A table tennis ball has a mass of 2.7 x 10-3 kg. How much energy would be produced if the mass of the table tennis ball were converted into energy? (The mass-energy equivalence equation and speed of light are given below.) E = mc2 c=3.0 108 m/s

Amixture of gaseous sulfur dioxide and oxygen are added to a reaction vessel and heated to 1000 k where they react to form so3(g). if the vessel contains 0.669 atm so2(g), 0.395 atm o2(g), and 0.0851 atm so3(g) after the system has reached equilibrium, what is the equilibrium constant kp for the reaction: 2 so2(g) o2(g) ⇌ 2 so3(g)
