Reactions of metals when heated in air ; Metals below copper in the reactivity series ; Feedback. Note: As a general rule, if a metal reacts with cold water, you get the metal hydroxide. Metal are Cu, Hg, Ag, Pt and Au. Name one metal that will not react with cold water but will react with steam. Zinc reacts with steam to give zinc oxide and hydrogen gas. Chemistry Practical #Sabaqpk #sabaqfoundation #freevideolectures For example, magnesium reacts slowly with cold water. The Facts. Reaction of Metals. The reaction forms the metal oxide and hydrogen gas. We can observe the reaction of metals and water by placing the metals in a trough of cold water. D. Magnesium.

Class 3\r5. Practice tests and free video lectures for Physics, Chemistry, Biology, Math’s, Computer Science, English \u0026 more subjects are also available at Sabaq.pk. Metals that react slowly with cold water can react quickly with steam. To prevent its reaction with the moisture and other gases of air,sodium metal is always stored under kerosene. magnesium + steam magnesium oxide + hydrogen. Reaction of Aluminum Powders with Liquid Water and Steam. Join now. Metals from calcium upwards. Reaction of Flowing Steam with Refractory Metals III. Wiki User Answered . Potassium, sodium, lithium and calcium react with cold water, see alkali metals and alkaline earth metals. Answered Write the reactions of metals which reacts with steam. ← Prev Question Next Question → 0 votes . The reactivity of the metal determines which reactions the metal participates in.
