"Chemistry song 11" joke

Chemistry Wonderland
Gases explode, are you listenin'
In your rest tube, silver glistens
A beautiful sight, we're happy tonight
Walking in a chemistry wonderland.
Gone away, is the buoyancy
Here to stay, is the density
A beautiful sight, we're happy tonight
Walking in a chemistry wonderland.
In the beaker we will make lead carbonate
and decide if what's left is nitrate
My partner asks "Do we measure it in moles or grams?"
and I'll say, "Does it matter in the end?"
Later on, as we calculate
the amount, of our nitrate
We'll face unafraid, the precipitates that we made
walking in a chemistry wonderland.
