Nitrogen and Sulfur

Question 1

Nitrogen is a diatomic molecule

Explain it’s configuration

Answer 1

Nitrogen’s atoms need to gain three electrons to achieve the noble gas configuration of neon
It does this by forming a triple covalent bond 
The N(triple bond)N is nearly six times as strong as the N-N bond making it extremely hard to break and making N2 extreme unreactive

Question 2

Why does ammonia act as a base

Answer 2

Because Nitrogen has a lone pair of electrons and will accept protons

Question 3

Displacement of ammonia from its salts

Answer 3

Any ammonium salt+any base—>ammonia gas+salt+water

Question 4

Ammonia uses

Answer 4

Fertilisers
Production of nitric acid
Nylon
Explosives

Question 5

Sulfur dioxide

Answer 5

Main cause of acid rain
Oxides of nitrogen catalyse the oxidation of sulfur suicide to sulfur trioxide which then reacts with water to form sulfuric acid which is the main cause of acid rain

Question 6

Sulfur dioxide formation

Answer 6

When we burn fossil fuels that contain sulfur impurities

When the fossil fuels are burnt the sulfur impurities get oxidised
