What reaction might we use to synthesize nickel sulfate, NiSO4?

Chemistry

As I understand from your question, we should synthesize nickel sulfate first from nickel (II) oxide and sulfuric acid and second from nickel carbonate and sulfuric acid.

The chemical reactions will look like this:

NiO (s) + H₂SO₄ (aq) → NiSO₄ (aq) + H₂O (l)

NiCO₃ (aq)* + H₂SO₄ → NiSO₄ (aq) + H₂CO₃ (aq)

but carbonic acid will decompose to carbon dioxide and water

H₂CO₃ (aq) → CO₂ (g) + H₂O (l)

(*) NiCO₃ has a poor solubility in water, but enough to start the reaction.

8CO + 17H2 → C8H18 + 8H2O
liq [111]

Answer: 27,625 grams

Explanation:

*This is actually pretty simple

According to your equation, we know that:

8 moles of CO will react completely with 17 moles of H2

so:

6.50 moles of Co will react completely with x moles of H2

x= (6.50 x 17)/8 = 13.8125 (moles)

Since the Molar Mass of H2 is 2 g/mol, we can calculate the amount of H2 needed to react completely with 6.50 moles of CO:

=>13.8125 x 2= 27.625 (grams)
