Methane (also known as natural gas) is combusted with oxygen to produce heat according to the following reaction: CH4(g) + 2 O2(g) → CO2(g) + 2 H2O(g), AHrxn = -890.8 kJ How many moles of methane must be combusted to increase the temperature of 100.0 g of water from an initial temperature of 20.0 °C to a final temperature of 90.0 °C? The specific heat capacity of water is Cs = 4.184 J/g.°C. %3D
