Question

6. Gas reaction stoichiometry - combining volumes What is the final volume if 20 L methane reacts completely with 20 L oxygen CH_(4)(g)+2O_(2)(g)arrow CO_(2)(g)+2H_(2)O(l) At 100^circ C and 2 atmospheres a) 15L b) 10L C 20L d) 30L

Answer 1

To solve this problem, we need to use the concept of combining volumes in gas reactions.Given information:- 20 L of methane (CH4) reacts completely with 20 L of oxygen (O2).- The balanced chemical equation is: CH4(g) + 2O2(g) → CO2(g) + 2H2O(l).- The temperature is 100°C and the pressure is 2 atmospheres.According to the balanced chemical equation, 1 volume of methane reacts with 2 volumes of oxygen to produce 1 volume of carbon dioxide.Since the volumes of methane and oxygen are both 20 L, the methane will be completely consumed, and the oxygen will be in excess.The final volume of the reaction mixture will be equal to the volume of the limiting reactant, which is the methane in this case.Therefore, the final volume is 20 L.The correct answer is:c) 20 L
