: [[Ethanoic Acid]] + [[Calcium Oxide]] → [[Calcium Ethanoate]] + [[Water]]
: [[Ethanoic Acid]] + [[Manganese Oxide]] → [[Manganese Ethanoate]] + [[Water]]
==Key Stage 4==
===Meaning===
[[Acid + Metal Oxide → Metal Salt + Water]] is the general [[Chemical Equation|equation]] for a [[neutralisation]] [[Chemical Reaction|reaction]] between a [[Metal Oxide]] and an [[acid]].
===About 'Acid + Metal Oxide' Reactions===
: '''[[Acid]] + [[Metal Oxide]]''' [[Chemical Reaction|reactions]] are [[exothermic]] so the there will be a [[temperature]] rise.
: '''[[Acid]] + [[Metal Oxide]]''' [[Chemical Reaction|reactions]] occur when the [[Metal]] in the [[Metal Oxide]] is more [[Reactivity|reactive]] than [[Hydrogen]]. This means the [[metal]] can lose [[electron]]s more easily than [[Hydrogen]] can.
: During an '''[[Acid]] + [[Metal Oxide]]''' [[Chemical Reaction|reaction]] the [[Hydrogen Ion (Chemistry)|H<sup>+</sup> ions]] gain an [[electron]] from the [[Metal]] and [[bond]] with the [[Oxygen]] to [[product|produce]] [[water]].
