Two equilibrium reactions of nitrogen with oxygen, with their corresponding equilibrium constants (kc) at a certain temperature, are given below. reaction (1): n2(g) + o2(g) equilibrium reaction arrow 2 no(g); kc = 2.15e-31 reaction (2): n2(g) + 1/2 o2(g) equilibrium reaction arrow n2o(g); kc = 2.98e-24 using this set of data, determine the equilibrium constant for the following reaction, at the same temperature.

Unpolarized light of intensity so passes through two sheets of polarizing material whose transmission axes make an angle of 60∘ with each other as shown in the figure. what is the intensity of the transmitted beam, st?

Which statement is true? a. kepler's laws apply only to the motion of earth. b. kepler's laws can be used to predict eclipses. c. kepler's laws are true for a central force that is directly proportional to distance. d. kepler's laws can be deduced from newton's laws of motion and gravity.

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !
