Book Free DemoA 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.
i. Write the chemical formulae of X and Y.
ii. Write a balanced chemical equation, when X is dissolved in water.
i. Write the chemical formulae of X and Y.
ii. Write a balanced chemical equation, when X is dissolved in water.
Magnesium ribbon burns in oxygen to form .
\(2Mg\) + \(O_2\) → \(2MgO\)
Burning magnesium ribbon reacts with nitrogen to form .
\(3Mg\) + \(N_2\) → \(Mg_3N_2\)
Therefore, the formula of \(X\) is \(MgO\) and \(Y\) is \(Mg_3N_2\).
We already know \(X\) is \(MgO\). It dissolved in water to form magnesium hydroxide.The balanced chemical equation for this reaction is .
