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

Слайд 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

Слайд 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

Слайд 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

Слайд 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

Слайд 7

Word Equations Part A
A1: Magnesium plus oxygen yields ?
A2: A1 product

plus water yields ?

Слайд 8

Word Equations Part B

B2 Anhydrous Copper (II) Sulfate plus water yields ?

Слайд 9

Word Equations Part C
C1 Iron plus Copper (II) Sulfate yields… ?
C2

Copper plus Silver Nitrate yields… ?
C3 Magnesium plus Hydrochloric Acid yields… ?

Слайд 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

Слайд 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.
