1. Develop a reaction equation for the combustion of polyethylene, [CH2CH2]n, in 100.% theoretical air.
2. A simple alcohol can be obtained from a hydrocarbon by replacing one of the hydrogen atoms by a hydroxyl group (OH). Develop a reaction equation for the combustion of a generalized alcohol of this type, CnH2n+1(OH), in 100.% theoretical air and test it out with
a. Methyl alcohol (also known as methanol or wood alcohol), CH3(OH).
b. Ethyl alcohol (also known as ethanol or grain alcohol), C2H5(Oh).
c. Isopropyl alcohol, C3H7(OH).

Carbon dioxide is dissolved in blood to form a mixture of carbonic acid and bicarbonate. Neglecting free CO2 what fraction will be present as carbonic acid?
The volume of seawater on Earth is about 3.3 x 10^8 mi^3. Because it contains salts, mostly sodium chloride, its density is about 1.03 g/mL, a little higher than that of pure water. The concentration of sodium chloride is about 3.5% by mass.c
