Does calcium react with cold water, hot water or steam? Why?
Dear student
Calcium reacts with cold water to form calcium hydroxide and hydrogen gas which bubbles up and stick to the surface of calcium metal making it light, due to which calcium floats on water.
Ca(s) + 2H2O(l) → Ca(OH) 2 (aq) + H2 (g)
