Three bulbs are connected by tubing, and the tubing is evacuated. the volume of the tubing is 47.0 ml. the first bulb has a volume of 30.0 ml and contains 4.49 atm of argon, the second bulb has a volume of 250 ml and contains 2.64 atm of neon, and the third bulb has a volume of 21.0 ml and contains 9.36 atm of hydrogen. if the stopcocks (valves) that isolate all three bulbs are opened, what is the final pressure of the whole system in atm?

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.
