Question

PLEASE HELP!! CHEMICAL EQUATIONS

Answer 1

Answer:

Mg(s) + 2NaF (aq) —> MgF₂ (aq) + 2Na(s)

Explanation:

Magnesium => Mg

Sodium fluoride => NaF

Magnesium fluoride => MgF₂

Sodium metal => Na

The equation can be written as:

Mg + NaF —> MgF₂ + Na

Thus, the above equation can be balance as illustrated below:

Mg + NaF —> MgF₂ + Na

There are 2 atoms of F on the right side and 1 atom on the left side. It can be balance by writing 2 before NaF as shown below:

Mg + 2NaF —> MgF₂ + Na

There are 2 atoms of Na on the left side and 1 atom on the right side. It can be balance by writing 2 before Na as shown below:

Mg + 2NaF —> MgF₂ + 2Na

Mg(s) + 2NaF (aq) —> MgF₂ (aq) + 2Na(s)

Now, the equation is balanced.
