Answer:
∆t(f) = 49.755C
Explanation:
Freezing point is defined as the point in which a liquid changes from liquid to solid state. Therefore, to calculate the freezing point of aqueous solution of propanol
∆t = k × I × m
Where k is cryscopic constant =
I = vant Hoff factor = 2
M = molar concentration = 12.25m
∆t (f) = 1.9 × 12.25 × 2 = 49.755C
Answer:
The process of breaking down stones or rocks into small pieces is called weathering.
Explanation:
Answer:
The correct answer:
8)- e)2, 2 dymetilpropane
9)- b) 2-chloropropane
10)- b) hydroxyl
See the explanation below, please.
Explanation:
In the cases of exercises 8 and 9:
Correspond to alkanes, having 3 carbons are named with the prefix prop and suffix anus. In 8 it has 2, 2 methyl groups in carbon and 9 in a 2-carbon chlorine group.
In the case of 10, it corresponds to a 3-carbon alcohol: suffix prop, and prefix ol: 2- propanol; in group 2 it has an OH group corresponding to alcohol (hydroxyl).
Covalent bonds is when polarity is formed
