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
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
Number of atoms present on product side are as follows.
- Al = 2
- Ni = 3
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 .
