Homework Answers
The chemical formula basically gives us the information about the number of atoms which combines together by some chemical interaction to form a compound, and the balanced chemical equation gives us the information about the species combining together in the reaction to give a particular compound.
Example H2 + O2 -----> H2O2, So 1 mole of hydrogen gas combines with 1mole of oxygen gas to gives 1 mole of hydrogen peroxide

Why must chemical equations be balanced? In a balanced chemical equation, the coefficients in front of each reactant and product allow us to predict whether the given reaction is possible or not. In a balanced chemical equation, the coefficients in front of each reactant and product allow us to predict whether the reaction requires a catalyst or not. In a balanced chemical equation, the coefficients in front of each reactant and product allow us to predict the amount of product...
