Exothermic = A reaction that transfers energy to its souroundings therefore the temperature of the sourounding increases (gets hotter). Can you think of an example? E.g. combustion, neutralisation. As hea...

Firstly we must use the periodic table to look at the number of protons (11) contained within a sodium atom. This tells us how many electrons are contained within the shells of that atom as these two are ...

Increasing acid concentration- increased number of reactant particles means they are more crowded so there is a greater chance of the particles collidingIncreasing temperature- reactant particles have mor...

Increasing the concentration of a reactant is the same as increasing the concentration of squash- there are more particles in a solution and in a given space. More particles mean that there is a greater c...

Alkane's are formed from carbon and hydrogen atoms, a compound known as a hydrocarbon, in single bonds. Alkenes are also hydrocarbons, but contain a double bond. In both compound...
