mass of Cl₂ = 8.61 grams
Explanation:
We have 2.75 of chlorine (Cl₂) which is gas. If we assume that it is behaving like an ideal gas and we work under standard conditions, we can use the following equation.
number of moles = volume / 22.4 (L / mole)
number of moles of Cl₂ = 2.75 / 22.4 = 0.123 moles
number of moles = mass / molecular weight
mass = number of moles × molecular weight
mass of Cl₂ = 0.123 × 71 = 8.61 grams

<u>Answer:</u> The final temperature of the gas is -220.6°C
<u>Explanation:</u>
To calculate the final temperature of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
where,
are the initial pressure and temperature of the gas.
are the final pressure and temperature of the gas.
We are given:
![P_1=6atm\\T_1=-33^oC=[273-33]K=240K\\P_2=1.31atm\\T_2=?](https://tex.z-dn.net/?f=P_1%3D6atm%5C%5CT_1%3D-33%5EoC%3D%5B273-33%5DK%3D240K%5C%5CP_2%3D1.31atm%5C%5CT_2%3D%3F)
Putting values in above equation, we get:
Converting the temperature from kelvins to degree Celsius, by using the conversion factor:
Hence, the final temperature of the gas is -220.6°C
Answer:
Option D. 17.5
Explanation:
Equiibrium is: CO + 2H₂ ⇄ CH₃OH
1 mol of CO is in equibrium with 2 moles of hydrogen in order to make, methanol.
Initially we have 0.42 moles of CO and 0.42 moles of H₂
If 0.29 moles of CO remained, (0.42 - 0.29) = 0.13 moles have reacted.
So in the equilibrium we may have:
0.29 moles of CO, and (0.42 - 0.13 . 2) = 0.16 moles of H₂
Ratio is 1:2, if 0.13 moles of CO haved reacted, (0.13 . 2) moles have reacted of hydrogen
Finally 0.13 moles of methanol, are found after the equilibrium reach the end.
Let's make expression for KC: [Methanol] / [CO] . [Hydrogen]²
0.13 / (0.29 . 0.16²)
Kc = 17.5
Compound: a thing that is composed of two or more separate elements, basically it is a mixture
Mixture: a substance made by mixing other substances together
