Question

7.
Complete the following reactions
1. CaCO, + 2HCl(aq)
ii.
+ 2KOH) → K2CO3 + H2S​

Answer 1

Step-by-step explanation:

Complete the reactions

1. Calcium carbonate reacts with aqueous HCl to give CaCl2 and CO2 according to the reaction, CaCO3(s) + 2 HCl(aq) → CaCl2(aq) + CO2(g) + H2O.
2. Potassium hydroxide react with carbon dioxide to produce potassium carbonate and water. Potassium hydroxide - concentrated solutions.

2KOH + CO2 → K2CO3 + H2S

hope you got it. .....
