Acid Reactions and Combustions Flashcards
Chemical reaction
A process in which one or more substances are changes into others by their atoms being rearranged.
Salt
The substance formed when an acid reacts with a base
Hydrogen
The atom present in all acids
Reactivity
How reactive a substance is
Carbonate
A type of compound containing carbon and oxygen
Carbon dioxide
The gas in the air used by plants to make food. It is produced during respiration, by burning fossil fuels or by acids reacting with metal carbonates.
Limewater
A solution used to test for the presence of carbon dioxide.
Indigestion
Disruption of the digestion process often resulting in too much acid being produced
Heartburn
When acid from the stomach irritates the upper digestive tract.
Antacid
A substance that neutralises stomach acid.
Base
A substance that neutralises an acid
Neutralisation
When an acid and an base react to form a salt and water and the resulting product has a pH of 7
Fertiliser
A chemical put on soil to increase soil fertility and allow better growth of crop plants
Misconception
A common idea that people share that is inaccurate
Fuel
A material that is burned to release its energy
Combustion
The process of burning
Fire triangle
A model to show the three things needed for a fire - heat, fuel and oxygen
Exothermic
A chemical reaction in which heat energy is given out
Energy
Something has energy if it has the ability to make something happen when the energy is transferred
Alcohol
A liquid chemical such as ethanol which can be used as a biofuel
Sulfur dioxide
Is produced when sulfur is oxidised during the combustion of some fossil fuels and is one of the main gases that produces acid rain.
Acid rain
Rainwater that is made acidic by pollutant gases e.g. sulfur dioxide.
