A sample of gas occupies a volume of 73.7 mL. As it expands, it does 133.7 J of work on its surroundings at a constant pressure

of 783 torr. What is the final volume of the gas?
A(S) + B(S) = C(g)
A(g)+B(g) = 3C(g)
A(g) + B(g) = C(g)
A(s) + 2B(g) = C(g)

In thermodynamics<span>, </span>work<span> performed by a system is the energy transferred by the system to its surroundings. It can be calculated by the expression:
</span>
W = PdV

Integrating,

We will have,

W = P(V2 - V1)
133.7 (1 litre-atm / 101.325 Joule) ( <span>760 Torr / atm ) </span>= 783 (V2 - .0737 )
V2 = 1.35 L

Hope this answers the question.  Have a nice day.

If, in a peptide chain, there were 85 amino acids each joined by peptide bonds, how many n-terminus groups would be present?
Crank
If, in a peptide chain, there were 85 amino acids each joined by peptide bonds, there would only be 1 N-terminus group that would be present. The N-terminus group is always the start of the chain of a amino acid chain or a protein or a polypeptide. It refers to the free amine group present that is located at the end part of the chain. So, that no matter how many amino acids in a chain there would always be only one N-terminus group.
