Answer:
Explanation:
Hello!
In this case, considering the balanced chemical reaction:
Cl₂ + 2LiI ⇒ 2LiCl + I₂
We can see there is a 1:1 mole ratio between the produced iodine and the used chlorine, thus, we infer that the number of molecules of iodine given those of chlorine turn out:
Best regards!
The total pressure is the sum of all the partial pressures of the different components in the system. In this case, if the total pressure is 520 torr, and the partial pressure of nitrogen is 266 torr, and the only components are nitrogen and sulfur dioxide, this means that the rest of the pressure is all due to sulfur dioxide.
So the partial pressure of sulfur dioxide = 520 - 266 = 254 torr SO2.
The number that never changes is the atomic mass (atomic number on the periodic table)
Use the formula q=m×Cp×delta T
m=1.500 kg=1,500 g
Co=2.52 J/g·k
delta T=0.985k
q=(1,500g)(2.52 J/g·k)(0.985k)
=3,723.3 J=3.72
I JUST FINISHED THIS QUESTION AND IT SAID THAT THE ANSWER WAS -3.72 kJ SO PUT THAT DOWN AS YOUR ANSWER....I'm not sure why the answer is negative, but this is the most work I can show. If any one knows, why this answer is negative, please advise. Thank you. I hope that this helps :)
