Which compound most likely contains polar covalent bonds?<br> NaCl<br> AlF3<br> Br2<br> NF3
belka [17]

Answer: The correct answer is NF_3

Explanation:

In NF_3 molecule, there are three bond pairs and one lone pair present in the molecule. In a molecule, lone pair present on the nitrogen atom will have a dipole moment in upward direction where as total dipole moment formed by three fluorine atoms will be more in magnitude and it will be directed in downward direction which means that the net dipole moment will be in downward direction. As shown in image attached.

Hence, covalent bond present between nitrogen and fluorine will become polar in nature.

So, the correct answer is NF_3.

Find the volume of the prism
Andrei [34K]

Answer:

440cm³

Step-by-step explanation:

Area of trapezium base=

\frac{1}{2} \times (a + b) \times h

\frac{1}{2} \times (8 + 14) \times 4

\frac{1}{2} \times 22 \times 4 \\  =  \frac{88}{2}  \\  = 44 {cm}^{3}

Volume=Area or trapezium x Height between trapezium ends

= 44 \times 10 \\  = 440 {cm}^{3}
