Answers
3CuO(s) + 2NH3(g) → 3Cu(s) + N2(g) + 3H2O(l).
3CuO(s) + 2NH3(g) → 3Cu(s) + N2(g) + 3H2O(l).Hence, oxidation state of the reactant atoms are as follows.
3CuO(s) + 2NH3(g) → 3Cu(s) + N2(g) + 3H2O(l).Hence, oxidation state of the reactant atoms are as follows.Cu = +2, O = -2, N = -3, H = +1
3CuO(s) + 2NH3(g) → 3Cu(s) + N2(g) + 3H2O(l).Hence, oxidation state of the reactant atoms are as follows.Cu = +2, O = -2, N = -3, H = +1Oxidation state of the product atoms are as follows.
3CuO(s) + 2NH3(g) → 3Cu(s) + N2(g) + 3H2O(l).Hence, oxidation state of the reactant atoms are as follows.Cu = +2, O = -2, N = -3, H = +1Oxidation state of the product atoms are as follows.Cu = 0, N2 = 0, H = +1, O = -2
3CuO(s) + 2NH3(g) → 3Cu(s) + N2(g) + 3H2O(l).Hence, oxidation state of the reactant atoms are as follows.Cu = +2, O = -2, N = -3, H = +1Oxidation state of the product atoms are as follows.Cu = 0, N2 = 0, H = +1, O = -2Therefore, balancing the given equation by oxidation method is as follows.
3CuO(s) + 2NH3(g) → 3Cu(s) + N2(g) + 3H2O(l).Hence, oxidation state of the reactant atoms are as follows.Cu = +2, O = -2, N = -3, H = +1Oxidation state of the product atoms are as follows.Cu = 0, N2 = 0, H = +1, O = -2Therefore, balancing the given equation by oxidation method is as follows.3CuO(s) + 2NH3(g) → 3Cu(s) + N2(g) + 3H2O(l).
Answer:
The unbalanced redox equation is as follows:
CuO + NH3 → Cu + N₂ + H₂O
Balance all atoms other than H and O. CuO + 2NH3 → Cu + N₂ + H₂O
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 + 2NH3 → 3Cu + N₂ + H₂O
O atoms are balanced by adding 2 water molecule on RHS.
3CuO + 2NH3 → 3Cu + N₂ + 3H₂O
Hatoms are balanced.
This is the balanced chemical equation.
