Write a word equation for the reaction.

Write a correct formula for each reactant and product. We calculate moles with 22. Stoichiometry is founded on the law of conservation of mass where the total mass of the reactants equals the total mass of the products, leading to the insight that the relations among quantities of reactants and products typically form a ratio of positive integers. Everyone should have an “A” at the end of the first week. Identify each reactant and product. •If the numbers are not whole numbers, multiply by some factor to make them whole. carbon tetrabromide b.
