Question

Write a balanced equation for the following, including physical states: Magnesium + Hydrochloric Acid > Magnesiumchloride + Hydrogen gas Mg + HCl > MgCl + H Is that it? I feel like I'm missing something.

Answer 1

`Mg_((s)) +2HCl_((aq)) rarr MgCl_(2(aq))+ H_(2(g)) uarr`

Explanation:

Some small details you missed are that magnesium chloride is `MgCl_2` and that hydrogen gas is `H_2`.

So it should be:

`Mg_((s)) + HCl_((aq)) rarr MgCl_(2(aq)) + H_(2(g)) uarr`

When you balance it, it will become:

`Mg_((s)) + 2HCl_((aq)) rarr MgCl_(2(aq)) + H_(2(g)) uarr`
