Select 3 correct answer(s)
Question 2 options:

BaCl2 + K2CrO4


BaCl2 + AgNO3

Al2(SO4)3 + K2CrO4


BaCl2 + MgSO4


BaCl2 + KCl


Na2CrO4 + AgNO3

Answer 1

The chemical reactions that resulted in a white precipitate are Na2CrO4 + AgNO3, Al2(SO4)3 + Ba(NO3)2, and BaCl2 + AgNO3.

Step-by-step explanation:

A white precipitate is formed when a chemical reaction results in the formation of an insoluble salt. From the given options, the correct sets of chemical reactions that resulted in a white precipitate are:

1. Na2CrO4 + AgNO3
2. Al2(SO4)3 + Ba(NO3)2
3. BaCl2 + AgNO3

In these reactions, the formation of a white precipitate indicates the presence of an insoluble compound.

Answer 2

Na2CrO4 + AgNO3

Al2(SO4)3 + Ba(NO3)2

BaCl2 + K2CrO4
