Slide 2

Purpose

To observe 7 reactions

To identify and write formulas for the reactants and products of those reactions

To balance the equations for the reactions

Slide 3

Evidence of Chemical Reaction

Part A

R1 Mg ribbon is ash-like now

R2 Litmus test indicates a base

Part B

R1 Solid turns white, steam comes from test tube

R2 Solid turns blue again

Slide 4

Evidence of Chemical Reaction

Part C

R1 Fe nail is now coated in Cu and the solution has changed from a blue color to a greenish color

Slide 5

Evidence of Chemical Reaction

Part C

R2 Cu metal is now coated with Ag and the solution is beginning to take on a slightly blue tint

Slide 6

Evidence of Chemical Reaction

Part C

R3 HCl solution begins to vigorously bubble when the Mg ribbon is added. Gases are evident as they wisp through the air into the collecting tube; gas is flammable

Slide 10

Instructions

Complete the word equations by predicting the products, use the information you gathered by observation to help in the predictions

Be sure to include the state of the substance for the reactants and products

Classify the reaction

Slide 11

The End

Complete the equations for the reactions

Then you may go finish Part D of the lab instructions. You will need the solubility rules.
