Question

What happens when egg shells is added to nitric acid.​

Answer 1

Answer:Formation of Calcium Nitrate, Carbon Dioxide, Water

Explanation:Since egg shell is made of calcium carbonate. And we know that when calcium carbonate (CaCO3) reacts with Nitric acid (HNO3) then carbon dioxide, calcium nitrate and water are formed. So same reaction happens when Nitric acid is added to an eggshell.

Chemical equation for reaction of nitric acid with egg shell :-

CaCO3 + 2HNO3→ Ca(NO3)2 + CO2 + H2O

Answer 2

Answer:

• CaCO3(egg shell) + 2HNO3(nitric acid) ----} Ca(NO3)2 + CO2(g) + H20(l)

Explanation:

• Here, didplacement reaction occured.
• Also you need to know that egg shell is made of calcium carbonate.
• And on reacting with nitric acid it yields calcium nitrate along with water and carbon dioxide.
