# Can you slove this whole question for me

There both positive numbers so they can be added~9

Step-by-step explanation:

Answer : The balanced chemical equation will be:

(i)

(ii)

Explanation :

Balanced chemical equation : It is defined as the equation in which total number of individual atoms on the reactant side is equal to the total number of individual atoms on product side.

Part (i):

The balanced chemical equation will be:

This reaction is a single displacement reaction in which most reactive element (potassium) displaces the least reactive element (hydrogen) form their solution.

Part (ii):

The balanced chemical equation will be:

This reaction is a single displacement reaction in which most reactive element (zinc) displaces the least reactive element (magnesium) form their solution.

Step-by-step explanation:

So we have the equation:

First, distribute the -3:

Combine like terms on the left:

Subtract 21 from both sides:

Divide both sides by -5:

So, the value of y is -11.

And we're done!
