its your answer hope this helps you

Answer 2

Answer:

Explanation:

1.The alkali metals (Li, Na, K, Rb, Cs, and Fr) are the most reactive metals in the periodic table - they all react vigorously or even explosively with cold water, resulting in the displacement of hydrogen

2.Metals react with water and produce a metal oxide and hydrogen gas. ... It reacts with hot water to form magnesium hydroxide and hydrogen. It also starts floating due to the bubbles of hydrogen gas sticking to its surface. Metals like aluminium, iron and zinc do not react either with cold or hot water.

3.The metals which react with cold water are; sodium, calcium and potassium.

4.All the alkali metals react vigorously with cold water. In each reaction, hydrogen gas is given off and the metal hydroxide is produced.
