H₂O or H₂SO₄? | Chemical Formula Quiz
Test your chemical formula knowledge
Poor little Johnny,
Johnny ain't no more,
For what he thought was H₂O,
Was H₂SO₄.
Mixing up H₂O and H₂SO₄ might seem like a rookie mistake, but in the world of chemical formulas, one wrong letter can spell disaster (just ask poor Johnny). Whether you’ve still got school chemistry buried somewhere in your head or simply love the elegance of a well-balanced equation, this quiz is here to test your formula know-how.
From fizzing acids to everyday compounds hiding in plain sight, I'm covering it all. Dive in, double-check your formulas, and see if you really know your HCl from your CH₄. Just don’t drink anything without reading the label first… ⚗️๐ฅ๐ฌ
