This problem is providing the chemical reaction whereby barium nitride reacts with water to produce barium hydroxide and ammonia, so the number of moles of barium nitride are required in order to produce 8.3 moles of ammonia. It asks for us to evaluate the student's setup, so we conclude the answer is C. "1 mol of NH3 should be replaced with 2 mol of NH3", according to:
<h3>Mole ratios:</h3>In chemistry, stoichiometric calculations are used to figure out the moles or mass of a substance, given information about another one in the reaction. In this case, for the given chemical equation:
We evidence a 1:2 mole ratio of barium nitride to ammonia, for that reason, the student's setup:
Is incorrect, because the ammonia must be accompanied by a 2 rather than the 1 it is given there:
Thereby, the correct answer is C. "1 mol of NH3 should be replaced with 2 mol of NH3"

Answer:Total energy gained by 15.71 g is 3090.6471 joules
Explanation:
Given:
Q = heat gained by the 15.71 gram mass of gold
c = specific heat capacity of gold = 0.1291
m = mass of gold =15.71 g
Heat gained by gold =
=3090.6471 joules
