When there is a decrease in the pressure or an increase in volume. As the container gets bigger, it will want to increase the pressure to get back to equilibrium. For that to happen, it will have to increase the number of gas moles, and since co2 is the only has in that equation, it will increase.
The only logical answer would be to D) draw a conclusion, given that an inference is another word for conclude. Helpful tip, if you are dealing with the scientific method just google the method and boom! there is your answer.
Hydrogen bonds.

Answer:- The right choice is A.
.
Solution:- Latent heat of fusion means the heat required to melt the solid at constant temperature means there is no change in temperature only the solid changes to liquid. So, it is a solid to liquid phase change.

where q is the heat required to convert solid to liquid, m is the mass and
is the latent heat of fusion.
From given info, 550 kJ that is 550000 J of heat is required to melt 14 kg of solid at 262K temperature. Let's rearrange the equation for latent heat of fusion and plug in the values in it.


= 
If we round this value to two sig figs and write in scientific notations then it becomes
.
So, the right choice is A.
