Yes it does react. It forms Calcium hydroxide and makes the water hot. It is because the reaction between CaO and water is an exothermic reaction

Which was does not react with cold water Ca or Mg or Sr or Ba?

Mg does not react with cold water while Ca, Sr, and Ba react with cold water to form metal hydroxide and hydrogen gas.


Why aluminum does not react with cold water?

Aluminum forms a protective oxide layer on its surface when exposed to air or water, which prevents further reaction with water. This oxide layer acts as a barrier, preventing the aluminum underneath from reacting with water. Additionally, aluminum is relatively low on the reactivity series, so it does not readily react with water, especially at cold temperatures.


Will there be a reaction between zinc and water?

Zinc reacts with steam to form Zinc oxide(yellow when hot and white when cold) and hydrogen. Zn+H2O=ZnO +H2


Does magnesium react?

Magnesium reacts with steam faster than cold water because magnesium needs to burn to get magnesium oxide and to get magnesium oxide there has to be heat and since steam is already heated it doesn't need much time, but the cold water needs time to heat first to react.


Does iron react in cold water?

Iron will slowly rust in cold water.


Why does zinc react with steam and not cold water?

Zinc does react with cold water - it just does so very slowly. Steam is water that is very hot and thus as with any chemical reaction, the heat gives the molecules more energy and so they react faster.


Which metals react slowly with cold water but vigorously with steam?

All metals, if they do react with water at all, react faster in steam than in water. However, the metals that react SLOWLY with cold water are the metals from Group-IIA(Magnesium, Calcium, etc).


Is does not react with cold water is a physical property?

A reaction with water (hot or cold) is a chemical reaction.
