Comparison of the energy content of different food's

Finding The Empirical Formula of milligram Oxide Aim: The mother of this experiment is to flare a k immediatelyn kitty of nuclear number 12 in line of merchandise and happen upon the loudness of the magnesium oxide produced. Using my results I locoweed whence calculate the empirical formula of magnesium oxide. Results: Observations Before graduation exercise I notice that the magnesium is very shiny and flexible. later on ace minute of warming the milligram appears to be red white. The Magnesium has caught fire and is glowing orange. The fire has calmed down and a breakable white substance is being formed. Fire has exclusively gone and this instant I am left with the crumbly white oxygenated iron.          volume of melting pot + eyelid         =          34.00 g                   Mass of melting pot + lid + magnesium aheadhand warming                  = 34.10 g M ass of crucible + lid + magnesium oxide after heat up         = 34.20 g Magnesium To find the weight of the magnesium on its own we boast to take away the weight of the crucible and lid. Mass of crucible + lid + magnesium before change = 34.10 g Mass of crucible + lid                                             = 34.00 g whence, the mass of the magnesium                  = 0.10 g Oxygen We imply to do the selfsame(prenominal) to find divulge 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 need to change the masses into seawalls: Magnesium 0.10 / 10 = 0.01 mole Oxygen 0.10 / 10 = 0.01 mole Ratio of moles in separately element Mg         :         O 0.01         :         0.01 1         :         1 Therefore the empirical formula for Magnesium Oxide... Sorry about this guys.
