Suppose an iceberg with a mass of 1.00*10^13 kg is at a uniform temperature of 0.00C. The surrounding ocean has a temperature of 10.0C. A carnot heat engine used ocean water as a heat source and the iceburg as a heat sink. Assuming the waste heat of the engine provides all the heat necessary to melt the iceberg, how much work can this do?
A typical coal burning power plant produces 2000 MW of power. If the carnot engine in this problem was used to generate electricity, how long can the carnot replace a coal burning power plant before the iceberg melts?
How to calculate the volume of 1.5M aqueous pottasium hydroxide require to react completly with 2g of benzoic acid and extract the solution twice using the volume calculated?

If iron is oxidized to Fe2+ by a copper(II) sulfate solution, and 0.538 grams of iron and 13.0 mL of 0.40M copper(II) sulfate react to form as much product as possible.
An existing power plant has been found to produce SO2 concentration of 20?g/m3 at a distance of 800m directly downwind from the stack when the wind is 4m/s from the north during a class C stability situation.
