11 Question (3 points) See page 247 Copper has been used for thousands of years, either as a pure metal or in alloys. It is frequently used today in the production of wires and cables. Copper can be obtained through smelting or recycling. Determine the energy associated with each of these processes in order to recycle 145 mol Cu The smelting of copper occurs by the balanced chemical equation: Cuo(4) + CO(g) – Cu(s) + CO,(g) where AH cuois -155...

General Chemistry II Part II. Fuel efficiency (6 pts) Fuel efficiency is the efficiency of the conversion of chemical energy contained in a fuel into work. Let's see which one of these fuels (hydrogen gas or liquid propane) will allow us to do more electrical work. Use the thermodynamic data provided to answer the following questions: 1. First determine the amount of heat released in direct combustion of (a) 1 mole of hydrogen gas; (b) 1 mole of liquid propane...
