When an acid and a base react it is known as a “neutralisation reaction”. Whenever we balance an eqaution you have to change the nuer of molecules used represented by the big nuers before a molecule e.g 2HCl. This is because, by multiplying the required number of moles to the molar mass of the substance, we easily acquire the mass that must be weighed out for the substance.
