The diagram shows the setup of an experiment. A few observations of the experiment are listed in the table below the diagram. 1 Color of Solution turned blue
2 Shiny hair like crystals deposited on the copper strip

Which of the following is the correct explanation for one of the given observations?

A) observation 1 is a result of silver ions moving into the solution.
B) observation 2 is a result of nitrate ions moving into the solution
C) observation 1 is a result of silver ions changing their oxidation state
D) observation 2 is a result of silver ions changing their oxidation state

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.
