Developing the Perfect Fertilizer

Purpose: To develop a new line of custom concentrations of liquid potassium nitrate fertilizer to organic farmers by finding the temperature that the maximum concentration of KNO3 that can be dissolved. Best fit line: y= .1825x+39

Conclusion: The line of best fit determines what temperature the solution needs to be at for the concentration. In 110g of KNO3 in 100g of water it will take 59.08 degrees Celsius. In 60g of KNO3 in 100g of water it will take 49.95 degrees Celsius. In 140g of KNO3 in 200g of water it will take 64.55 degrees Celsius. It is possible to make the orders because the solution dissolves at 39 degrees Celsius. Because the solution dissolves at 39 degrees Celsius it will easily dissolve at the higher temperatures therefore all of the farmers orders will be possible.

Drinking Water Contamination Kit Lab The solutions used in the experiment First FeCl2 solution was added across the first row Pb(NO3)2 was added across the second row AgNO3 was added across the third row Aluminum was added to the first row, copper added to the second row, iron was added to the third row, zinc was added to the fourth row This picture also shows the reactions CuSO4 solution is the first row and HCl is the solution of the second row Aluminum, copper, iron, and zinc were added in the same order. This picture shows the reactions

Determining of a Hydrate Procedure.... 1. Measure and record the mass of a clean, dry crucible 3. Measure & record the mass of the crucible and compound. 4. Gently heat the crucible for about ten minutes d 5. Turn off burner. Allow sample to gently cool for about ten minutes 6. When the crucible is cool enough to handle safely, record the mass of the crucible and its contents. 7.Repeat heating the crucible for five more minutes, allow it to cool, then re-measure its mass. 8. Repeat until there are two mass measurements that are within about 0.050 g of each other.

 The murderer could only possibly be Penelope Paige out of the three suspects because she fits the best. When her height was put into the equation the possible shoe size fit with her. It would have to be someone her size because you can wear bigger shoes but you cant wear smaller shoes. The other two suspects couldn't have worn the shoes. Her height correlated to the shoe size. the best. Therefore she is the best suspect to bring in out of the three. By putting the smaller shoe size number into the equation as 'y' and then solving for 'x' I got the number 54.1 in. for height. This matched the height of Penelope the best who is 54 inches.  I like strawberries and chicken. Not together though.
