Magnesium Oxide Vs. Magnesium Chelate | Healthy Living
30/9/2017· Magnesium oxide and magnesium chelate are very similar, as far as what they are used for. Magnesium is a very important mineral for our bodies, and though we can get sufficient magnesium through proper diet, many do not eat well and need extra magnesium.

GCSE CHEMISTRY - Strong and Weak Acids have Different …
Acids and Alkalis Strong and Weak Acids have Different Reaction Rates. Magnesium will react with an acid and make hydrogen gas. The more concentrated the acid, the faster the magnesium will react and you will see bubbles of hydrogen being produced more quickly.
The increase in mass is due to the fact that oxygen from the air has coined with the magnesium to make magnesium oxide, MgO. The chemical equation, Mg + O 2 MgO shows this reaction but it needs to be balanced to make 2Mg + O 2 2MgO.

Heating a reaction mixture speeds up the rate of the reaction. Since magnesium is more active than copper it is more likley to be the reaction that occurs at room temperature and pressure. Copper, being less active than magnesium, is more likely to have the slower reaction rate and therefore is more likley to require heat to speed up the rate of reaction.
