What does the Law of Conservation of Mass state?
The Law of Conservation of Mass states that matter cannot be created or destroyed in a chemical reaction, only rearranged.
What is stoichiometry used for in chemical reactions?
Stoichiometry is used to calculate the amounts of reactants and products in a chemical reaction.
What is the molar ratio in a balanced chemical equation?
The molar ratio is the ratio of the coefficients of the reactants and products in a balanced chemical equation, used to relate the amounts of substances involved.
What is the limiting reagent in a chemical reaction?
The limiting reagent is the reactant that is completely consumed in the reaction, determining the maximum amount of product that can be formed.
What is the mole concept used for in stoichiometry?
The mole concept allows chemists to relate the macroscopic amounts of substances (grams, liters) to the number of particles (atoms, molecules) involved in a reaction.
What is the purpose of balancing a chemical equation?
Balancing a chemical equation ensures that the Law of Conservation of Mass is followed, with the same number of atoms of each element on both sides of the equation.

What is a combustion reaction?
A combustion reaction occurs when a substance reacts with oxygen to produce heat and light, typically producing carbon dioxide and water.
What is the difference between empirical and molecular formulas?
An empirical formula shows the simplest whole number ratio of elements in a compound, while a molecular formula shows the actual number of atoms of each element in a molecule.
What is the significance of stoichiometry in determining the yield of a reaction?
Stoichiometry helps predict the amounts of products and reactants involved in a reaction, enabling the calculation of theoretical yield and comparison with actual yield.
