Explanation:
It'd be better to use cyclohexane. The possible explanation is that the freezing temperature will change by 20.1 degrees for each mole of substance added to 1 kg of cyclohexane, although the same amount added to naphthalene will change its freezing point just by 6.94 degrees.
It is so much easier to identify a larger change more adequately than a smaller one. You would actually not have a 1 molal solution in operation, so the variations in freezing points would be even smaller than the ones already described.
Answer:
13. D Hypothesis 14. A Analyze Matter, Solve Problems
Explanation:
I believe it’s D
There is good and bad bacteria that can be both harmful and good for humans
The correct answer is D
a polymer is a substance made up of large molecules with repeating sub units called monomers.
A is incorrect because its a ring structure which means it cannot form the long chain that is exhibited by polymers.
B is incorrect because the double bonds will cause saturation, hence no monomer can bond to another monomer to form the large molecule.
C is incorrect because the large molecule has repeating sub-units hence only specific types of molecules can be present, and it is usually carbon and hydrogen.
