a. What is the ratio of the mass of A to the mass of B in each sample?
b. How do these ratios compare?
c. What can you conclude about the samples?
d. Assume that the chemist was looking for a compound that is 66.67% A and 33.33% B. How could the chemist determine
successful in finding this compound?

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
