Chemical quantities and practical evidence
Prepared for Owner review · not on saleSS Chemistry · WAEC / NECO and international fit review
What the prepared pack contains
- Reacting amounts: balance, convert, apply the mole ratio and check the controlling reactant
- Chromatography: measurement, matching conditions and justified inference
- Six graduated checks, two Mistake Clinics and supplied-data transfer
Starting knowledge
- Balanced equations and mass-to-mole conversion
- Ratios with stated units
- Chromatogram baseline and solvent-front conventions
Intended outcomes
- Use mole coefficients without incorrectly applying them to grams
- Preserve assumptions such as an excess reactant
- Distinguish evidence of components from proof of identity or purity
A sample of the reasoning
In N₂ + 3H₂ → 2NH₃, 0.45 mol H₂ can produce 0.30 mol NH₃ only when enough N₂ is present. The coefficients relate amounts in moles.
