Arrange these molecules in order of decreasing mass: C​6​H​14​ , NO​2​ , Fe​2​O​3 ​, and CaCO​
babunello [35]

The following is the arrangement of the given molecules in decreasing order of mass: \text{ Fe2O3} > \text{C6H14} > \text{CaCO} > \text{NO2}

<u>Solution:</u>

First inorder to arrange the elements in descending order of their mass we have to calculate the molecular mass of each element. The calculation is as follows:

<u>Mass of C6H14:</u>

C\rightarrow6\times12.01 = 72.06

H\rightarrow14\times1.008 = 14.112

<em>Mass of C6H14 is 86.172</em>

<u>Mass of NO2:</u>

N\rightarrow1\times14.0067 = 14.0067

O\rightarrow2\times15.9994 = 31.9988

<em>Mass of NO2 is 46.0055</em>

<u>Mass of Fe​2​O3:</u>

Fe\rightarrow2\times55.845 = 111.69

O\rightarrow3\times15.9994 = 47.9982

<em>Mass of Fe2O3 is 159.6882</em>

<u>Mass of CaCO:</u>

Ca\rightarrow1\times40.078 = 40.078

C\rightarrow1\times12.01 = 12.01

O\rightarrow1\times15.9994 = 15.9994

<em>Mass of CaCO will be 68.0874</em>

So, the order will be 159.6882>86.172>68.0874>46.0055 which is \text{ Fe2O3} > \text{C6H14} > \text{CaCO} > \text{NO2}

Explain what makes a covalently bonded molecule polar. Use the molecules of CH4 and CH3F as examples in your explanation.
RideAnS [48]

Answer:

See explanation

Explanation:

The magnitude of electronegativity difference between atoms in a bond determines whether that bond will be polar or not.

If the electronegativity difference between atoms in a bond is about 1.7, the bond is ionic. If the electronegativity difference is greater than 0.4 and less than 1.7, the bond will have a polar covalent character. Lastly, if the electronegativity difference between the bond is less than or equal to 0.4, the covalent bond is non polar.

The electronegativity difference between carbon and hydrogen is about 0.4 which corresponds to a nonpolar covalent bond hence the molecule is nonpolar.

The electronegativity difference between carbon and fluorine is about 1.5 indicating a highly polar bond. This gives CH3F an overall dipole moment thereby making the molecule polar.
