The combustion of hydrogen-oxygen mixtures is used to produce very high temperatures (ca. 2500 °C) needed for certain types of welding operations. Consider the reaction to be H2(g) + ½O2(g) - H,O(g) AH° = -241.8 kJ/mol What is the quantity of heat evolved, in kilojoules, when a 180 g mixture containing equal parts of H2 and O, by mass is burned?
