Answer:
C.overlapping p orbitals
Explanation:
The atoms which comprises of single bond is formed by sigma bond. Sigma bond is formed by the internuclear overlapping of the atomic orbitals. They are formed due to the head on overlapping of the atomic orbitals. Since, the bond is symmetrical about the internuclear axis, it can rotate without the breakage of the bond.
On the other hand, double or triple bonds contains one or two pi bonds respectively along with one sigma bond. Pi bonds are formed by the sideways overlapping and thus they are non-symmetrical about the internuclear axis and thus it breaks if the bond is being rotated.
Thus the answer is:- C.overlapping p orbitals
Answer:
b
Explanation:
carbonated and dioxedi mixed up
In bleaching a stain, you see that the stain fades, and doesn't come back, which indicates that it has undergone a change.
Buring a match, you would see the ashes, and that it cannot be it's original substance again.
In rusting of an iron nail, the nail cannot be unrusted easily, which indicates that it has been through a chemical reaction.
Na-24 and Na-23 have the same number of atoms=11, different neutrons(13 and 12),different mass number(24 and 23)
<h3>Further explanation
</h3>
The elements in nature have several types of isotopes
Isotopes have the same number of protons and having a different number of neutrons.
So Isotopes are elements that have the same Atomic Number (Proton)
number of atoms = 11
mass number = 23
number of neutrons=23-11=12
number of atoms = 11
mass number = 24
number of neutrons=24-11=13
