You are in chemistry class and are looking at two samples of carbon and sodium on the lab table. A teacher asks which sample would weigh more and the class
can't decide. Below are 3 student opinions, which student is correct and why?
• Student #1: A mole of Carbon (C) would weigh more than a mole of Sodium
(Na)
• Student #2: A mole of Sodium (Na) would weigh more than a mole of Carbon
(C)
• Student #3: Each sample would have the same weight on the scale because
they're both a mole.

Which explanation is true about what happens to a ray of light when it strikes a mirror? a. a light ray is transmitted toward a mirror at a certain angle. the light ray is then reflected by the mirror at an equal angle but in the opposite direction of the transmitted ray. b. an incident ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then reflected at an angle equal to the angle of incidence but on the opposite side of the perpendicular line. c. a reflecting ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then refracted at an angle equal to the angle of the reflecting ray and on the same side of the perpendicular line. d. an incident ray strikes a mirror at an angle with a line parallel to the mirror. the light ray is then transmitted at an angle equal to the angle of incidence but on the opposite side of the parallel line. you so much! : -d take the time to try and answer correctly.
