Seizure

In 2008, the artist Roger Hiorns filled an abandoned waterproofed building London with 75,000 liters of copper sulfate solution. The solution was left to crystallize for several weeks before the flat was drained, leaving crystal-covered walls, floors and ceilings. The work is titled Seizure.^[19]

So what's a hydrate?  watch this video.

For starters, print out this worksheet including the answer sheet--it should answer some of your questions about hydrates. You can try to answer the questions or just straight out copy.

For homework finish up Monday's lab on Percent Composition, as best you are able. SHOW YOUR WORK!!!

You will be asked for the "empirical formula." What is that? Watch this video.

The extra worksheet, "Determining the formula of a hydrate," given out in class, or here, should be of help.   READ it! and follow the steps.  Make a data table for each problem and show your work You will not get a perfect number from your class experiment--there was just too much error involved, mostly my fault for not preparing you well enough and not problem shooting ahead of time--BUT this worksheet will help you find the THEORETICAL FORMULA  for CuSO4 or MgSO4.[that is to say, how many H2Os are attached to each ionic compound unit]   Solve problems 1-4.  Make a data table for each problem and show your work.  Life has no answer book, so always show your work.  I will be collecting and correcting homework from now on, so be legible.

Bragging rights for doing this on your own.
