Grade 12th pass10 grade science
A magnesium ribbon is burnt in oxygen to give a white compound ‘X’ accompanied by emission of light. If the burning ribbon is now placed in an atmosphere of nitrogen, it continues to burn and forms a compound ‘Y’. Write a balanced chemical equation when ‘X’ is dissolved in water.
A. 2 Mg + O2→2MgO
B. 3 Mg + N2→Mg3N2
C. MgO + H2O→Mg(OH)2
D. Mg + H2O→Mg(OH)2
