Answer:-
b. compound b will show an nh absorption while compound a will not.
Explanation:-
For compound B CH3CH2CH2NH2 there are two N-H bonds present. So it will show NH absorption.
But in compound A CH3CH2CH2N(CH3)2 there are no N-H bonds. So it will not show NH absorption.
Given what we know about lab safety, we can confirm that when dealing with unstable and erratic equipment such as the stirring mechanism, in this case, the best course of action is to deactivate the equipment until further notice.
<h3>Why should we turn off the equipment?</h3>
- The erratic nature of the stirring mechanism is making the entire system unstable.
- When dealing with a hot plate, and heating substances, we need to maintain stability at all times.
- We do this to avoid spills that may cause burns or other unwanted damages.
- Therefore, until we know why the stirring was erratic, we must turn the mechanism off.
Therefore, we can confirm that when dealing with faulty or unstable lab equipment, we must deactivate the equipment immediately in order to preserve our lab safety.

Answer:
Two unlike charged ions.
Explanation:
The positive charge on one and the negative on the other helps form the ionic bond.
Ionic bonding is the complete transfer of valence electron(s) between atoms. In these types of bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion..
Ionic bonding is observed because metals have few electrons in their outer-most orbitals. By losing those electrons, these metals can achieve noble gas configuration and satisfy the octet rule.
