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 one or more electrons...

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 Pressure, surface ar...

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 (6.02x10 23 Avogadro’s number). We can find out how much this is by looking at the re...
