         The water stream bent toured the balloon but the balloon did not affect the vegetable oil.

        

   

Conclusion

          The reason that the water was attracted to the balloon and the vegetable oil was not. The balloon was eclectically charged and since water is a polar covalent compound the balloon and the water was eclectically attracted. The oil on the other hand was not attracted because of a lack of any electrical charge.

vinegar and baking soda

Results         

         The experiment had three different parts. Each step I used the same amount of vinegar 250mL. The baking soda was the thing that changed. The first step I used 10g the second was 30g and the third was 50g. The 10g made the least amount of gas only making the balloon have a 20-inch circumference. The 30g balloon had a 25-inch circumference. The 50g balloon had a 26-inch     circumference. The reason that the 50g balloon had almost the same amount of gas as the 30g balloon was that the vinegar is a limiting reaction. A limiting reaction is where there are two or more compounds in a reaction and one of the compounds runs out leaving excess of the other compound.

   

Conclusion

         When the HC₂H₃O₂ (l) and the NaHCO₃ (g) reaction happened it made H₂O (l), CO₂ (g) and NaC₂H₃O₂ (aq). this experiment would  have ben better if the balloon was larger because the ten grams of baking soda already had the balloon fully stretched. so when I used 30 grams of baking soda the ballon filled to its max and then just compressed the gas. 

   

                                                                          

  

                          
                                                                                                                                                                                                                                  

Results         

         In part A of the experiment when the Pb(NO₃)₂  was mixed with KI the solution turned a bright yellow. After ten minutes the reactions had stopped leaving yellow debris on the bottom of each well. The well that had the most debris was B1. B1 had a ratio of 1:2 one drop of Pb(NO₃)₂ and 2 drops of KI. The five different ratios were 1:2, 1:1, 2:1, 5:1 and 1:5 that is the order of the most debris going from greatest to least. The Ca(NO₃)₂ and Na₂C₂O₄ did the same thing except that the mixture was grayish white and the ratios were different. The ratios were 2:1, 1:1, 1:2, 1:5 and 5:1 going from most to least debris.

Conclusion

          So what I learned from this experiment is that most reactions have a limiting reaction. A limiting reaction is when two or more compounds react together and one of the compounds gets consumed before the other those limiting the reaction.
