1. Calcium: When calcium is burnt in air, it reacts with oxygen to form calcium oxide (CaO) and calcium nitride (Ca3N2). The calcium oxide produced is a white solid, while the calcium nitride is a yellowish-brown solid. The reaction is exothermic and produces a bright orange flame.
2. Sulphur: When sulphur is burnt in air, it reacts with oxygen to form sulphur dioxide (SO2). The sulphur dioxide produced is a colorless gas with a pungent odor. The reaction is exothermic and produces a blue flame.
3. Sodium: When sodium is burnt in air, it reacts with oxygen to form sodium oxide (Na2O) and sodium peroxide (Na2O2). The sodium oxide produced is a white solid, while the sodium peroxide is a yellowish solid. The reaction is exothermic and produces a bright yellow flame.
2. Sulphur: When sulphur is burnt in air, it reacts with oxygen to form sulphur dioxide (SO2). The sulphur dioxide produced is a colorless gas with a pungent odor. The reaction is exothermic and produces a blue flame.
3. Sodium: When sodium is burnt in air, it reacts with oxygen to form sodium oxide (Na2O) and sodium peroxide (Na2O2). The sodium oxide produced is a white solid, while the sodium peroxide is a yellowish solid. The reaction is exothermic and produces a bright yellow flame.
