15 in the chemical reaction where n2o4(g) is converted to 2no2(g), if 0.5 m n2o4 and 0.15 m no2 are present in the vessel, is the reaction at equilibrium? if not, which direction would the reaction proceed? (kc = 4.4 × 10-3) n2o4(g) 2no2(g) no, q = 9.0 × 10-2 so the reaction should proceed in the reverse direction. no, q = 0.18 so the reaction should proceed in the forward direction. no, q = 4.5 ×10-2 so the reaction should proceed in the reverse direction. yes, the reaction is at equilibrium.

It takes 945.kj/mol to break a nitrogen-nitrogen triple bond. calculate the maximum wavelength of light for which a nitrogen-nitrogen triple bond could be broken by absorbing a single photon.

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.

What will most likely happen in the absence of a cell membrane? a) photosynthesis will not take place. b) the cell will not store food, water, nutrients, and waste. c) energy will not be released during cellular respiration. d) substances will pass in and out of the cell in an uncontrolled manner.
