The image on the left has been split in half to reveal the five spherical nodes that make up the 5s orbital. The nodal structure of the 5s-orbital is seen in the shape on the right. The higher s-orbitals ( 6s and 7s), while still spherical, are more complicated since they feature more spherical nodes.
The total charge of a compound must be zero. So the Y ion has charge of -2. Then the charge of X ion+(-2)*2=0. So the charge of X ion is +4.
Answer:
The third one makes the most sense
Answer:
The offspring are all black eye colored.
Explanation:
Since we have genes BB for black eye color and genes bb for brown eye color, crossing the genes, the resulting genotypes in the offspring is Bb, Bb, Bb and Bb. We note that all the genes have the dominant B gene. Since the black eye color dominant gene is present in all the offspring, the offspring are thus all black-eye colored.
So, If you will cross a parent with black eye color (BB) and the other is
brown eye (bb), the offspring are all black eye colored.
