A magnesium ribbon is burnt in oxygen to...

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.
(a) Write the chemical formulae of X and Y.
(b) Write a balanced chemical equation, when X is dissolved in water.

Text Solution

Verified by Experts

`2Mg+O_(2)rarr2MgO+"Light"`
`3Mg+N_(2)rarrMg_(3)N_(2)`
(i) `X" is "MgO,Y" is "Mg_(3)N_(2)`
(ii) `MgO+H_(2)OrarrMg(OH)_(2)`
