Questions:- (1)A farmer with 50 pigs proposed to use biogas generated from their wastes to power his motor car that uses 4 litres of petrol per day. (a) Discuss the feasibility of doing this. You should calculate both the energy content of gas and the energy used in compressing the gas to a usable volume, and compare these with the energy required to run the car. (b) Briefly comment on what other benefits (if any) he might gain by installing a digester. You may assume that a 100 kg pig excretes about 0.5kg of volatile solids (VS) per day (plus 6 kg water), and that 1 kg of VS yields 0.4m3 of biogas at STP.

Using Hess's Law to calculate net reaction enthalpy Dwayne The lead-acid storage battery is the oldest rechargeable battery in existence. It was invented in 1859 by French physician Gaston Plante and still retains application today, more than 150 years later. There are two reactions that take place during discharge of the lead-acid storage battery. In one step, sulfuric acid decomposes to form sulfur trioxide and water: H, SO (1) SO,(g) + II,0(1) AH= +113. kJ 圖 In another step, lead, lead(IV) oxide, and sulfur trioxide react to form lead(II) sulfate: alo Pb(1+ PbO,(s) + 2 SO,(g) 2 PbSO (s) AH = -775. kJ Calculate the net change in enthalpy for the formation of one mole of lead(II) sulfate from lead, lead(IV) oxide, and sulfuric acid from these reactions.
