Al(s) + HCl(aq)->AlCl3(aq) + H2(8) What type of reaction is this

Chemistry
1 answer:
weeeeeb [17]3 years ago
4 0

Answer:

Single Displacement

Explanation:

Single displacement occurs when a new element replaces one of the atoms in a group.

The skeleton formula for this is:

AB + C => AC + B

The "new" element, C, replaces B in the reaction.

In the equation for this equation, Al (aluminum) replaces H (hydrogen) because in the right side, products, Al is with Cl.
