The calorimeter pictured below shows the final temperature after calcium chloride was added to water. (The initial temperature was 25 °C.) Which of the following best describes what occurred within the calorimeter? A. Only bond forming occurred.
B. The bonds that formed were for the most part stronger than the bonds that were
broken.
C. More energy was absorbed in breaking bonds than was released when new
bonds form.
D. As the powder dissolved, the breaking of bonds released energy.

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.
