(chemistry) the relation between the quantities of substances that take part in a reaction or form a compound (typically a ratio of whole integers) Choose matching term Limiting Reactant Actual Yield Stoichiometry Theoretical Yield

## Step 1<br />The problem is asking us to identify the term that best describes the relationship between the quantities of substances that participate in a chemical reaction or form a compound. The options provided are: Limiting Reactant, Actual Yield, Stoichiometry, and Theoretical Yield.<br /><br />## Step 2<br />Let's analyze each option:<br />- Limiting Reactant: This is the reactant that is completely consumed in a chemical reaction. It determines the maximum amount of product that can be formed.<br />- Actual Yield: This is the amount of product that is actually formed when the reaction is carried out in an experiment.<br />- Stoichiometry: This is the calculation of reactants and products in chemical reactions in terms of the amount of substance (in moles).<br />- Theoretical Yield: This is the amount of product that would be formed if the reaction were 100% efficient.<br /><br />## Step 3<br />From the above definitions, it is clear that the term that best describes the relationship between the quantities of substances that participate in a chemical reaction or form a compound is Stoichiometry. This is because stoichiometry involves the calculation of reactants and products in chemical reactions in terms of the amount of substance (in moles), which is exactly what the problem is asking for.
