10:40 5GE File Details CHEM&121 18612 - $22 - Introduction to Ch..... 1. The combustion of methane, CH4, releases 890,4 kl/mol. That is, when one mole of methane is burned, 890.4 kJ are given off to the surroundings. This means that the products have 890.4 kJ less than the reactants. Thus, DH for the reaction - 890,4 kJ. A negative symbol for DH indicates an exothermic reaction CH4 (g) +2 02 (g) C02 (g) + 2 H20 (1) DH=-890.4 kJ a) Draw an energy diagram (profile) for the above equation, label all parts b) How much energy is given off when 2.00 mol of CH4 are burned? c) How much energy is released when 22.4g of CH4 are burned? ◄ Previous Next 888 Dashboard Calendar To Do Notifications Inbox
