The chemical equation is:2 Mg + O2 = 2 MgO
Use a magnet to lift out the iron filings.
thermal
Umm...a solid chemical that's been ground to a fine powder?
if you dont know this your an idiot
When baking powder is used in baked products it produces carbon dioxide
zinc(II) oxide
The chemical equation is:S + O2 = SO2
When manganese dioxide is heated with aluminium powder, the following reaction takes place: These displacement reactions are highly exothermic. The amount of heat evolved is so large that the metals are produced in the molten state. On the other hand when manganese is heated with aluminum oxide no reaction takes place as aluminum is more reactive than manganese and is placed higher in the activity series.
The iron fillings are attracted by the magnet and separated from the sulphur powder.
Fe + S = FeS
you use a magent
Powder Coating I think
NaHCO3 + HCl = CO2 + H2O + NaCl
If you put the magnet near the iron fillings, they will be drawn out by the magnetic pull of the magnet.
Calcium carbonate thermally decomposes when heated to form calcium oxide powder and carbon dioxide gas. The word equation: calcium carbonate --> calcium oxide + carbon dioxide As a symbol equation: CaCO3 --> CaO + CO2
The chemical equation is:2 Mg + O2 = 2 MgO
