उत्तर

On burning, sodium metal combines with oxygen in the air to form sodium oxide.

\[\ce{\underset{\text{Sodium}}{4Na_{(s)}} + \underset{\text{Oxygen}}{O_{2(g)}} -> \underset{\text{Sodium oxide}}{2Na2O_{(s)}}}\]

Which among the following statements is incorrect for magnesium metal?


Three metal samples of magnesium, aluminium and iron were taken and rubbed with sandpaper. These samples were then put separately in test tubes containing dilute hydrochloric acid. Thermometers were also suspended in each test tube so that their bulbs dipped in the acid. The rate of formation of bubbles was observed. The above activity was repeated with dilute nitric acid and the observations were recorded.

Answer the following questions:

(i) When the activity was done with dilute hydrochloric acid, then in which one of the test tubes was the rate of formation of bubbles the fastest and the thermometer showed the highest temperature?

(ii) Which metal did not react with dilute hydrochloric acid? Give reason.

(iii) Why is hydrogen gas not evolved when a metal reacts with dilute nitric acid? Name the ultimate products formed in the reaction.

OR

Name the type of reaction on the basis of which the reactivity of metals is decided. You have two metals X and Y. How would you decide which is more reactive than the other?
