Question

Identify the neutralization reaction. 2NH3 + H2SO4 ⟶ (NH4)2SO4 2H3PO4 + 3Ba(OH)2 ⟶ 6H2O + Ba(PO4)2 2 NO2 ⟶ 2 O2 + N2 PO4 3Pb + 2H3PO4 ⟶ 3H2 + Pb3(PO4)2

Answer 1

There are two neutralization reactions.

2NH3 + H2SO4 ⟶ (NH4)2SO4

base acid salt

2H3PO4 + 3Ba(OH)2 ⟶ 6H2O + Ba(PO4)2

acid base salt

Answer 2

`2H_3PO_4 + 3Ba(OH)_2 \rightarrow 6H_2O + Ba_3(PO4)_2`

Step-by-step explanation:

Hello,

In this case, it is necessary to remember that a neutralization chemical reaction occurs when an acid reacts with a hydroxide to yield a salt and water. In such a way, the only reaction matching that definition is:

`2H_3PO_4 + 3Ba(OH)_2 \rightarrow 6H_2O + Ba_3(PO4)_2`

As phosphoric acid reacts with barium hydroxide to yield a neutral salt, barium phosphate and water.

Regards.
