What will happen to the pressure inside a closed container of gas if more gas is added to the container? a. the pressure will increase because the force of the collisions between the gas particles and the walls of the container will increase. b. the pressure will increase because the number of gas particles colliding with the walls of the container will increase. c. the pressure will decrease because the temperature inside the container will increase. d. the pressure will decrease because the volume of the container will increase.

i believe the answer is c. "baking" is the gerund, while "baking blueberry muffins" would be the gerund phrase. hope this ! : )

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
