According to law of conservation of mass.
In a chemical reaction Mass is neither created nor destroyed.
- Mass of product =Mass of reactant
#1
Mass of water

#2
Mass of sulphur:-

Entropy Change is the measure of the randomness of the thermodynamic system. The entropy change for the reaction is -49.3 J/K.
<h3>What is the change in entropy?</h3>
Entropy change is the ratio of the heat transfer of the system to the absolute temperature of the system.
The entropy of nickel = 182.1 J/mol. K
The entropy of oxygen = 205.0 J/mol. K
The entropy of nickel oxide = 37.99 J/mol. K
Entropy change is calculated as:

Therefore, -49.3 J/K is the entropy change.

Answer:
nitrogen
Explanation:
The stoichiometry of the reaction says that
and
react 3:1 to form 2 moles of
, so, if you have 3,5 moles of H, which is equal to 1,75 moles of
, and 5 moles of N, which are equal to 2,5 moles of
. only
=0.583 moles of
, will react, leaving <em>1.917 moles of </em>
<em>unreacted</em>, and forming 0.583*2=1.166 moles of
