Question

What is dry ice? What is it used for ?​

Answer 1

Answer:

Dry ice is the solid form of carbon dioxide. It is used primarily as a cooling agent, but is also used in fog machines at theatres for dramatic effects. Its advantages include lower temperature than that of water ice and not leaving any residue (other than incidental frost from moisture in the atmosphere)

Answer 2

Explanation:

When dilute sulphuric acid is added to sodium carbonate, the corresponding salt, sodium sulphate and water are formed and carbon dioxide gas is evolved.

H2SO4 + Na2CO3 → Na2SO4 + H2O + CO2
