AQA svs docshort severnvale - C3 Chemistry keywords
| Question | Answer |
|---|---|
| Activation energy | Minimum energy required for a reaction to happen |
| Alcohol | Contains the -OH functional group |
| Alkali metal | Group I of the Periodic Table |
| Ammonia | Made in the Haber Process |
| Atomic number | Number of protons or electrons |
| Atomic structure | Arrangement of electrons |
| Atomic Mass | Number of protons and neutrons |
| Biofuels | Fuels made from biomass |
| Bond energy | Energy required to break a bond |
| Burette | Used to precisely dispense a volume for titrations |
| Calorimeter | Used to measure energy changes in reactions |
| Carboxylic acid | Contains the functional group -COOH |
| Catalyst | Lowers activation energy and increase rate of reaction |
| Chlorine | Added to water to disinfect |
| Closed system | Where no products, reactants |
| Concentration | The amount of a chemical in solution |
| Displacement | Where a more reactive Halogen knocks a less reactive one out of a compound |
| Endothermic | Energy is absorbed from the surroundings – temperature decreases |
| End-point | The point at which exactly the right quantities of acid and alkali have reacted |
| Equilibrium | Balance between reactants forming the products and products re-forming the reactants |
| Esters | Contains the functional group –COO- |
| Ethanol | An alcohol that has 2 Carbon atoms and is found in alcoholic drinks |
| Exothermic | Energy is released to the surroundings – temperature increases |
| Flame test | Determines the presence or absence of positive ions |
| Fluoride | Added to drinking water to help prevent tooth decay |
| Functional group | Gives a ‘family’ of organic compounds their characteristic reactions |
| Group | Vertical column in Periodic Table |
| Haber process | Chemical process that forms Ammonia when Nitrogen and Hydrogen react |
| Halide | An Halogen that has gained an electron to form an ionic compound |
| Halogen | Group 7 of the period table – poisonous, non-metals |
| Hard water | Can be temporary or permanent. Due to dissolved ions (Ca2+ or Mg2+) |
| Homologous series | Family of compounds that have the same functional group |
| Indicator | Used to determine the end-point of Acid/Base reactions |
| Ion-exchange | Where Ca2+ or Mg2+ ions are replaced with Na+ from a resin |
| Non-renewable | Takes a long time (millions of years) to replace |
| Optimum | The maximum amount you can achieve |
| Oxidised | Oxygen is added either by chemical means or by action of microbes |
| Permanent hardness | Hardness caused by Mg and Ca sulfate. Cannot be softened |
| Pipette | Used to dispense an exact volume of solution |
| Precipitate | When an insoluble solid forms in solution |
| Qualitative | Determines the presence or absence of an ion in a solution |
| Quantitative | Determines the exact amount (concentration) of an ion in a solution |
| Rate | How fast a chemical reaction proceeds |
| Renewable | When a resource can be replaced quickly (e.g. biomass) |
| Reversible reaction | Reactants form products and products form reactants |
| Scale | Insoluble precipitate of calcium or magnesium carbonate |
| Scum | The reaction of soap with calcium or magnesium ions |
| Soft water | Water that does not contain calcium or magnesium ions |
| Softening | Removing calcium or magnesium ions from water |
| Strong acid | An acid where the H+ is completed ionised (dissociated) |
| Temporary hardness | The portion of total hardness that can be removed by boiling |
| Titration | Technique to work out exact volumes of acid and alkali that react exactly |
| Transition metal | Contains a sub-shell of electrons |
| Water filter | Removes impurities from water |
| Weak acid | An acid where there is not complete dissociation |
| Yield | The amount of product made in a reaction |
| Group | Vertical column in the Periodic Table |
| Period | Horizontal row in the Periodic Table |
