Question

01 question (4 points) a 0.301 g piece of solid magnesium reacts with gaseous oxygen from the atmosphere to form solid magnesium oxide. in the laboratory a student weighs the mass of the magnesium oxide collected from this reaction as 0.309 g. 1st attempt part 1 (1 point) the 0.301 g solid magnesium is the: choose one: a. excess reagent. b. percent yield. c. actual yield. d. theoretical yield. e. limiting reagent. part 2 (1 point) the 0.309 g magnesium oxide is the:

Explanation:

• In a chemical reaction, the limiting reagent is the reactant that gets completely consumed first and determines the amount of product formed. Here, the given mass of magnesium is a reactant. Since no information about oxygen quantity is provided and magnesium is a reactant, it is the limiting reagent.
• The actual yield is the amount of product actually obtained in a chemical reaction. The 0.309 g of magnesium oxide is what the student collected in the lab, so it is the actual yield.

Answer:

Part 1: E. limiting reagent
Part 2: C. actual yield
