Question

Ni(OH)3 + HNO3 = Ni(NO3)2 +O2 + H2O

Answer 1

4Ni(OH)3 + 8 HNO3 = 4 Ni(NO3)2 + O2 + 10 H2O

Answer 2

Chemical Reaction:

The chemical reaction provided is: Ni(OH)3 + HNO3 = Ni(NO3)2 + O2 + H2O

This reaction involves the reaction between nickel(III) hydroxide and nitric acid to produce nickel(II) nitrate, oxygen, and water.

The balanced chemical equation for this reaction is: 2Ni(OH)3 + 6HNO3 = 2Ni(NO3)2 + 3O2 + 6H2O.

The reaction results in the formation of nickel(II) nitrate, oxygen gas, and water.

Explanation:

When nickel(III) hydroxide reacts with nitric acid, it forms nickel(II) nitrate, oxygen gas, and water. The balanced equation shows that 2 moles of nickel(III) hydroxide react with 6 moles of nitric acid to produce 2 moles of nickel(II) nitrate, 3 moles of oxygen gas, and 6 moles of water.

This reaction is a redox reaction, where nickel undergoes a change in oxidation state from +3 to +2, and nitrogen undergoes a change in oxidation state from +5 to +2.

The reaction is also an example of a double displacement reaction, where the cations and anions of two different compounds switch places to form two new compounds.

Conclusion:

The reaction of nickel(III) hydroxide with nitric acid results in the formation of nickel(II) nitrate, oxygen gas, and water, as shown in the balanced chemical equation: 2Ni(OH)3 + 6HNO3 = 2Ni(NO3)2 + 3O2 + 6H2O.
