Aim
To determine if the mass increases when we burn the magnesium and change it into magnesium oxide

Research
The type of reaction that took place in this experiment is a chemical reaction and exothermic reaction. It is a chemical reaction because the magnesium and oxygen form to create MgO. The burning of the magnesium is also an exothermic reaction because the magnesium released energy. The law of conservation of mass shows us that mass cannot be destroyed nor created but it can be changed. During the experiment this law is proven because whatever is there at the start is always there at the end and when we did the experiment we burnt a few pieces of magnesium And they didn't lose mass it was just rearranged. It also shows that when a reaction takes place, oxygen can be gained causing gain in weight and also causing a chemical reaction. During the chemical reaction the Mg (Magnesium) becomes MgO (Magnesium Oxide).
