Answer: The coefficient we should change first is for 
.
Explanation:
The given reaction equation is as follows.
Here, number of atoms present on reactant side are as follows.
- Al = 1
- Ni = 1
- = 2
Number of atoms present on the product side are as follows.
- Al = 1
- Ni = 1
- = 3
To balance this equation, multiply Al by 2 and by 3 on reactant side. Also, multiply 
by 2 and Ni by 3 on the product side.
Hence, the equation can be rewritten as follows.
Now, number of atoms present on reactant side are as follows.
- Al = 2
- Ni = 3
- = 6
Number of atoms present on product side are as follows.
- Al = 2
- Ni = 3
- = 6
Since, the atoms on both reactant and product side are same. Hence, it is now a balanced chemical equation.
Thus, we can conclude that the coefficient we should change first is for .
The production of ammonia (NH3) for fertilizer purposes, which supports about half of the world's population, is the artificial fixation of nitrogen (N2)'s significant energy, environmental, and societal consequence.
<h3>What is artificial fixation of nitrogen?</h3>
Through a chemical process known as nitrogen fixation, the air's molecular nitrogen (N2), which has a powerful triple covalent bond, is transformed into ammonia (NH).
Nitrogenous chemicals, commonly found in soil or aquatic systems but also in industry. Molecular dinitrogen, which makes up the majority of atmospheric nitrogen, is a generally nonreactive molecule that is biologically inert to most microbes. Utilizing the nitrogenase protein complex, biological nitrogen fixation, also known as diazotrophy, is a crucial microbially driven activity that turns dinitrogen (N2) gas into ammonia (NH3) (Nif).

Answer:
A reaction at equilibrium implies that the concentration/amount of reactants & products present in that reaction don't change but will remain constant. It could also mean that the forward reactions and reverse reactions will occur at the same rates.
