Answer:
(A) II only
Explanation:
<em>If a compound has a number of individual dipoles, then:
</em>
<em>
(I) It is polar overall.</em> FALSE. If the individual dipoles cancel each other (as it happens in a symmetrical molecule), the net dipole moment is zero.
<em>(II) There is an electronegativity difference between the bonded atoms.
</em> TRUE. If the difference in electronegativity between the elements is higher than zero and lower than 1.7, the bond is polar covalent.
<em>(III) it is ionic.</em> FALSE. If there is a number of individual dipoles, the bonds are most likely to be covalent.
<em>(IV) It doesn't have resonance.</em> FALSE. There is no relation between the resonance and the polarity of the bonds.
I believe the correct answer from the choices listed above is option 2. From the balanced equation, the energy is absorbed as the bonds are broken. Energy is needed to be supplied for the bonds to be broken.
Hope this answers the question. Have a nice day.
Answer:
The weight percent of NaCl in the container is 21.5%
Explanation:
Given that,
Mass of NaCl = 168.90 gram
Mass of water = 616.00 grams
We need to calculate the weight percent of NaCl in the container
Using formula of percentage of weight
Put the value into the formula
Hence, The weight percent of NaCl in the container is 21.5%
