Leeward, because adiabatic heating is faster on the leeward side than the windward side due to its non-saturated air descent.
B I think but not 100% sure
Answers are:
1) shift to fossil fuels or coals with lower amount of sulfur.
2) removal (s<span>pray dry system</span>) of the sulfur oxide after combustion, removal sulfur during combustion (fluidised bed combustion) or reducing the sulpfur before combustion (washing the coal)<span>.
3) </span><span>improve efficiency of conversion of fuel and coal to electric power.

Answer:
0.0697 moles
Explanation:
We are being asked 4.2 x 10^22 atoms of aluminium to moles the following should be used for conversion.
Fraction of 1 mole Al over six point zero two two times ten to twenty third power atom Al.
that is 1 mole = 6.022 x10^23 atom
? = 4.2 x 10^22 atom
by cross multiplication
(1 mole x 4.2 x 10^22)/ 6.022 x 10^23 = 0.0697 moles
