Question

When BaCl2(aq) + Na2SO4(aq) are combined, there is a chemical reaction.

What do you conclude about the identity of one of the products?

Answer 1

BaCl

2

(aq)+Na

2

SO

4

(aq)→BaSO

4

(s)+2NaCl(aq)

The types of reactions are (b) Precipitation and (d) Double displacement.

A precipitate of bariumsulphate is obtained.

In double displacement reaction, two compounds react, and the positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products.

Answer 2

Explanation:

Answer

Correct option is

D

(b) & (d)

BaCl

2

(aq)+Na

2

SO

(s)+2NaCl(aq)

The types of reactions are (b) Precipitation and (d) Double displacement.

A precipitate of bariumsulphate is obtained.

In double displacement reaction, two compounds react, and the positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products.

So, the correct option is D.
