4.
Using the ladder, which metal is the most active, Jun?
- Zinc
- Potassium
- Gold
5.
Using the ladder, can copper replace hydrogen from an acid, Kira?
- Yes: copper is a shiny metal
- No: copper is below hydrogen
- Yes: copper is above hydrogen
6.
In a single replacement reaction, what happens, Milo?
- A compound splits into its elements
- Two compounds swap their partners
- An element replaces one in a compound
7.
Zinc sits in blue copper sulfate solution. What coats the zinc, Pia?
- Yellow sulfur powder
- Gray silver crystals
- Reddish-brown copper
8.
Will magnesium react with zinc nitrate solution, Ren?
- No: magnesium is below zinc
- Yes: magnesium is above zinc
- No: a metal can't replace a metal
9.
Will silver react with copper(II) nitrate solution, Tala?
- Yes: silver is a shiny metal
- Yes: silver is above copper
- No: silver is below copper
10.
Will iron react with dilute hydrochloric acid, Zee?
- Yes: iron is above hydrogen
- No: iron is below hydrogen
- No: acids don't react with metals

Single replacement reactions and the activity series. Every version has 10 questions, and the answer key prints on the second page.

I can use the activity ladder: a metal replaces any metal below it, and metals above hydrogen replace hydrogen from acids.
I can predict products, or no reaction, for a metal in a salt solution or dilute acid.
I can use the halogen order F₂, Cl₂, Br₂, I₂ the same way.
I can rank metals from results and say which particle loses electrons.

Standard: HS-PS1-2

activity series: A list of metals, most active first

single replacement: A + BC → AC + B: a lone element swaps into a compound

more active: Higher on the ladder; replaces the metals below it

no reaction: The lone element is lower, so nothing swaps

spectator ion: An ion that stays the same on both sides, such as sulfate

Your child matched one silver atom to each copper atom. The equation's 2 in front of Ag means two silver atoms per copper atom.

Your child used the 3 in front of Zn but not the 2 in front of Al. Two aluminum atoms make three zinc atoms.

Your child multiplied by 2. Each copper atom makes two silver atoms, so the copper count is the silver count divided by 2.

What is the most common mistake with single replacement reactions and the activity series?

Your child matched one silver atom to each copper atom. The equation's 2 in front of Ag means two silver atoms per copper atom.
