Answer 1

Answer:

the answer is carbon dioxide

Explanation:

carbon dioxide gas turns limewater milky .

Answer 2

Answer:

a) Carbon - dioxide turns lime water milky

MORE TO KNOW -

• Quick lime - Cao

• Slaked lime - Ca(oh)^2

• Calcium carbonate - Caco3

• Ca(OH)2(aq) + CO2(g) → CaCO3(s) + H2O

• Calcium hydroxide is called lime water

its formula is Ca( oh)^2

• when carbon - dioxide is added to ca( oh)2 it turns lime water milky

• Slaked lime or Calcium hydroxide is formed by adding water to (Cao) Quick lime and it is in the form of white suspension.

• Quick lime ( Cao) is formed by heating limestone ( Caco3) Strongly.

• It is a type of combination reaction and exothermic reaction.

• Uses - Caco3 is used in industries specially for manufacture of cement.
