Question

Which compound is correctly balanced by charge in the following reaction?

Na OH + Mg(SO4)2 + Mg(OH)2 + NaSo,

a. Sodium Hydroxide
b. Magnesium Sulfate
c.Sodium Sulfate
d.Magnesium Hydroxide
e. Ambulance​

Answer 1

Answer:A,D

Step-by-step explanation:

Option a:

Sodium has charge
`+1`

Hydroxide has charge
`-1`.

So,sodium hydroxide is balanced.

Option b:

Magnesium has charge
`+2`

Two sulphates has a charge of
`-2* 2=-4`.

So,magnesium sulphate is not balanced.

Option c:

Magnesium has charge
`+2`

Two hydroxides have a charge of
`2* -1=-2`.

So,magnesium hydroxide is balanced.

Option d:

Sodium has charge
`+1`

Sulphate has charge
`-2`.

So,sodium sulphate is not balanced.
