Presentation Transcript

  1. What do you think happened to cause the changes in the chemical reaction we did last class? Warm up

  2. Some type of chemical reaction Warm up answers

  3. Complete lab report from previous lab Today’s activities

  4. Introduction • Methods • Results • Conclusion Lab report

  5. Introduction • Question – What is the reaction between these chemicals • Hypothesis – what you thought would happen based on your background info search • Background information – information about the chemicals involved in the reaction Lab report

  6. What you did and how you did it methods

  7. Figure 1 = a data table • Figure 2 = a diagram of the chemical reaction • Figure 3 = a picture of the chemical reaction results

  8. conclusion A. no visible reaction B. Pb(NO3)2 + CuSO4 PbSO4 (s)+ Cu(NO3)2 C. CaCl2 + CuSO4 CaSO4 (s) + CuCl2 But we observed no visible reaction…

  9. All three reactions are double replacement reactions. • However, the solubility rules explain why some form precipitates and others do not. conclusion

  10. How did the blue color of the first chemical effect your observations of the reactions in this experiment? • Think of a creative way to relate what you learned in class today to something that interests you. Cool down
