Methane and hydrogen sulfide gases react to form carbon disulfide and hydrogen gas(es). CH4(g) + 2 H2S(g) CS2(g) + 4 H2(g) At a certain temperature and pressure 28.7 L of CH4 reacts with 57.4 L of H2S. If all the CH4 and H2S are consumed, what volume of CS2 and H2 combined, at the same temperature and pressure, will be produced? a) 10.8 L of CS2 and H2 combined will be formed. b) 86.1 L of CS2 and H2 combined will be formed. c) 40.2 L of CS2 and H2 combined will be formed. d) 144 L of CS2 and H2 combined will be formed. e) 47.8 L of CS2 and H2 combined will be formed.
