Mole concept
ssssss:
See this reaction 2Fe2S3 + 6H2O + 3O2-------->4Fe[OH]3 + 6S
Now if we got 1,2,3 moles of Fe2S3,H2O and O2 respectively.How much moles of Fe[OH]3 will be formed?
I know the way to solve the equation.That is equation will proceed it this way
2Fe2S3 + 6H2O + 3O2-------->4Fe[OH]3 + 6S
1-2/3... 0 ...3-1 ...2x4/3 ..2
The limiting reagent is H2O so 1.43 moles of Fe[OH]3 will be formed leaving behind 0.33 moles of Fe2S3 and 2 Moles of O2.
Now i want to know whether this reaction will proceed as Fe2S3 and 02 are still left?
movies:
The reaction requires water in order to give the products listed, right? So if there is no more water, the reaction can't proceed further.
ssssss:
You mean to say,
Fe2S3 + O2------>No reaction
movies:
Yup.
According to the equation in the problem water is necessary.
This doesn't preclude some other sort of reaction, however.
