Zinc, Zn. Reaction with water. Zinc virtually has no reaction with cold water. Zinc reacts with steam to give zinc oxide and hydrogen gas. The reaction occurs in a similar way as magnesium does, but less vigorous.Reaction with oxygen. Strong heating is required to make zinc powder burn in oxygen. Much heat is given out during the reaction and a white powder is formed, which is yellow when hot and white when cold.he reaction occurs in a similar way as magnesium does, but less vigorous.
