WebMetals and Non-metals Class 10 Important Questions Very Short Answer Type. Question 1. Why does a metal not release H 2 gas on reacting with dilute nitric acid? Answer: As nitric acid acts as a strong oxidising agent and oxidises the released H 2 gas to H 2 O and itself is reduced to either of these gases – N 2 O, NO 2 or NO. Question 2. WebExothermic reactions of metals and acid and metal displacement reactions are experiments that learners can carry out themselves. These investigations may be spread over two or three lessons to make the content manageable. The displacement reactions are carried out in microscale using a spotting tile.
