Predict the products of hydrobromic acid, H B r , reacting with magnesium hydroxide, M g ( O H ) 2 . Select one or more:
Aliun [14]

Answer:

Magnesium bromide, MgBr2, and water, H2O.

Explanation:

Hello!

In this case, since HBr is an acid and Mg(OH)2 is a base, an acid-base reaction is undergone, by which a salt and water are produced as neutralization products:

HBr+Mg(OH)_2\rightarrow MgBr_2+H_2O

However, it need to be balanced since two bromine atoms are produced, therefore we write:

2HBr+Mg(OH)_2\rightarrow MgBr_2+2H_2O

Thus, the products are magnesium bromide, MgBr2, and water, H2O.

Best regards!
