Which air is driest? Group of answer choices Air Temp 30F Dew-point 29F Air Temp 50F Dew-point 36F Air Temp 77F Dew-point 19F Air Temp 66F Dew-point 60F

C. Air Temp 77F Dew-point 19F

Explanation:

The further the separation between the temperature and the dew-point allows for a drier object.

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7
