A double bond Breaks and something else is added on.
When a molecule looses water to join together. Eg Glucose
Using water to break a molecule down. Going from larger molecules to smaller molecules, Eg Hydrolysed starch molecules are smaller than ordinary starch molecules.
When a more reactive metal displaces a less reactive metal out of a solution of its own ions.
A combination of an oxidation and reduction reaction.
When a metal looses electrons.
When a metal gains electrons.
When two liquids combine together to form a solid in a liquid. The solid can then be filtered from the liquid by filtration.
The splitting of an ionic compound which is molten or aqueous by using electricity.
Glusocse and oxygen react together with yeast to form carbon dioxide, water and ethanol.
When an alcohol is distilled to increase the alcohol concentration.
Seperating liquids by boiling points.
When a plant makes its own food.
6CO2 + 6H2O ---> C6H12O6 + 6O2
How an animal releases energy from food.
C6H12O6 + 6O2 ------> 6CO2 + 6H2O
Forming a neutral product by:
Adding an acid and an alkali together to make to neutral product.
A neutral solution is added to an acid or an alkali to make the pH closer to 7.
When fuel and oxygen combine together to form carbon dioxide water and energy.
The oxidation of a metal.
A covalent molecule made up of Carbon and Hydrogen.
A family or hydrocarbons with the same general formula and similar chemical properties.
Hydrocarbons with the same molecular formula, but different structural formula. Eg butene and cyclobutane.
Elements with the same atomic number, but different mass number.
Between two or more metals or non metals to achieve a stable outer electron shell.
They do this due to a common attraction for the positively charged nucleus.
Bonding between a metal and a non metal.
They combine due to sharing pairs of electrons.
They can conduct electricity when molten or aqueous
The bonding between two or more metals. They have high melting and boiling points and can conduct electricity in any state.
