Answer the following questions in a clear, concise manner and showing all appropriate work for answers using math (as if it was a test) 
 
 
1a. In the Observation of the Chemical Reaction lab, what is the chemical formula for Copper (II) chloride or you could have called it Copper (II) chloride dihydrate ________________________ , 
 
1b. What phase is it right before you add the Aluminum to it?_________________________

2. From your data table in Density of Water Lab, write down the volume (in ml ) of the water for the Beaker section (make sure you put it's unit after it)

3. In the Observation of a Chemical Reaction Lab, write down one of your observation (can't use see permanent color change) that there was a chemical reaction when Aluminum was added to the solution and explain why the observation occurred (use information you obtained in the post lab discussion). 
 
 
 
 
 
4. On the back of this page, copy down your work to determine the density of the water (in the Density of Water Lab) using the Graduated cylinder including the Percent error (which I told you in class needed to be to one decimal place in answer).

5. In space provided, write down your answer to Question 4 of the Observation of a Chemical Reaction (will provide it here:) 
(You formed a solid. From your observations and know of the lab, what is this solid? How do you know (use lab data/observation)).
