Combine the following ions to create neutral compounds Y3+ and OH-

Y(OH)₃

Explanation:

Given ions:

                  Y³⁺      OH⁻

To find a neutral compound that conforms with the formation of the given ions;

We us the exchange of valency approach to solve this problem. The valency will form the combining power of the ions for the combination.

                                    Y³⁺      OH⁻

Combining power        3           1

Exchange of valency    1            3

 Now the compound is        Y(OH)₃

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.
