The turbines in a hydroelectric plant are fed by water falling from a 40 m height. Assuming 90% efficiency for conversion of potential to electrical energy, and 6% loss of the resulting power in transmission, what is the mass flow rate of water (in kg/min) required to power a 150 W light bulb?

Acetylene gas, C2H21g2, is used in welding. What is the maximum amount of useful work that can be accomplished under standard conditions by this reaction?
Alkali metals are often used to remove traces of water from organic solvents, such as diethyl ether. Because the reaction (see below) releases heat, care must be taken to make sure that the solvent does not "boil over". 2 Na(s) + 2 H₂O(1) ➜ 2 NaOH(aq) + H₂(g) a) Determine the standard enthalpy change for this reaction. Comment on the relative strength of bonding and/or interactions in the products vs reactants, and briefly explain how you decided this. Substance Na(s) H₂O(1) NaOH(aq) H₂(g) AHºf (kJ/mol) 0 -285.83 -469.15 0 b) How much heat (in kJ) is released via the reaction of 1.00 g of sodium metal with water? If this much heat is released into 275 g of diethyl ether initially at 25°C, will the solvent reach its boiling point? If so, how many grams of the ether will evaporate? Show calculations to support your answer. For diethyl ether: Cs = 2.51 J/g⋅K, b.p. = 35°C, heat of vaporization = 377 J/g.

2. The predominant forms of heavy metals (Zn, Pb, Fe, Cu, Ni, etc.) in aerobic sediments are the carbonates and the oxide or hydroxide forms. An important consideration in modeling the sediment is the stable chemical form of the metal in question. Consider the reaction: AG = 25 kJ/mol Pb(OH)₂ (s) + CO₂(aq) → PbCO₂ (s) + H₂O a. At what partial pressure of CO₂(g) will Pb(OH)2(s) and PbCO3(s) be at equilibrium? b. If the system is at equilibrium with the atmosphere, Pc02-10-3.38 atm, calculate 4G for the reaction.
