Use bromine water (Br2) or acidified permanganate (H+/MnO4-) With permanganate: add the permanganate to the alkane and no reaction will occur, add the permanganate to the alkene and you will form a diol the solution will also turn from purple to colourless. With bromine water: add the bromine water to the alkane (plus you need sunlight) and you get a substitution reaction, this is a slow reaction. Add the bromine water to the alkene and you get an immediate addition reaction (this one does not need sunlight). When bromine water reacts with an alkene it is decolourised, the reddish brown bromine water turns from brown to colourless. This is because alkenes are unsaturated and contain a carbon to carbon double bond. If you did the bromine water test in a dark place say a cupboard then the alkene would decolourise but the alkane wouldn't because it needs UV/sunlight in order to react. in practice the cupboard is not necessary as the speed of decolourisation is so much faster with the alkene.

The answer is simple: flammability involve a chemical change.
A simple sugar.
Corroding is erosion by chemical action, to keep it simple.

The molecule is Methane.It ia an alkane
Here are some sentences.His hard work will distinguish him from the other employees.How will you distinguish Uncle Paul from the other clowns?
This is a simple sentence using the words "chemical formula".
Bromine is simple covalent and exists as diatomic molecules. There are only very weak forces between the diatomic molecules and these are easy to break.

Both methane and carbon dioxide are green house gases (GHGs) that contribute to global climate change. Methane is a simple alkane with the chemical formula CH4 (one atom of carbon and four atoms of hydrogen). Carbon dioxide has the chemical formula CO2 (cone atom of carbon and two atoms of oxygen). Both methane and carbon dioxide are gases, and each has both biological and non-biological sources in nature.
