3. Adam wishes to make a battery which can generate electrical energy from the following
reaction:
Fe$O, (aq) + Mg(s) - MgSO (aq) + Fe(s)
As well as access to all common laboratory
equipment, Adam also has the following
chemicals at his disposal:
an aqueous solution of Feso. (1 M)
an aqueous solution of MgSO, (1 M)
an aqueous solution of KNO,
strips of Mg metal and Fe metal
Draw a labelled diagram to show how Adam
could use the above materials to generate a
battery and measure its voltage. Identify the
laboratory equipment he will need.

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.
