An expandable container of oxygen has a volume of 30.0mL at a pressure of 36.7psi. If the pressure of the oxygen is reduced to 2
ELEN [110]

Answer:44.04mL

Explanation:Parameters given

V1 = 30.0mL

P1 = 36.7psi

P2 = 25.0psi

V2 = ??

From Boyle's gas law, which states that "the pressure of a given mass of an ideal gas is inversely proportional to its volume at a constant temperature"

This means that,

the pressure of a gas tends to increase as the volume of the container decreases, and also the pressure of a gas tends to decrease as the volume of the container increases.

Mathematically, Boyle's can be represented as shown below

P= k/V

Where P = Pressure, V = Volume and k is constant

Therefore,

PV = k

P1V1 = P2V2 =PnVn

Using the formula

P1V1 = P2V2

V2 = P1V1/P2

V2 = (36.7psi × 30.0mL) / 25.0psi

V2 = 1101.0/25.0

V2 = 44.04mL

Which of the two types of synthetic polymer is more similar chemically to biopolymers? Explain.
loris [4]

Natural polymer is more similar chemically to biopolymers.

Polymers are large molecules or high-molecular weight compounds formed from small repeating units. These repeating units are called monomer. Polymers are synthesized naturally and artificially. The number of repeating units in a chain is called the degree of polymerization.

There are two types of polymers:

1. Natural Polymers

2. Synthetic Polymers

Biopolymers are natural polymers produced by the cells of living organisms. Biopolymers consist of monomeric units that are covalently bonded to form larger molecules.

Synthetic polymers are the human-made polymers sometimes referred as plastics. The two major types of synthetic polymers are addition polymers and condensation polymers.

What are biopolymers?

Biopolymers polymer materials that form in living organisms. There are three main biopolymers in living systems; polysaccharides, proteins and polynucleotides (nucleic acids). The structural unit of polysaccharides is monosaccharides (sugars). When two monosaccharides join together to form a glycosidic bond, it releases a water molecule. Therefore, polysaccharides are condensation polymers. Polysaccharides play structural and functional roles in organisms. Glycogen is a storage polysaccharide, whereas cellulose is a component in the cell walls of plant cells. Glucose is the monomer for both glycogen and cellulose polymers.

Hence, we have conclude Biopolymers  are natural polymers produced by the cells of living organisms. Biopolymers consist of monomeric units that are covalently bonded to form larger molecules.
