Most carboxylic acids dissolve in aqueous solutions of sodium bicarbonate (NaHCO3) because they are more polar after they react to form carboxylate salts. Write curved arrows showing the reaction between a generic carboxylic acid and sodium bicarbonate to form a carboxylate salt and H2CO3. (Note that H2CO3 is unstable and decomposes to carbon dioxide and water.

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.
