Dear students, 1 .3 gram of ferosulfide reacts with 0 .518 mol of h2 co3, carbonic acid, with a yield of 77 .7 percent, how much of ferrous oxide will form as for this balanced equation? here, n is not given, doesn't matter, we need a relationship between fes, h2co3 and feo.
00:25
So, let us see here how much of feroculfide as per the equation reacts with carbonasephylphalphi, carbonic acid.
00:33
Now ferrosulfide here molecular mass 2 multiplied by iron is 56 plus sulfur is 32, 2 multiplied by 56 plus 32, which is equal to this is 8, this is 8, 16, 17, 6 gram.
00:58
Carbonic acid is 1 mole as for the balanced equation.
01:03
Then, 176 gram of ferosulfide reacts with 1 mole of carbonic acid.
01:15
Therefore, we have just 1 .30 gram of ferosulfide will react with how much 1 divided by 176 multiplied by 1 .30, which is equal to approximately 0 .007.
01:44
4 mole of carbonic acid.
01:50
Therefore it clearly shows that carbonic acid is more than the required amount, so fes is the limiting reactant.
01:59
Now we will calculate ferrous oxide from fes.
02:05
So here fas amount is 1 .3 gram...
