Answer:
<u>Part -A</u>
The change in the entropy from largest to smallest is 3>2=4 >1 >5>6.
<u>Part-B</u>
Change in entropy over a complete cycle is 1 =2 = 3= 4 = 5 = 6
Explanation:
<u>Part -A</u>
The change in entropy for the reversible process that transfers the heat energy 'Q' at temperature 'T' is
1)
2)
3)
4)
5)
6)
Therefore, The change in the entropy from largest to smallest is 3>2=4 >1 >5>6.
<u>Part-B</u>
Initial and final states of complete cycle are equal. after complete the one cycle the system returns to the original state. So, the change in the entropy will be the zero
Therefore, Change in the overall cycle is 1 =2 = 3= 4 =5=6
Answer:
The correct answer is -2952 KJ/mol
Explanation:
Attached is the diagram for Born- Haber cycle. According to the cycle:
ΔHf= ΔH1 + ΔH2 + ΔH3 + ΔH4 + ΔH5 + LE
In order to calculate the lattice energy (LE):
LE= ΔHf - ΔH1 - ΔH2 - ΔH3 - ΔH4 - ΔH5
LE= -1123 KJ/mol - 148 KJ/mol - 159 KJ/mol - 728 KJ/mol - 1450 KJ/mol - (2 x (-328 KJ/mol)
LE= -2952 KJ/mol
Answer:
b i think im not fully sure
Explanation:
Answer:
1 chlorine and 2 hydrogen
Explanation:
because in the picture you already have a hint wichbis chlorine so that eliminiates C and D
and its 2 hydrogens because if it were 1 then there wouldn't be anything adding in the chemical equation
