- No reaction
6.
Chlorine meets potassium bromide solution. What forms, Milo?
- No reaction
- KCl₂ and Br
- KCl and Br₂
7.
Will iodine replace bromine in sodium bromide solution, Noah?
- Yes: iodine is heavier
- No: iodine is less active
- Yes: iodine is more active
8.
Which halogen is the most active in the series, Pia?
- Bromine
- Fluorine
- Iodine
9.
Zinc replaces copper, and copper replaces silver. Which order runs from most to least active, Tala?
- Zinc, copper, silver
- Silver, copper, zinc
- Copper, zinc, silver
10.
A metal bubbles in dilute acid but not in cold water. Where does it sit on the ladder, Zee?
- Above potassium, at the top
- Below hydrogen, above copper
- Below sodium, above hydrogen

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.
