acid + hydroxide > salt + water

so this makes Sodium Chloride and water

Relative formula mass is the mass compared  of the compound compared with the mass of atoms of other elements. 
Using the periodic table, the individual Ar (relative atomic mass) can help you find t...

Although both are... 1. Alltotropes of carbon, i.e. both are composed of carbon. 2. Giant covalent structures. Which are composed of non-metal aroms, held adjacently by c...
