Hydrogen gas is not evolved when Metal reacts with nitric Acid give reason

Payal Singh 8 years, 4 months ago

The reaction of calcium with water is less violent. SO, the heat released is not sufficient for the hydrogen to catch fire. Calcium starts floating because the bubbles of hydrogen gas which are formed during the reaction stick to the surface of the metal and hence caclium floats on water.
