Which answer best describes what is happening in the following reaction? 2c8h18 + 25o2 mc022-1.jpg 16co2 + 18h2o this is not a redox reaction. it is an example of combustion. this is a redox reaction in which octane (c8h18) is oxidized. this is a redox reaction in which carbon dioxide (co2) burns due to ignition. this is not a redox reaction, because a solution of carbon dioxide and water results.

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.
