Question

1)Cr2(SO4)3+Na3Po4 2)K2S+HCl

Answer 1

Cr2(SO4)3 + Na3PO4 = CrPO4 + 2 NaSO4 + NaCrSO4.

K2S + 2HCl = 2KCl + H2S .

 

Answer 2

It seems like you've provided two chemical reactions. Let's balance them:

1. Cr2(SO4)3 + 2Na3PO4 → 6Na2SO4 + CrPO4
2. K2S + 2HCl → 2KCl + H2S

Here's a breakdown of the balanced reactions:

1. Chromium (III) sulfate reacts with sodium phosphate to produce sodium sulfate and chromium (III) phosphate.

2. Potassium sulfide reacts with hydrochloric acid to produce potassium chloride and hydrogen sulfide gas.
