Answer: A 59.5 degree celcius
The equation that we will use to solve this problem is :
PV = nRT where:
P is the pressure of gas = 1.8 atm
V is the volume of gas = 18.2 liters
n is the number of moles of gas = 1.2 moles
R is the gas constant = 0.0821
T is the temperature required (calculated in kelvin)
Using these values to substitute in the equation, we find that:
(1.8)(18.2) = (1.2)(0.0821)(T)
T = 332.5 degree kelvin
The last step is to convert the degree kelvin into degree celcius:
T = 332.5 - 273 = 59.5 degree celcius
The water vapor will begin to contract. The particles will begin to bond with each other to seek heat so they're contracting.
Answer: Option (C) is the correct answer.
Explanation:
As the given reaction is as follows.
According to Le Chatelier's principle, any disturbance caused in an equilibrium reaction will shift the equilibrium in a direction that will oppose the change.
Hence, in order to favor the formation of products when we remove 
then there will occur decrease in it's concentration.
As is forming on the product side and equilibrium will shift in the direction where there is less stress.
Hence, then equilibrium will shift in the forward direction, that is, on the products side.
Thus, we can conclude that removing as it is formed would force the reaction to favor the products.
Answer: A
Explanation: Because a gas can turn into a liquid
