Answer:

Pressure = 4.81atm

Explanation:

Pressure = ?

Temperature = 20°C = (20 + 273.15)K = 293.15K

Volume = 2.50L

R = 0.082J/mol.K

n = 0.5mol

From ideal gas equation,

PV = nRT

P = pressure of the ideal gas

V = volume the gas occupies

n = number of moles of the gas

R = ideal gas constant and may varies due to unit of pressure and volume

T = temperature of the ideal gas

PV = nRT

Solve for P,

P = nRT/ V

P = (0.5 * 0.082 * 293.15) / 2.50

P = 12.01915 / 2.50

P = 4.807atm

P = 4.81atm

The pressure of the ideal gas is 4.81atm

Describe how nucleic acid basis pair up
castortr0y [4]

The rules of base pairing (or nucleotide pairing) are: A with T: the purine adenine (A) always pairs with the pyrimidine thymine (T) C with G: the pyrimidine cytosine (C) always pairs with the purine guanine (G)

The nucleotides in a base pair are complementary which means their shape allows them to bond together with hydrogen bonds. The A-T pair forms two hydrogen bonds. The C-G pair forms three. The hydrogen bonding between complementary bases holds the two strands of DNA together.
