It is the main component of acid rain. It is released into the air as a result of the burning of fossil fuels.
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).
Given :
Mass of granite , m = 20 g .
Change in temperature , 
.
Specific heat capacity of granite , 
.
To Find :
The heat absorbed by granite .
Solution :
We know , heat absorb is given by :
Therefore , heat absorb is 300.2 J .
Hence , this is the required solution .
Density is mass/ volume so 1300/743x10^3=.00174966
