Limestone rock is primarily calcium carbonate. This rock is particularly vulnerable to acid attack, reacting with hydrochloric acid to form calcium chloride, carbon dioxide gas, and water. For this reason, some fracking operations use a mixture of acids to open up the pores in limestone bedrock to improve natural gas extraction. If a 25.0g sample of limestone reacts with excess HCl, what volume (L) of carbon dioxide gas is formed at 752 mm Hg and 24LaTeX: ^\circ∘C.

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.
