These techniques are expensive as they require the use of energy to remove salts from seawater/brackish water. Hence, incurring a higher cost. Mainly countries with strong economy are able to afford. If a cheaper option such as hauling fresh water from a distance is available, the more feasible option will be used.

We would expect the water-soluble vitamins to be polar and the fat-soluble vitamins to be non-polar. This is due the ‘like dissolve like’ property where water is polar and hence the water-soluble vitamins are soluble in water would be polar . If the fat-soluble vitamins dissolves in fats which is non-polar, the fat-soluble vitamins would be non-polar too.

a) Hanging the laundry to dry requires no electrical energy as it requires energy from the sun to dry. However if a electric dryer was use, it will require electricity and the power plant will need to burn more coal to produce electricity.

b) all the options are better as compared to driving. It is because the carbon emission for burning gasoline will be much higher than the options above.

c) By running these appliances in full loads will be better as it require less energy.

d) Adding additional insulation on hot water heaters and pipe would keep the water warm longer and the heater will not need to use much energy to reheat the water in the tank.

e) buying anything locally will be better as long distance transport contributes to more carbon emission into the atmosphere.

a) If there is a connection, it is because coal plants release huge amounts of water vapor along with the combustion process. The hydrogen and carbon in the coal make at least twice the amount of water vapor and small amounts of SO3 droplets as the coal burnt: CH4 + O2 —> CO2 + 2H2O.
Water vapor when cooled in the hilly forest area of this national park becomes visible as a fog. This happens in the Great Smoky Mountain Park area also, but is more because of all the lakes emitting vapor which cools at night and makes them look “smoky”.
So the connection is probably higher for coal plants in certain areas that have cooler night time temperatures that lead to high fog formation and cooler day temperatures that make the fog last longer

b) The average pH of rain should be neutral which is pH = 7. The pH scale is a log scale , so if the acid level is 10 times stronger that is equal to 1 pH. So in this case the pH would be pH 6.
