Answer:
B - End to end overlap of p overlap
Explanation:
Sigma bonds (σ bonds) are the strongest type of covalent chemical bondSigma bonds are formed by end-to-end overlapping. Sigma bonds can occur between any kind of atomic orbitals;The combination of overlapping orbitals can be s-s, s-pz or pz-pz.
A gene is harder to explain but it is scientifically what decides who you are (what you look like) and a trait is something from how you act to somoyour interested in. Ex. Girl who is a dog lover
The gene decides she is a girl
The trait is that she likes dogs
Explanation:
An ionic equation will be the one in which all the participating species will be present as ions.
The given reaction will be as follows.

Balancing this equation by multiplying
by 2 and
by 3 on reactant side. Whereas multiply KBr by 6 on product side.

Hence, the net ionic equation will be as follows.

As both
and
are spectator ions. Hence, the net ionic equation will be as follows.
