Predict the products of the electrolysis of molten nickel(II) iodide. Write an ionic half-equation for the formation of one of t
Daniel [21]

Answer:

See explanation

Explanation:

The electrolysis of  nickel(II) iodide yields nickel solid and iodine gas.

In the oxidation half equation;

2I^-(aq)-------> I2(g) + 2e

In the reduction half equation;

Ni^2+(aq) + 2e  -----> Ni(s)

These are the half equations of the process;

The  overall equation is;

Ni^2+(aq) + 2I^-(aq)-------> NiI2

a student balanced the chemical equation for the reaction of magnesium with oxygen by writing Mg + O2 ----> MgO2. What is wro
egoroff_w [7]

Answer:

Explanation:

Magnesium when it oxidizes has a valence of 2.

Oxygen, when it mixes with something, has a valence of - 2

So Mg and O2 will form something, but what? The answer is MgO

Mg + O2 ===> MgO

To balance this equation, you need 2 Magnesiums on the right and 2 Oxygens also on the right. The left will need a  two Magnesiums.

The balanced equation will be

2Mg + O2 ====> 2MgO
