Question

name two metals which react with cold water to form hydrogen. write the balanced chemical equation
Help please​

Answer 1

Sodium

When sodium is added to water, it melts to form a ball that moves around on the surface. It fizzes rapidly, and the hydrogen produced may burn with an orange flame before the sodium disappears.

Sodium + water → sodium hydroxide + hydrogen

2Na(s) + 2H2O(l) → 2NaOH(aq) + H2(g)

Potassium

When potassium is added to water, it melts and floats. It moves around very quickly on the surface of the water. The hydrogen ignites instantly. The metal is also set on fire, with sparks and a lilac flame. There is sometimes a small explosion at the end of the reaction.

Answer 2

Answer:

Copper and zinc reacted with cold water
