction and what are some examples? How do you know if a chemical reaction will occur? How do you write a chemical equation with no reaction? How does mass change during a chemical reaction? What happens to the reactants in a chemical reaction?
One of the most fundamental concepts that you need to learn in chemistry is how to write a chemical equation. Chemical equations are used whenever a compound is formed or decomposed. This is why learning how to write them is so crucial since most of chemistry is based around the formation a...

Look at the formula for a chemical reaction and ask yourself a series of questions. Do you see any of the “giveaways” you listed? Does the reaction involve two or more chemicals to make one compound? If so, then it’s a synthesis reaction. Does your reaction follow the formula AB +...
