A sheep follows the arrows in the image around clockwise to eat grass. After a full day of eating grass, the sheep is back where it started. Answer the questions below using the image and information given. 5 km 2 km 2 km 5 km What distance did the sheep travel? What is the displacement of the sheep?

the answer is c.the valence of the atoms combine .

the answer is c i took the test

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
