The ratio of atoms of potassium to ratio of atoms of oxygen is 2:1
If you look closely at each of the four diagrams you would be able to conclude that
<span>D)
Yes. In B and D. In both cases, there is a net force.
In B, there is a net force to the left; in D there is a net force upward.
In A and C, the forces are in equilibrium both in the horizontal and vertical direction.</span>
Because they do not have the same qualities therefore they are different
Polar Covalent.
This is because both Calcium (Ca) and Carbon (C) are non metals, thus eliminating the ionic option.
It is polar covalent rather than nonpolar covalent due to the fact that the electrons in a polar covalent bond are shared unequally while those in a nonpolar bond are shared equally.
This can be determined by looking at the amount of valence electrons; if the electrons cancel each other out, it is shared equally. If not, it is shared unequally.
Hope this helps!
