Question

calcium with water. why does calcium start flowing in water?​

Answer 1

Answer:

The reaction of calcium with water is less violent. ... Calcium starts floating because the bubbles of hydrogen gas which are formed during the reaction stick to the surface of the metal and hence calcium floats on water.

Answer 2

Answer:

The bubbles formed stick to the surface of calcium metal and make it lighter. Therefore, Calcium floats on water. Note: Since the reaction of calcium and water is less violent, the heat released is less. Hence, hydrogen does not catch fire
