Biochemistry is focused on four biological molecules: proteins, carbohydrates, nucleic acids, and lipids. which can function as polymers? a. all are polymers. b. carbohydrates and proteins c. nucleic acids d. proteins, carbohydrates, and nucleic acids

The answer to your question is: A. All are polymers

Explanation:

Proteins are polymers that give structure to the cell, also they are enzyme which work in cellular metabolism, etc. The unit of proteins are aminoacids.

Carbohydrates are polymers that are the primary source of energy of the cells, their unit is monosaccharides.

Nucleic acids are polymers located in the nucleus of the cell, they particiated in the inheritance of traits. Their unit are nucleotides.

Lipids are polymers that form the cell membrane and give protection to the cell. Their unit is fatty acids.

a. All are polymers.

b. carbohydrates and proteins

c. nucleic acids

d. proteins, carbohydrates, and nucleic acids

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
