Answer:

A = B < D < C

C - S

Cl - Cl

F ← H

Si → O

Explanation:

The polarity of a bond increases with the increase in the difference in electronegativity. The dipole moment is represented with an arrow pointing the more electronegative atom.

A: carbon-sulfur

C - S

ΔEN = |EN(C) - EN(S)| = |2.5 - 2.5| = 0

B: chlorine - chlorine

Cl - Cl

ΔEN = |EN(Cl) - EN(Cl)| = |3.0 - 3.0| = 0

C: fluorine – hydrogen

F ← H

ΔEN = |EN(F) - EN(H)| = |4.0 - 2.1| = 1.9

D: silicon - oxygen

Si → O

ΔEN = |EN(Si) - EN(O)| = |1.8 - 3.5| = 1.7

The order of increasing polarity is A = B < D < C.

Acetaminophen is the active ingredient in Tylenol.
Tomtit [17]

Explanation:

a. Write the molecular formula of the compound.

Acetaminophen contains 8 carbon atoms, 9 Hydrogen atoms, 1 Nitrogen atom and 2 Oxygen atoms.

The molecular formular is given as;  C8H9NO2

b. What is the hybridization state of each C, N, and O atom?

From the image attached;

All the carbon atoms in the benzene ring has hybridization of sp2.

The carbon that is doubly bonded (carbonyl) to the oxygen has hybridization of sp2

The last carbon to the right has hybridization of sp3

The hybridization of nitrogen in the compound is sp3 hbridized.

Oxygen atom in alcohol  is sp3 hybridised

Oxgen in the carbonyl group is sp2 hybridized.

How many moles of Chromium are in 1.410 * 10 ^ 23 atoms of Chromium?
leva [86]

Answer:

<h3>The answer is 0.23 moles</h3>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

n =  \frac{N}{L}  \\

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

n =  \frac{1.410 \times  {10}^{23} }{6.02 \times  {10}^{23} }  \\  = 0.234219...

We have the final answer as

<h3>0.23 moles</h3>

Hope this helps you
