1) An astronaut travels from Earth to Mars, where the gravitational field strength near the surface is 2 N/kg. The mass of the astronaut has a mass of 80 kg. take g on Earth= 10 N/kg. now the question: When the astronaut is near the surface on mars, what is his acceleration?

Chlorine and water react to form hydrogen chloride and oxygen, like this: 2cl2 (g) + 2h2o (g) → 4hcl (g) + o2 (g) also, a chemist finds that at a certain temperature the equilibrium mixture of chlorine, water, hydrogen chloride, and oxygen has the following composition: compound concentration at equilibrium cl2 0.55m h2o 0.57m hcl 0.53m o2 0.34m calculate the value of the equilibrium constant kc for this reaction. round your answer to 2 significant digits.
