The concentration formula is concentration = mass of solute ÷ volume of solution, measured in g/dm³. The Calculating Mass of Solute in Solutions notes cover this in full.
NPK fertilisers are formulations of salts containing nitrogen, phosphorus and potassium compounds, used to improve plant growth and agricultural productivity. The NPK fertilisers and their importance notes cover this in full.
Transition metals have three key features: they form ions with different charges, many of their compounds are coloured, and many transition metals and their compounds are useful catalysts. The Introduction to Transition Metal Properties notes cover this in full.
Percentage yield = (actual mass ÷ theoretical mass) × 100. The Calculating Percentage Yield and Theoretical Mass notes cover this in full.
Galvanising is coating iron or steel with a thin layer of zinc to prevent rusting. The Sacrificial Protection and Galvanising notes cover this in full.
The Mr of ethanol, C₂H₅OH, is 46. The Calculating and Applying Atom Economy notes cover this in full.
The concentration of a solution is measured as mass per unit volume, in g/dm³ or g/cm³. The Calculating Mass of Solute in Solutions notes cover this in full.
Corrosion is the destruction of materials by chemical reactions with substances in the environment, measured by mass loss or structural damage over time. The Understanding Corrosion and Rusting Experiments notes cover this in full.
