1.

1) Expensive, high cost
2) Not an efficient process, low output yield
3) Desalination has saline, brine by-products which must be disposed off properly

2.

Fat-soluble vitamins would be hydrophobic, and unable to dissolve in water, hence it is non-polar. Anything that is of non-polar nature will be dissolved by non-polar solvents.

Water-soluble vitamins dissolves in water, and would be polar since “like dissolves like”.

3.

a) Less electricity and power consumed, so less SO2 produced, causing less acid rain.
b) Less NO2 omission from vehicles, thus less acid rain.
c) Avoiding small loads is a more efficient use of electricity, less SO2 produced as compared to multiple loads.
d) Reduction of energy wastage for example, in heat escaping.
e) Minimal energy used to obtain same item, as compared to the transportation, packing etc. from distant countries

4.

a) Sulfate particles produced from coal-fired electric utility plants, when in humid environments, are effective in scattering light. Thus, reducing visibility.

b) Estimated pH value of 4-5.
