Explain why calcium metal after reacting with water starts floating on its surface. Write the chemical equation for the reaction. Name one more metal that starts floating after some time when immersed in water. [CBSE 2012]

The Reaction Of An Acid With A Metal | Reactions Of …

A possible extension is to hold a cold piece of metal or glass above the place where you burst the bubbles so that the water vapour that forms during the reaction condenses on the metal or glass. Place approximately 1 g of the magnesium pieces in the test tube, but do not add the hydrochloric acid until everything else is ready to be asseled.

Reacting Carbon Dioxide with Lime water | Superprof

CaCO3 +H20This means that the carbon dioxide and limewater react to produce calcium carbonate and water. Calcium carbonate is chalk, and when it is produced, it precipitates (i.e. solid particles of chalk appear). The appearance of this solid makes the liquid
