Answer: the equilibrium will be displaced to the right leading an increase on the quantities of y(g) and z(s).
Justification:
According to the rules of equilibrium, based on Le Chatellier's priciple, any change in a system in equilibrium will be tried to be compensated to restablish the equilibrium
The higher the amount, and so the concentration, of X(g), the more will the forward reaction proceed leading to an increase on the concentration of the products y(g) and z (s). Look that that will also be accompanied by a decreasing on the pressure, since 2 molecules of the gas X(g) are converted into 1 molecule of the gas y(g).

Answer:</h2><h2>
The percentage of the family’s total annual electricity that is used to run the two air conditioners for the three summer months = 19.4 %</h2>
Explanation:
Average electricity consumed per month = 900 kWh
The family cools their house for three months during the summer with two window-unit air conditioners
The power consumed by one window-unit air conditioners = 350 kWh
The power consumed by two window-unit air conditioners = 350(2) = 700 kWh
Power consumed for two air conditioners for the three summer months = 700 (3) = 2100 kWh
Total power consumed for 1 year = 900 (12) = 10800kWh
The percentage of the family’s total annual electricity that is used to run the two air conditioners for the three summer months =
= 19.4 %
Answer:
20L
Explanation:
The following data were obtained from the question:
Initial volume (V1) = 10L
Initial Temperature (T1) = stp = 273K
Final temperature (T2) = 546K
Final volume (V2) =..?
The new volume of the gas can be obtained by using the Charles' law equation as shown below:
V1/T1 = V2/T2
10/273 = V2/546
Cross multiply to express in linear form
273 x V2 = 10 x 546
Divide both side by 273
V2 = (10 x 546) / 273
V2 = 20L
Therefore, the new volume of the gas is 20L.
The force on the wall is actually the pressure exerted by gas molecules
Higher the pressure more the force exerted on the walls of container
The pressure depends upon the number of molecules of a gas
In a mixture of gas the pressure depends upon the mole fraction of the gas
As given the mole fraction of He is more than that of H2 therefore He will exert more pressure on the wall
The ratio of impact will be
H2 / He = 2/3 / 1/3 = 2: 1
