Free PDF Download of CBSE Class 10 Science Chapter 3 Metals and Non-Metals Multiple Choice Questions with Answers. + Water-reactive substances are those that spontaneously undergo a chemical reaction with water, as they are highly reducing in nature. why metal do not react with water. Usually, non-metals do not react with water; but some non-metals react vigorously with air. So, as soon as hydrogen gas is formed in the reaction between a metal and dilute nitric acid, the nitric acid oxidisesthis hydrogen to water. Alkali Metals A common characteristic of most Alkali metals is their ability to displace H2(g) from water. Metals like aluminium, zinc, iron do not react with hot/cold water ; they react only with steam to form a metal oxide and hydrogen . 3. 1 decade ago.
