Question

How many mg of NO2 can be produced, and what is the limiting reactant?"

A) We need more information to determine the amount of NO2 produced.
B) The limiting reactant is not provided, so the amount of NO2 produced cannot be determined.
C) The limiting reactant is given, and the amount of NO2 produced can be calculated.
D) The amount of NO2 produced is 42 mg.

Answer 1

To find the limiting reactant for producing ammonia from nitrogen and hydrogen, masses must be converted to moles and compared based on the balanced chemical equation. The limiting reactant will dictate the maximum amount of ammonia that can be produced.

Step-by-step explanation:

To determine the limiting reactant and how many grams of ammonia (NH3) can be produced from reacting nitrogen with hydrogen, we apply the concept of stoichiometry using the balanced equation N2 + 3H2 → 2NH3. Given 6.2 grams of nitrogen and 6.2 grams of hydrogen, we must first convert these masses to moles based on their molar masses (Nitrogen: 28.02 g/mol, Hydrogen: 2.02 g/mol).

To find out which reactant is limiting, we compare the mole ratio of the reactants to the mole ratio in the balanced chemical equation. The reactant that is available in the lesser stoichiometric amount is the limiting reactant, which dictates the maximum amount of product that can be formed.

The amount of ammonia produced is determined by the moles of the limiting reactant and the stoichiometry of the reaction. If any other reactant remains in excess, it can also be calculated how much of it is left over after the reaction.
