Explanation:
Answer:
BRANILIST PLZ..
Explanation:
The unbalanced redox equation is as follows:
CuO+NH
3
→Cu+N
2
+H
2
O
Balance all atoms other than H and O.
CuO+2NH
3
→Cu+N
2
+H
2
O
The oxidation number of Cu changes from 2 to 0. The change in the oxidation number of Cu is 2.
The oxidation number of N changes from -3 to 0. The change in the oxidation number of one atom of N is 3. For 2 N atoms, the total change is 6.
The increase in the oxidation number is balanced with decrease in the oxidation number by multiplying CuO and Cu with 3.
3CuO+2NH
3
→3Cu+N
2
+H
2
O
O atoms are balanced by adding 2 water molecule on RHS.
3CuO+2NH
3
→3Cu+N
2
+3H
2
O
H atoms are balanced.
This is the balanced chemical equation.
