How do you feel today?

😒🙁😐🙂😃

TEMPLATE

• I will know the order of the metal reactivity series.
• I will understand why it is unsafe to add a highly reactive metal to an acid.
• I will be able to carry out displacement reactions to determine a metal's reactivity.

The Metal Reactivity Series

TEMPLATE

Work in groups: Write the observations for each of the following reactions

Demo 1 - for the MOST REACTIVE METALS

Reaction of metals with cold water

2K(s) + 2H₂O (l) → 2KOH (aq) + H₂(g)

2Na(s) + 2H₂O (l) → 2NaOH (aq) + H₂(g)

2Li(s) + 2H₂O (l) → 2LiOH (aq) + H₂(g)

Ca(s) + 2H₂O (l) → Ca(OH)₂ (aq) + H₂(g)

TEMPLATE

Work in groups: Write the observations for each of the following reactions

Predict - for the MODERATELY REACTIVE METALS

Reaction of metals with steam

Mg(s) + H₂O (g) → MgO (s) + H₂(g)

Zn(s) + H₂O (g) → ZnO (s) + H₂(g)

3Fe(s) + 4H₂O (g) → Fe₃O₄ (s) + 4H₂(g)

TEMPLATE

Work in groups: Write the observations for each of the following reactions

Demo 3 - for the MODERATELY REACTIVE METALS

Reaction of metals with dilute acids

Mg(s) + 2HCl (aq) → MgCl₂ (aq) + H₂(g)

2Al(s) + 6HCl (aq) → AlCl₃ (aq) + 3H₂(g)

Zn(s) + 2HCl (aq) → ZnCl₂ (aq) + H₂(g)

Fe(s) + 2HCl (aq) → FeCl₂ (aq) + H₂(g)

Experiment - for the LEAST REACTIVE METALS

Reaction of metals through displacement reactions

Based on the previous activity, 

which is the most reactive metal? 

the least reactive metal?

TEMPLATE

Presents a new problem or scenario that requires students to apply their knowledge. For instance, after studying ecosystems, the teacher might ask students to explore the effects of an oil spill.
