Question

Complete the table using the balanced chemical equation

Answer 1

For 1.2 mol FeS, 1.8 mol O2, 1.2 mol FeO, 1.2 mol SO2
For 5.2 mol SO2, 5.2 mol FeS, 7.8 mol O2, 5.2 mol FeO

Answer 2

First line of the table:

FeS: 1.2mol

`O_(2)`: 1.8moles

FeO: 1.2moles

`SO_(2)`: 1.2moles

Second line of the table:

FeS: 5.2mol

`O_(2)`: 7.8moles

FeO: 5.2moles

`SO_(2)`: 5.2moles

Step-by-step explanation:

1. Take as reference the balanced chemical equation:

`_(2)FeS(s)+_(3)O_(2)(g)=_(2)FeO(s)+_(2)SO_(2)(g)`

2. Take the first quantity given in the table to calculate the quantities of the other compounds using stoichiometry:

- Calculate the number of moles of
`O_(2)`:

`1.2molesFeS*(3molesO_(2))/(2molesFeS)=1.8molesO_(2)`

- Calculate the number of moles of FeO:

`1.2molesFeS*(2molesFeO)/(2molesFeS)=1.2molesFeO`

-Calculate the number of moles of
`SO_(2)`:

`1.2molesFeS*(2molesSO_(2))/(2molesFeS)=1.2molesSO_(2)`

3. Take the second quantity given in the table to complete the other quantities using stoichiometry:

- Calculate the number of moles of FeS:

`5.2molesSO_(2)*(2molesFeS)/(2molesSO_(2))=5.2molesFeS`

- Calculate the number of moles of
`O_(2)`:

`5.2molesSO_(2)*(3molesO_(2))/(2molesSO_(2))=7.8molesO_(2)`

- Calculate the number of moles of FeO:

`5.2molesSO_(2)*(2molesFeO)/(2molesSO_(2))=5.2molesFeO`
