Clouds are colloids. what are the dispersed particles

Water droplets slowly forming until they reach a size that can no longer be suspended in the air.  

Explanation:

When air becomes saturated with whater, it can no longer maintain water as a gas.  Some water molecule come together and stay that way.  They, in turn, coallesce with other nearby particles.  This continues until the droplets are large enough that they begin to noticeably refract the sunlight, producting the visual effect we call clouds.  The droplets are suspended in air - an heterogenous suspension called a colloid.  At some point the colloid cloud begins to shed the larger water droplets, usually directly over my spot on the trail.

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
