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.
Answer:
Distance: - The distance travelled by a body is the actual length of the path covered by a moving body irrespective of the direction in which the body travels. For example- if a man walks 4 km in east and 3km in north then actual length covered by the man is 4+ 3= 7 km.

Answer:
True
Density = mass/volume
Suppose that a block has a mass of 20 g and a volume of 20 cm^3.
Density = 20 g/20 cm^3 = 1 g/cm^3
Now, you cut the block in half. The half-block has a mass of 10 g and a volume of 10 cm^3.
The density of the half-block is
Density = 10 g/10 cm^3 = 1 g/cm^3
The density stays the same, even though the size of the sample has changed.
Explanation:
Ethanoic acid ionizes in aqueous solutions to form two ions which are 
and 
<h3>Ionization of ethanoic acid</h3>
Ethanoic acid goes by the chemical formula 
.
In aqueous solutions, it ionizes as a monoprotic acid according to the following equation:
A monoprotic acid is an acid that is able to donate only a proton. Hence, ethanoic acid is said to be monoprotic because it ionizes in aqueous solutions to produce a single
