Answer: The final temperature when heat in the amount of 800 kJ is added to 10 moles of ethylene initially at is .
Explanation:
It is known that the heat capacity of ethylene is 2.145 J/g K. Hence, for 10 moles of ethylene its mass will be as follows.
No. of moles =
10 mol =
mass = 280.5 g
Now, we know that relation between heat energy, mass and specific heat is as follows.
q =
1329.63 = T - 473
T = 1802.63 K
or, =
=
Thus, we can conclude that the final temperature when heat in the amount of 800 kJ is added to 10 moles of ethylene initially at is .

Answer:
Explanation:
Proteins have two main secondary structures: alpha helices, which are spirals formed by hydrogen bonds between amino acids, and beta pleated sheets, [ which are formed by a bend in the amino acid with alternating hydrogen bonding between amino acids.
