Question

The statements given below are incorrect. Write the correct statements :

Calcium burns in oxygen with a golden-yellow flame.

Answer 1

Corrected statement: Sodium burns in oxygen with a golden-yellow flame.

• The given reaction is:
• $\underset{\mathrm{Sodium}}{4\mathrm{Na}\left(\mathrm{s}\right)}+\underset{\mathrm{Oxygen}}{{\mathrm{O}}_2\left(\mathrm{g}\right)}\to \underset{\mathrm{Sodium}\mathrm{Oxide}}{2{\mathrm{Na}}_2\mathrm{O}\left(\mathrm{s}\right)}$
• Calcium is quite reluctant to start burning but then bursts dramatically into flame, burning with an intense white flame with a tinge of red at the end.
