Nucleic acids are hydrocarbons that also contain nitrogen, phosphorus and oxygen elements.
Hydrocarbons are long chains of carbon that have additional bonds exclusively with hydrogen atoms. They are hydrophobic, or not soluble in water. Nucleic acids are macromolecules that are made of units called nucleotides, they are mainly in two forms; the RNA and and the DNA. Both the RNA and DNA have a pentose sugar, a phosphate, and a nitrogen containing base.
Explanation:
According to the given data, the turnover number can be calculated as follows.
Turnover number = 
Therefore, moles of 
hydrolyzed is as follows.
Moles of hydrolyzed = 
= 
= 0.00682 moles
Now, moles of hydolyzed per second is calculated as follows.
Moles of hydolyzed per second = 
= 
And,
Moles of enzyme = 
= 
= 
moles
Therefore, the value of 
is as follows.
= 
per second
= 
per minute
= 
per minute
Thus, we can conclude that the turnover number () of carbonic anhydrase (in units of 
) is per minute.

Industry uses only about 18% while the others use around 70-90% of water.

What is vapor pressure in science definition?
- Vapour pressure is a measure of the tendency of a material to change into the gaseous or vapour state, and it increases with temperature.
- The temperature at which the vapour pressure at the surface of a liquid becomes equal to the pressure exerted by the surroundings is called the boiling point of the liquid.
We will use the Clausius-Clapeyron equation,
ln(P2/P1) = dHvap/R[1/T1-1/T2]
where,
P1 = unknown
P2 = 1 atm
T1 = 30 oC = 30 + 273 = 303 K
T2 = 78.3 oC = 78.3 + 273 = 351.3 K
dHvap = 39.3 kJ/mol = 39300 J/mol
R = 8.314 J/K.mol
Feed values,
ln(1/P1) = 39300/8.314[1/303 - 1/351.3]
P1 = 0.12 atm
thus, the vapor pressure at 30° C is 0.12 atm.
