Frequently asked questions
What is Topic C7: Practical skills?
Topic C7: Practical skills covers Practical activity skills in GCSE OCR Foundation Chemistry. 12 lessons in 1 subtopic.
What is a chromatogram?
A chromatogram is the pattern of separated substances produced by chromatography, showing spots at different distances from the origin. The Chromatogram Analysis and Rf Values notes cover this in full.
What are examples of endothermic reactions?
Examples of endothermic reactions include thermal decomposition, such as calcium carbonate breaking down into calcium oxide and carbon dioxide, and citric acid reacting with sodium hydrogencarbonate. The Examples and Applications of Energy Transfer Reactions notes cover this in full.
What is combustion?
Combustion is the reaction of a fuel with oxygen that releases energy as heat and light. The Examples and Applications of Energy Transfer Reactions notes cover this in full.
How do you calculate an Rf value?
Rf = distance moved by substance ÷ distance moved by solvent, both measured from the origin. The Chromatogram Analysis and Rf Values notes cover this in full.
What are examples of exothermic reactions?
Examples of exothermic reactions include the combustion of fuels such as methane, oxidation reactions such as iron rusting, and neutralisation of acids and bases. The Examples and Applications of Energy Transfer Reactions notes cover this in full.
What colour is universal indicator at different pH values?
Universal indicator is red at pH 0-3, orange at pH 4-5, yellow at pH 6, green at pH 7 (neutral), blue at pH 8-10 and purple at pH 11-14. The Understanding the pH Scale notes cover this in full.
What factors affect the rate of reaction?
The five factors that affect the rate of reaction are the concentration of reactants in solution, the pressure of reacting gases, the surface area of solid reactants, temperature, and the presence of a catalyst. The What affects how fast reactions happen? notes cover this in full.
What is rate of reaction?
Rate of reaction is how fast reactants are used up or products are formed in a chemical reaction, measured in units such as g/s or mol/s. The What affects how fast reactions happen? notes cover this in full.
