Im bored tell me you life story:

Everyday I sleep at either 7 am or 6 am and then my mother wakes me up at 8 am to do homework that is dumb and I'm just really tired. If she wants me to do my stuff don't wale me up an hour before I just go to sleep. This is so upsetting and she makes coffee but that does not help so now I just sit at the computer with them near me pretending to do my work and finish at a reasonable time.

Explanation:

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
