Answer:
Hydrogen
Explanation:
First thing's first, we have to write out the balanced chemical equation for the reaction.
This is given as;
N2 + 3H2 --> 2NH3
From the stoichiometrey of the reaction;
Molar mass of N = 14
Molar mass of H = 1
(1 * (14 * 2)) = 28g of N2 reacts with (3 * (1 * 2)) = 6g of H2
This means that if there are equal mass of both Nitrogen and Hydrogen. We would run out of Hydrogen first. This means Hydrogen is our limiting reactant as it determines the amount of products that can be formed.
Answer:c
Explanation: it states that the atom is neutral, meaning the number of electrons and protons are the same. so if there are 13 electrons, there are 13 protons. And the mass number is neutrons plus protons. So 13+15 is 28
