1.

– a lot of energy is required. Since it provides 1% of drinking water but takes 12500 desalination plants
– expensive
– requires more land use

2.

Only water soluble vitamins are polar, because like dissolves like. Fat-soluble vitamins are non-polar therefore making them hydrophobic. A fat molecule has a hydrophilic head and hydrophobic tail. The fat-soluble vitamin will therefore choose the hydrophobic, non-polar tail to dissolve in.

3.

(a) reduce use of dryer. So the electricity consumption is reduced. Thus amount of Sox produced from power plant is reduced.
(b) less Nix produced by automobiles
(c) save electricity thus less Sox produced by power plants
(d) same as (c)
(e) less shipping, so less fuel consumption, and less Nix produced

4.

(a) coal-fired plants release SO2 -> sulphate particles that results in poor visibility. Sulphate particles reflect sunlight and results in low visibility.

(b) normal rain has a natural pH of 5-6. Thus 10 times more acidic than natural meant that pH will decrease by 1 unit. Thus resulting in an estimated pH of 4-5 at the park.
