How much heat is given off when 32g liquid methanol (ch3oh) at its freezing point changes to solid methanol? (methanol hf=3.16 kj/mol)

a)1.58 kj
b)3.16 kj
c)0.79 kj
d) 0.18 kj

The correct answer is option B.

Explanation:

Mass of methanol = 32 g

Molar mass of methanol = 32 g/mol

Moles of methanol =

Heat of fusion of methanol =

Amount energy released when 1 mol of methanol is freezes = 3.16 kJ

The correct answer is option B.

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
