Question

1. which of the following is true of a limiting reagent? select two answers.

options:

• it is a reactant
• it limits the amount of product formed
• it determines the minimum amount of pro...
• it does not affect the product formed
• it does not affect the reaction.

Explanation:

1. A limiting reagent is a reactant in a chemical reaction. So "It is a reactant" is correct.
2. The limiting reagent is the reactant that gets completely consumed first and thus limits the amount of product that can be formed. So "It limits the amount of product formed" is correct.
3. "It determines the minimum amount of product" is incorrect as it determines the maximum amount of product (since it runs out first).
4. "It does not affect the product formed" is incorrect as it directly affects the product amount.
5. "It does not affect the reaction" is incorrect as it is crucial for determining the reaction's outcome.

Answer:

A. It is a reactant, B. It limits the amount of product formed
