Balancing Chemical Equations

Description

Teaches the law of conservation of mass by balancing two chemical equations step by step. Shows atom-count tracking on both sides of the equation, then demonstrates adding coefficients to balance H₂ + O₂ → H₂O and CH₄ + O₂ → CO₂ + H₂O.

4	H₂+O₂ balanced	~7s	Add coefficient 2 to H₂ and H₂O, show counts match
5	Atom counter check	~5s	Green checkmarks for H and O counts
6	CH₄+O₂ unbalanced	~6s	Second equation unbalanced
7	CH₄+O₂ balanced	~7s	Add coefficients, show balance
8	Outro	~3s	Summary
