My favorite thing is supreme. this is me

it was Penelope Paige when you plug in 9.8 to 11.8 inches for the size of the footprint you get the person is between 61 and 70 inches. if you convert the height of Penelope Paige (5'4") to inches its 64 inches which is between 61 and 70 inches she is the only one that fits the description of the footprints left at the crime scene.

Effects of Concentration on solubility Lab

1. Add 70 mL of distilled water to a clean 100 mL beaker

2. Switch on the Conductivity Probe to the 0-2000 us/cm range

3.Setup EasyData for Data Collection

4. Add 1 drop of salt solution to the distilled water. Continue this procedure adding 1 drop at a time until 8 drops have been added. Recording each time. do this for all 3 solutions.

5.Select Stop when you finish collecting data.

6. Analyze the relationship between conductivity and volume. y=mx+b

Determining The Ksp of Calcium Hydroxide Lab

1. Obtain and Wear goggles



2. Measure exactly 15 mL of the solution into a 50 mL beaker



3. Position the pH sensor in the Ca(OH)2 solution



4. Add the pH Sensor in the Ca(OH)2 solution. It should be above 7.

5. Check the initial volume of the buret. Slowly add the 0.05 M HCl until the pH reaches 7.
