what is the balanced equation for when an aqueous solution of hydrochloric acid reacts with sodium metal, aqueous sodium chlorin
FinnZ [79.3K]

Answer:

2Na(s) + 2HCl(aq) —> 2NaCl(aq) + H2(g)

Explanation:

Na(s) + HCl(aq) —> NaCl(aq) + H2(g)

Writing an ionic equation will actually help us to understand the equation and also to balance it. This is illustrated below:

Na + H+Cl-

Na is higher than H in the activity series and as such, it will displaces H from the solution and form NaCl with H2 liberated as shown below

Na + H+Cl- —> Na+Cl- + H2

Now, put 2 in front of Na, H+Cl- and Na+Cl- to balance the equation as shown below:

2Na + 2H+Cl- —> 2Na+Cl- + H2

Now we can write the elemental equation as follow:

2Na(s) + 2HCl(aq) —> 2NaCl(aq) + H2(g)
