Practice and Revision - Language of Chemistry
Let us practise and revise what we learned about language of chemistry. The language of chemistry uses symbols, formulas, and balanced equat
Core concept
A chemical formula shows the elements and their ratio in a compound, like CO₂ showing one carbon and two oxygen atoms.
How it works
A balanced chemical equation has equal numbers of each type of atom on both sides, following the law of conservation of mass.
Why it matters
For example, 2H₂ + O₂ → 2H₂O is balanced, with 4 hydrogen and 2 oxygen atoms on each side.
Key detail
Understanding chemical language allows precise communication about substances and reactions among scientists worldwide.
