Answer: A balanced equation for the given reaction is .
Explanation:
The reaction equation will be as follows.
Number of atoms on the reactant side is as follows.
- O = 2
- C = 1
Number of atoms on the product side is as follows.
- Ni = 1
- O = 2
- C = 1
Since number of atoms on both the reactant and product sides are equal. Hence, the reaction equation is balanced.
Thus, we can conclude that a balanced equation for the given reaction is .
Answer : The balanced chemical equation is,
Explanation :
Rules for the balanced chemical equation in basic solution are :
- First we have to write into the two half-reactions.
- Now balance the main atoms in the reaction.
- Now balance the hydrogen and oxygen atoms on both the sides of the reaction.
- If the oxygen atoms are not balanced on both the sides then adding water molecules at that side where the more number of oxygen are present.
- If the hydrogen atoms are not balanced on both the sides then adding hydroxide ion
at that side where the less number of hydrogen are present.
- Now balance the charge.
The half reactions in the basic solution are :
Reduction : ......(1)
Oxidation : .......(2)
Now multiply the equation (1) by 2 and then added both equation, we get the balanced redox reaction.
The balanced chemical equation in a basic solution will be,
