Two gas jars are connected to each other, but they are separated by a closed valve. One gas jar contains oxygen, and the other is empty. What will happen when the valve is opened? (3 points) a
Oxygen molecules will remain in their original jar because of the very high density of the oxygen molecules.

b
Oxygen molecules will remain in their original jar because there is enough space in the original jar.

c
Oxygen molecules will spread evenly throughout both jars because of weak intermolecular forces.

d
Oxygen molecules will spread through both jars because of the high molecular weight of oxygen.

Alice did an experiment to find the relationship between the angle at which a ray of light strikes a mirror and the angle at which the mirror reflects the light. she placed a ray box in front of a mirror. she changed the angle at which the light from the ray box struck the mirror and noted the corresponding angle at which the mirror reflected the light. which of the following is the dependent variable in this experiment? the mirror used to reflect the light the ray box used as the source of light angle at which the light from the ray box strikes the mirror angle at which the mirror reflects the light from the ray box
