WILL GIVE THE BRAIN THING- Complete the following single replacement reaction.

Al(s) + HNO3(aq)

What are the products before balancing

The products are Al(NO₃)₃(aq) and H₂(g).

Al(s) + 3 HNO₃(aq) ⇒ Al(NO₃)₃(aq) + 1.5 H₂(g)

Explanation:

Let's consider the reaction between aluminum and nitric acid. This is a single replacement reaction, in which Al replaces H in HNO₃ to form aluminum nitrate. The unbalanced reaction is:

Al(s) + HNO₃(aq) ⇒ Al(NO₃)₃(aq) + H₂(g)

We start balancing N atoms by multiplying HNO₃ by 3.

Al(s) + 3 HNO₃(aq) ⇒ Al(NO₃)₃(aq) + H₂(g)

Finally, we get the balanced equation multiplying H₂ by 1.5.

Al(s) + 3 HNO₃(aq) ⇒ Al(NO₃)₃(aq) + 1.5 H₂(g)
