Consider a 100 kw fuel cell power plant that is fueled with natural gas that has a lower heating value of 48.3 mj/kg. based on the lower heating value of the fuel, the power plant has a heat rate of 7500 btu/kwhe. the fuel cell is a combined heat and power (chp) plant which produces 200,000 btu/h of heat energy at rated power. assume natural gas has a carbon content of 70% (wt). how much co2 is produced per mwhe if only the electrical power is used and the heat is discarded (kgco2/mwhe)?

If 34.2 grams of lithium react with excess water, how many liters of hydrogen gas can be produced at 299 kelvin and 1.21 atmospheres? 2 li (s) + 2 h2o (l) yields 2 lioh (aq) + h2 (g)
