As temperature increases, the average kinetic energy of a sample of gas molecules decreases.
Answer:
The value of the equilibrium constant (K) remains the same.
Explanation:
A state of dynamic equilibrium is said to have been achieved in a reaction system when the rate of forward reaction equals the rate of reverse reaction.
At equilibrium, doubling the initial concentration of reactants have no effect on the equilibrium constant K. The equilibrium will rather shift to the left or right as required in order to annul the constraint.
Explanation:
When iodine heptafluoride reacts rapidly with water to give a mixture of periodic acid and hydrofluoric acid. Reaction equation for the same is as follows.
As it is given that there are 
moles of iodine heptafluoride are present. Molar mass of 
is 259.9 g/mol. Molar mass of 
is 227.94 g/mol and molar mass of HF is 20.01 g/mol.
Now, according to the reaction equation M gives M 
.
Also, the volume is given as 795 ml or 0.795 L (as 1 mL = 0.001 L).
Hence, calculate the concentration of into the solution as follows.
Concentration = 
= 
= 
mol/L
or, = 0.047 M
Now, as 1 mol of produces 7 mol HF. So, 
M HF.
Therefore, concentration of HF will be calculated as follows.
Concentration of HF = 
= 0.33 M
Thus, we can conclude that concentration of periodic acid is 0.047 M and concentration of hydrofluoric acid is 0.33 M.
I think the correct answer from the choices listed above is option C. Lotions applied during winter season moisturize the skin very quickly. This is because the oils in the lotion enter the skin cells by means of facilitated diffusion. Hope this answers the question.
