If you want to determine the actual salicylate concentration for a sample that gives a greater absorption than the highest concentration standard (as described in Question (3)), you need to dilute the sample. If you dilute it by mixing 0.25 mL of sample with 0.75 mL of water and then find that this mixture has a salicylate concentration of 0.45 mg/mL, what is the concentration of the unknown sample

Identify and describe the three ways that mutations affect organisms.

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.
