Water interacts with polar substances like –oh groups but not with non-polar substances like methyl (-ch3) or ethyl groups (-ch2). using this information, select the molecules that will easily dissolve in water based on polarity not on size. check all that apply.

b.) ch3oh
c.) ch3 ch3
d.) ch3 ch2 ch2 oh
e.) ch3 ch2 ch2 ch2 ch2 ch3

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.

When electrolyzing copper (ll) chloride, what reaction takes place at the anode? what reaction takes place at the cathode?

If anyone would be able to me out with these three questions it would be these are from the chem 2202 course.
