What do you think happened to cause the color change in the chemical reaction we did last class? Warm up
Some type of chemical reaction Warm up answers
Complete lab report from previous lab Today’s activities
Introduction • Methods • Results • Conclusion Lab report
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
What you did and how you did it methods
Figure 1 = a data table • Figure 2 = a diagram of the chemical reaction • Figure 3 = a picture of the chemical reaction results
Pb(NO3)2 + 2 KI ==> PbI2¯ + 2 KNO3 conclusion
A metal always replaces a metal, a nonmetal always replaces a nonmental. • Therefore this reaction occurs as a double replacement reaction conclusion
Why do you think it is important to understand the difference between metals and nonmetals? • Think of a creative way to relate what you learned in class today to something that interests you. Cool down
