What happens when magnesium is burnt in air and the products X and Y are treated with water ? A. `{:(X, Y , P , Q) , (Mg O , Mg"(OH)"_(2) , Mg"(OH)"_(2) , N_(2)):}`B. `{:(X, Y , P , Q) , (Mg O , Mg_(3)N_(2) , Mg"(OH)"_(2) , NH_(3)):}`C. `{:(X, Y , P , Q) , (Mg O , Mg_(3)N_(2) , Mg"(OH)"_(2) , N_(2)):}`D. `{:(X, Y , P , Q) , (Mg O , MgCO_(3) , Mg"(OH)"_(2) , CO_(2)):}` |

Answer» Correct Answer - B Magnesium reacts with air to form oxide and nitride. On reaction with water the oxide gives hydroxide and nitride gives hydroxide and ammonia. `2Mg + O_(2) to underset((X)) (2MgO)` `3Mg +N_(2) to underset((Y)) (mg_(3)N_(2))` ` MgO+ H_(2)O to underset((P))(Mg(OH)_(2))` `Mg_(3) N_(2)+ H_(2)O to underset((P))(3Mg (OH)_(2))+ underset((Q))2NH_(3))` |
