Stoichiometry is the branch of chemistry that deals with the calculation of reactants and products in chemical reactions based on the conservation of mass.
2.
FLASHCARD QUESTION
Front
Define a limiting reactant.
Back
A limiting reactant is the substance that is completely consumed in a chemical reaction, limiting the amount of product that can be formed.

FLASHCARD QUESTION
Front
What is the theoretical yield?
Back
The theoretical yield is the maximum amount of product that can be produced from a given amount of reactants, calculated based on stoichiometric ratios.

FLASHCARD QUESTION
Front
What is the difference between actual yield and theoretical yield?
Back
Actual yield is the amount of product actually obtained from a reaction, while theoretical yield is the calculated maximum amount based on stoichiometry.
