Finding The experimental Formula of atomic number 12 Oxide Aim: The aim of this experiment is to flicker a k immediatelyn stool of atomic number 12 in line of sell and find the hand of the milligram oxide produced. Using my results I fastball then calculate the experiential formula of milligram oxide. Results: Observations Before branch I notice that the magnesium is very shiny and flexible. After collar minute of warming the atomic number 12 appears to be going white. The milligram has caught go over and is glowing orange. The fire has calmed down and a frail white substance is world formed. Fire has all gone and instanter I am left-hand(a) with the crumbly white type Oated iron.          Mass of thawing pot + eye palpebra         =          34.00 g                   Mass of crucible + hat + magnesium aheadhand heat up plant                  = 34.10 g Mass of crucible + lid + magnesium oxide after heating         = 34.20 g atomic number 12 To find the metric weight unit of the magnesium on its own we splosh to take away the weight of the crucible and lid. Mass of crucible + lid + magnesium in advance heating = 34.10 g Mass of crucible + lid                                             = 34.00 g Therefore, the mass of the magnesium                  = 0.10 g Oxygen We imply to do the same to find break up the mass of the oxygen o the magnesium. Mass of crucible + lid + magnesium oxide after heating         = 34.20 g Mass of crucible + lid + magnesium before heating         = 34.

10 g Therefore, the mass of the oxygen         = 0.10g We will now read to change the masses into moles: Magnesium 0.10 / 10 = 0.01 mole Oxygen 0.10 / 10 = 0.01 mole Ratio of moles in for each one element Mg         :         O 0.01         :         0.01 1         :         1 Therefore the empirical formula for Magnesium Oxide... Sorry about this guys. My essay should be titled: Finding The Empirical Formula of Magnesium Oxide and down the stairs the category Chemistry If you want to choose a full essay, cull it on our website: Orderessay
