A reaction will occur if two reactants collide with each other with enough energy to overcome the 'activation energy'. The activation energy is the minimum amount of energy the reactant particles need ...

A salt and water (H₂O). H⁺ from the acid and OH^- from the base combine to make water. The salt formed depends on the acid and base counterions, and is usually dissolved in...

Covalent bonds are formed when two atoms share one or more pairs of electrons. These atoms are non-metals, such as Carbon, Oxygen and Hydrogen.

Ionic bonds are formed when an atom gives o...

Temperature, pressure, surface area and concentration all affect the rate of a chemical reaction. 

Temperature makes the particles more energetic and increases the frequency of collisions...

A mole is an amount of an element or compound which contains as many atoms or molecules as is present in 12g of carbon 12 (6.02x10²³ Avogadro’s number).
