What is stoichiometry?
Stoichiometry is a branch of chemistry that deals with the calculation of reactants and products in chemical reactions based on the conservation of mass.
Which of the following represents the law of conservation of mass in a chemical equation?
A. The mass of the products exceeds the mass of the reactants.
B. The total mass of reactants equals the total mass of products.
C. Mass can be created or destroyed in a reaction.
D. Only gaseous elements are involved in mass calculations.
E. The mass of the solid produced is always less than the mass of the liquid.
