Question

Please help

1. What do you know already about the reactions of metals with water, acids and with the air (oxygen)?

2.Is it unusual for a metal to react with cold water (H20) ?

3.Is it usual for a metal to react with dilute hydrochloric acid? If it is, what are the products of the reaction (think coursework ...
magnesium and hydrochloric acid)

4. Is it usual for a metal to react with air / oxygen? If it is, what type of product forms?

Answer 1

1: A salt plus hydrogen gas

2: Yes, the metals which react with cold water are; sodium, calcium and potassium. Magnesium does not react with cold water. Metals like aluminum, iron and zinc do not react either with cold or hot water. Metals such as lead, copper, silver and gold do not react with water at all.

3: There is no reaction between dilute hydrochloric acid or sulfuric acid and the metals below hydrogen in the reactivity series.

4: Yes. The product that forms is called rust.
