Answer:
And what is your question
Explanation:
Answer:
T₂ = 221.8 K
Explanation:
Given data:
Initial temperature = 57.9°C ( 57.9+273 =330.9 k)
Initial volume = 75.8 mL
Final volume = 50.8 mL
Final temperature = ?
Solution:
According to Charles's law,
V₁ /T₁= V₂/T₂
T₂ = V₂T₁/V₁
T₂ = 50.8 mL ×330.9 k / 75.8 mL
T₂ = 16809.72 mL.K/ 75.8 mL
T₂ = 221.8 K

Answer:
The answer to your question is the letter d. -132.8 kJ
Explanation:
To solve this problem, just observe that the ΔH is originally equal to +66.4 kJ.
If we change the order of the reaction, ΔH changes its sign but the value is the same.
Finally, if we duplicate the number of moles, also the ΔH increases twice.
For this problem
ΔH = 2(-66.4 kJ)
ΔH = - 132.8 kJ
