Hey everyone so we are given this balanced reaction in which 27 .3 gram of iron react with 45 .8 gram of oxygen.
00:09
So how many grams of iron three oxide are produced in this reaction? so this is the reaction in which 4 mol of iron react with 3 mol of oxygen and they can produce 2 mole of iron 3 oxide or ferric oxide.
00:28
Let us see the data given.
00:30
So we are given much.
00:30
Mass of iron 27 .3 gram and mass of oxygen 45 .8 gram.
00:38
So when data of more than one reactant is given, first convert all the data into mold, then divide the mole of reactant with the respective stockumentary coefficient.
00:48
Now molar mass of iron 55 .845 gram per mole, molar mass of oxygen, 32 gram per mole, and molar mass of fe2 -03, that means ferric oxide, 159 .69 gram per mole.
01:02
And the mass of iron 3 oxide which mean mass of ferric oxide or f2 .03 that we have to find in this question so let us first find out the number of moles of each reactant so number of moles that is equal to mass divide by molar mass so moles of iron that is equal to mass of iron divide by molar mass of iron so on solving we get the value 0 .488 moles of iron now molts of oxygen that is equal to mass of oxygen divide by molar mass of oxygen so on solving we get 1 .43 mole now number of mole upon stockometric coefficient in case of iron as stoichi metric coefficient of iron that is 4 and the stockometric coefficient of oxygen that is 3 so number of mole upon stockometric efficient in case of iron this value comes out to be 0 .122 and number of mole upon stockometric efficient in case of oxygen this value comes out to be 0 .476 so clearly number of molapone stockometry coefficient of iron is less than that of number of molapone stockometry coefficient of oxygen so therefore in this reaction iron is the limiting reactant or limiting reagent in this reaction because the reactant having minimum ratio will be the limiting reactant the limiting reactant in a chemical reaction is a reactant that is totally consumed when the chemical when the chemical reaction is completed limiting region determine how much product is made and it is available in less quantity than required...
