Ii) prepare a stock solution of isopropanol 1) prepare 25.00 ml of solution which is 0.60 m in isopropanol (0.785 g/ml) and 1.00 m in hcl. add the reagents in the following order into the volumetric flask provided: about 10 ml of deionized water 2.0 m hcl (use a graduated cylinder--if the flask gets warm, cool it in running tap water, but be careful not to get tap water into the flask) isopropanol (use a 1 ml graduated pipet).

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.
