In Part C of the experiment, you will need to prepare 60. mL of a solution that is 0.10 M in sodium hydrogen phosphate heptahydrate (Na2HPO4 · 7 H2O, MW = 268.1 g/mol) and 0.10 M in ascorbic acid (C6H8O6, MW = 176.1 g/mol). (a) How many grams of sodium hydrogen phosphate heptahydrate will you need? Report your answer to three significant figures. WebAssign will check your answer for the correct number of significant figures. g Na2HPO4 · 7 H2O

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.
