There is a range of places to search for existing data that may be suitable to use in your research. It can save time to reuse a dataset, especially where data is expensive to collect, or where ...

Oxidation reactions involve the process where a substance, for example an alcohol, undergoes a chemical change to form a more oxidised product, such as an aldehyde or carboxylic acid. To oxidise ...

Esterification is a type of condensation reaction as water is a byproduct. Esterification reactions are a fundamental type of organic reaction where an alcohol reacts with a carboxylic acid to form an ...

Addition reactions involve two or more reactants combining to form a single product, often seen with alkenes. These reactions create more complex organic molecules, which are essential in the ...

There are five main factors that influence the rate of chemical reactions. These are temperature, surface area, concentration, pressure and the use of a catalyst. These are explored in more detail ...

Carbon atoms are implied at the ends and intersections of the lines in a skeletal structure. Each line represents a bond between two atoms, typically carbon-carbon bonds. Each vertex or end of a line ...

Energy value refers to the amount of energy supplied by a certain amount (e.g., per gram, per 100 grams) of food. Food provides the energy needed for essential functions in the body. Three key ...

When scientists evaluate a new fuel, one important measure is its heat of combustion, which indicates the amount of energy released when a specific amount of the fuel undergoes complete combustion.

The coefficients in a balanced equation represents the molar ratio of the amounts of reactants and products involved in the reaction. In thermochemical equations, the coefficients also indicate the ...

Boiling point is the temperature at which a liquid's vapour pressure equals the external pressure, causing it to change into a gas. Melting point is the temperature at which a solid becomes a liquid.

Chemical reactions occur in a variety of situations with a wide range of different reaction types. Some chemical reactions occur extremely quickly, such as the explosion of a firework. Other chemical ...

In organic chemistry, reaction pathways refer to the series of steps that transform reactants into products. The efficiency of these pathways is a key consideration, as it determines how effectively a ...
