Answer:
The new volume of the gas remains the same. That is new volume of gas is 1.33 litres
Explanation:
This is because gases do not have a definite shape. They therefore take the shape of their containing vessels and hence their volumes are determined by the volume of the container.
For the question above even if some of the gas escapes, as long as there is gas present in the container, its volume remains the same, that is occupies the same space in the container
Answer:
a) the system is closed
b) the system is open
Explanation:
a) the system can be characterised as closed system. If we define the boundaries of this system as an envelope that contains the bathtub, then there will not be any mass transfer to the environment through the boundary → then the system is closed ( the mass of the system remains constant)
b) on the other hand , taking the same system as in the first case, if the hot water is continually added to the tub , then there is water flow through the boundary (from the environment to the system) → then the system is open ( the mass of the system can be altered)
Answer:
1.4 * 10^-3
Explanation:
The equilibrium expression can be written as follows:
Keq = P [HD]^2/[ P[H2] * P[D2]]
Where P is pressure
1.80= (2.7 * 10^-3)^2 / ( 1.1 * 10^-3 * P[H2])
P[H2] = [2.7 * 10^-3]^2 / [1.8 * 1.1 * 10^-3]
P[H2] = 1.4 * 10^-3 atm
