Quantitative Chemical Analysis 8
Consider a mixture of the two solids, BaCl2 2H2O (FM 244.26) and KCl (FM 74.551), in an unknown ratio. (The notation BaCl2  2H2O means that a crystal is formed with two water molecules for each BaCl2.) When the unknown is heated to 160C for 1 h, the water of crystallization is driven off: A sample

Urban Economics 8
Consider Snarlsville, a city that will vote on a proposed revenue-neutral con- gestion tax. Consider the following statement from the Chamber of Commerce: The tax will be bad for business, so we urge all business owners to vote NO. Suppose bad for business means sales revenue will decrease. a. The co
