Nitrogen and Sulfur

Question 1

How are photochemical smog formed

Answer 1

Nitrogen Oxides reacts with unburnt hydrocarbon which forms PAN

Question 2

Equation of how catalytic converter reduces the amount of nitrogen oxides gases released into the atmosphere

Answer 2

2NO + 2CO —> 2CO2 + N2

Question 3

Reagent required to make NH3 (g) into NH4Cl (s)

Answer 3

Ca(OH)2

Question 4

equation of formation of acid rain

Answer 4

2NO(g) + O2(g) ⇌ 2NO2(g)

• Then NO2 reacts with rain and oxygen in the

4NO2(aq) + 2H2O(l) + O2(g) —> 4HNO3(aq)

Question 5

What does NO2 catalyse

Answer 5

Oxidation of SO2 to SO3

NO2(g) + SO2(g) —> SO3(g) + NO(g)
