without having to type equations in this post!! Arrrgggggg

Half equations help us understand the electron transfer process between metals and non-metals. Generally:

* metals lose electrons to form metal ions (cations)

* non metals gain electrons to form non-metal ions (anions)

* hydrogen ions gain electrons to form hydrogen gas.

Using these generalisations, we can write half-equations for the reactions between metals and dilute acids. Half equations must be balanced in terms of atoms and charges.

Ionic equations are created by summing two-half equations so that the number of electrons lost by the metal equals the number gained by the non-metal or hydrogen ion.

Now …….. remember the dot point for this……” construct half equations to represent the electron transfer reactions occurring when metals react with dilute hydrochloric and sulphuric acid”…..in other words you only need to be concerned with half equations associated with metals + Acid………(even though you can do it all reactions of metals 🙂  – you’re such clever chickens!!!!)

Does this help ??? Remember to use that text that holds up the leg of your desk to find some extra examples and questions to practise on………
