The table below displays properties of three alternative fuels derived from agricultural and industrial waste:

Table 1: Properties of three waste-derived fuels

Property	Fuel P (Pyrolysis oil)	Fuel Q (Straw briquettes)	Fuel R (Bio-hydrogen)
Physical state at room temperature	Liquid	Solid	Gas
Primary transportation method	Tanker	Truck	Pipeline
Percentage by mass of sulfur in fuel (%)	0.12	0.35	0.00
Relative emission level of soot/particulates	Medium	High	Negligible

Using this information, answer the following questions:

Explain why Fuel Q (Straw briquettes) is typically transported by truck and cannot be distributed via a pipeline.

Equal masses of each fuel are burned under identical conditions. State which fuel produces the most sulfur dioxide and justify your choice using data from the table.

State one environmental problem caused by sulfur dioxide emissions.

Particulates (soot) are formed during incomplete combustion. Identify the reactant that must be in limited supply for incomplete combustion of these fuels to occur.
