Bio-gas digestion system
Methane Gas The combustion of methane is a very exothermic reaction (ΔH = -891 kJ/mol) Main component of "natural gas Can be found Underground Swamps and marshes Livestock (methanogenic bacteria)
Something we may not know Cow can produce a lot of gas per day
How to Simple equipment to recreate fart Create methane using daily food waste vegetables fruit
Lab Create a smaller scale system Measure how much gas produce per pound of food Using the result to calculate the energy the process can produce
Product Gas (methane) Fertilizer
Enthalpy of Combustion Calculations. Example Q. 4.6g of ethanol (C 2 H 5 OH) is burned. The energy released raised the temperature of 0.5kg of water by.

Bond Enthalpies Section 5.4. Introduction More Good Stuff For H 2 the thermochemical equation describing the bond enthalpy is: H 2(g) → 2H (g) ∆H θ =
Measuring and Expressing Heat Changes Enthalpy The heat content of a substance that has at given temperature and pressure Change in heat content.
Today, we will burn a gummy worm containing 2.1 g of sucrose (C 12 H 22 O 11 ). When one mole of sucrose burns in oxygen gas, it produces carbon dioxide.
