The balanced chemical equation representing the reaction of iron and oxygen is,

4 Fe (s)+ 3O_{2}(g) --> 2 Fe_{2}O_{3} (s)

The coefficients of each reactant and product represents the number of moles of each reactant or product that is required for the complete reaction to take place.

The mole ratio of iron and iron (III) oxide: \frac{4 mol Fe}{2 mol Fe_{2}O_{3}} or \frac{2 mol Fe_{2}O_{3}}{4 mol Fe}

Mole ratio of oxygen to iron (III) oxide: \frac{3 mol O_{2}}{2 mol Fe_{2}O_{3}} or \frac{2 mol Fe_{2}O_{3}}{3 mol O_{2}}

So, the mole ratio of iron (Fe) to oxygen gas is: 4 : 3

Therefore, the correct answer is d) 4:3

How many milliliters of water will it take to fill a 2 L bottle that already contains 1.87 L of water?
Aloiza [94]

Answer:

0.00013

Explanation:

I'm pretty sure. I first subtracted 1.87 from 2. I got 0.13. The conversion from mL to L is 0.001. I multiplied 0.13 and 0.001 and got <u>0.00013 mL.</u>

What type(s) of intermolecular forces are expected between ch3ch2ch2ch2ch2oh molecules?
notka56 [123]

Answer : Hydrogen-bonding, Dipole-dipole attraction and London-dispersion force.

Explanation :

The given molecule is, CH_3CH_2CH_2CH_2CH_2OH

Three types of inter-molecular forces are present in this molecule which are Hydrogen-bonding, Dipole-dipole attraction and London-dispersion force.

  • Hydrogen-bonding : when the partial positive end of hydrogen is bonded with the partial negative end of another molecule like, oxygen, nitrogen, etc.
  • Dipole-dipole attraction : When the partial positively charged part of the molecule is interact with the partial negatively charged part of the molecule. For example : In case of HCl.
  • London-dispersion force : This force is present in all type of molecule whether it is a polar or non-polar, ionic or covalent. For example : In case of Br-Br , F-F, etc

Hydrogen-bonding is present between the oxygen and hydrogen molecule.

Dipole-dipole forces is present between the carbon and oxygen molecule.

London-dispersion forces is present between the carbon and carbon molecule.
