Answer:
0.28M
Explanation:
From the question given, we obtained the following information:
C1 = 1.1 M
V1 = 125mL
V2 = 500mL
C2 =?
Using the dilution formula C1V1 = C2V2, we can easily find the molarity of the diluted solution as follows:
C1V1 = C2V2
1.1 x 125 = C2 x 500
Divide both side by 500
C2 = (1.1 x 125)/500 =
C2 = 0.28M
Answer: it is part of newtons second law. so the object to your question would accelerate
Explanation: newtons second law
Answer:
b. In equilibrium with the liquid phase, the pressure exerted by a gas.
Explanation:
When a liquid is warmed up to a temperature , it starts vaporising . The liquid is turning into gas and gas is turning into liquid at different rates . Initially the rate of former is higher but gradually the difference of rate between them decreases to zero . At this point the rate of conversion of liquid into gas and rate of conversion of gas into liquid becomes equal . This is called dynamic equilibrium point .
If we change the temperature , the equilibrium gets disturbed .
At this point the pressure exerted by the gas is called the vapour pressure of the liquid .
So option b ) is correct .
