Which of the following molecules contains polar covalent bonds?
1 answer:
Answer:
H₂O
Explanation:
Hello,
In this case, polar covalent bonds are identified by looking the electronegativity difference between the bonding atoms, if its less than 1.7 and more than 0.7, thus, for water, H₂O, it turns out:
Thereby, it is polar covalent, whereas the other ones are ionic or nonpolar covalent.

Hello,
In this case, it is firstly necessary to compute the dissolved moles of hydrogen chloride into the water as shown below:
Thus, the molarity is computed as shown below:
Wherein no change in volume is considered, therefore the volume of the solution was the same volume of water.
