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
Thermochemical Practice Problems
BIOGAS By Jenni, Tinh, Ly and Chau. Introduction To Biofuel Biofuels are fuels that have been developed from other materials such as plant matter and.
Page 34 In a chemical reaction, bonds in the reactants are broken and the atoms rearrange to form new bonds in the products. Flames or heat associated.
Thermochemistry Exothermic reactions release heat to the surroundings. Fe 2 O Al 2 Fe + Al 2 O kJ Potassium Permanganate Reaction Demo.
Entry Task: May 22nd 23rd Block 1
Q6 1. Bond Energy is the average energy required to break 1 mole of a covalent bond in the gaseous state. 2.
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 =
But more importantly is something called free energy G = H - TS want G to be negative, so that the free energy of the universe decreases, this is a spontaneous.
Enthalpy EQ: How do you predict the sign of delta H?
Higher Chemistry Unit 1(b) Enthalpy of combustion.
Calorimetry & Enthalpy Changes
What is biogas? A mixture of methane and carbon dioxide CH 4 CO 2 Methane or ‘swamp gas’, produced naturally in swampy ponds Methane or ‘swamp gas’, produced.
Enthalpy of Combustion
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.
OTHER IMPORTANT COMPONENTS OF DIET. RECAP: NUTRIENTS WE’VE COVERED SO FAR.. Macronutrients -carbohydrates -fats -proteins Micronutrients -minerals -vitamins.
How would you sort these?
Stoichiometry II. Solve stoichiometric problems involving moles, mass, and volume, given a balanced chemical reaction. Include: heat of reaction Additional.
