Smoke screen is a mass of dense artificial smoke used to conceal military areas or operations from an enemy.It is produced by calcium phosphide. C a 3 P 2 + 6 H 2 O → 3 C a (O H) 2 + 2 P H 3. Phosphene (P H 3) so formed spontaneously catches fire to give P 2 O 5. 2 P H 3 + 4 O 2 → P 2 O 5 + 3 H 2 O. P 2 O 5 forms a white dense smoke screen ...
