What change would not result in a shift of the equilibrium position to the left? 2 a (g) + b (s) two arrows stacked on top of each other. the top arrow points to the right. the bottom arrow points to the left. 3 c (g) + energy increasing the pressure adding more of gas c to the system removing some of a from the system cooling the system

answer seismograph;

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
