Answer 1

Answer:

yes all the statement r absolutely correct i have read it in my textbook absolutely sure answer is D)all the above statements are correct

Answer 2

All of the above statements are correct. (Option D)

• Calcium carbonate does react with dilute hydrochloric acid,in order to form calcium chloride,water and carbon dioxide gas. So, the first statement is true.

CaCO3 + HCl (dil.) ---> CaCl2 + H2O + CO2

• Limewater or calcium hydroxide solution is colourless but when we pass carbon dioxide gas through it, the white coloured calcium carbonate is formed. That's why, the limewater turns milky.

Ca(OH)2 + CO2 ---> CaCO3 + H2O

• Yes, limestone and marble are two different forms of calcium carbonate.
