Mg + F2 ---> MgF2
Is it a chemical change.
Yes. Because there is a chemical change
Typical mixing have not a chemical ecuation.
They will NOT react, so no chemical equation. (Mixing is NOT chemical, besides these two won't mix homogeneously!
Magnesium Oxide and Magnesium Carbonate are very different, Magnesium Oxide is Magnesium fused with Oxygen whereas Magnesium Carbonate is Magnesium fused with Carbon and Oxygen. The suffix "ate" means that an oxygen atom is involved. This added element (carbon) means that there will be a slight change in product. The chemical formula for Magnesium carbonate is MgCO3 whereas Magnesium oxide is MgO. See how there are two extra oxygens and one extra carbon? Add them together and you have CO2 and this is your difference. The difference in mixing magnesium oxide with sulfuric acid rather than mixing magnesium carbonate with sulfuric acid is that sulfuric acid and Magnesium carbonate create CO2 whereas Magnesium Oxide and sulfuric acid do not.
Magnesium hydrochloride
ordinary mixing is a physical change but when you get to heat them products are formed and it is a chemical change.
It depends on what you are mixing it with.
Because you change the composition of the original matter. It is no longer in its original state. Chemical Change- Change in composition; burning, crushing, etc. physical change- changing state, but substance's composition stays same; freezing, boiling, etc
Magnesium nitrate (salt) and water are produced.
when you mix sulphuric acid with magnesium you create a gas called hydrogen.
Sodium dichromate has the chemical formula of Na2Cr2O7. The reaction with HNO3 is balanced as 2 HNO3 + Na2Cr2O7 = H2Cr2O7 + 2 NaNO3.
