c.

The pie chart shows different sources of emissions of sulfur dioxide.

A pie chart showing different sources of sulfur dioxide emissions. The sectors are: Electricity generation at 55%, Transport at 15%, Domestic heating at 6%, Agriculture at 5%, Other at 4%, and Industrial processes which has no percentage label.

Calculate the percentage emissions of sulfur dioxide from industrial processes. Percentage emissions from industrial processes = _____________ %

d.

What is the largest source of emissions of sulfur dioxide?

e.

A catalytic converter on a car removes nitrogen monoxide and carbon monoxide from exhaust gases. Nitrogen gas and carbon dioxide gas are made.

This is the balanced equation for the reaction that takes place: 2CO+2NO→N2+2CO22\text{CO} + 2\text{NO} \rightarrow \text{N}_2 + 2\text{CO}_22CO+2NO→N2​+2CO2​

On a car journey, 2.82.82.8 tonnes of nitrogen is made.

Calculate the mass of nitrogen monoxide removed from the exhaust gases.

Relative atomic mass (ArA_rAr​): N=14.0\text{N} = 14.0N=14.0, O=16.0\text{O} = 16.0O=16.0. Mass of nitrogen monoxide = _____________ tonnes
