Balanced equation is given by

\\ \rm\Rrightarrow 4Fe+3O_2\longrightarrow 2Fe_2O_3

On both sides

  • Fe=4
  • O=6

Hence balanced

Now

  • 3mols of O_2 produces 2 mol Fe_2O_3
  • 1 mol O_2 produces 2/3=0.6mol Fe_2O_3

Moles of O_2:-

  • 17/32= 0.5mol

Moles of Fe_2O_3;

  • 0.5(0.6)=0.3mol

Mass of Fe_2O_3:-

  • Moles (Molar mass)
  • 159.7(0.3)=47.91g

64g of sulfur dioxide (SO2) contains 32g of oxygen. Calculate how much sulfur it contains?
KengaRu [80]
Mass of SO2 = mass of sulfur+ mass of oxygen
⇒ 64 g= mass of sulfur+ 32 g
⇒ mass of sulfur= 64 g-32 g
⇒ mass of sulfur= 32 g.

There is 32 g of sulfur in 64 g of SO2~

If the oxidation state of H is +1 and O is -2, what is the oxidation state of C in C2H4O?
Sedbober [7]

Answer:

-1

Explanation:

According to this question, the oxidation state/number of H and O in C2H4O is +1 and -2 respectively.

The oxidation state of carbon in the compound can be calculated thus:

Where;

x represents the oxidation number of C

C2H4O = 0 (net charge)

x(2) + 1(4) - 2 = 0

2x + 4 - 2 = 0

2x + 2 = 0

2x = -2

Divide both sides by 2

x = -1

The oxidation number of C in C2H4O is -1.
