Answer:
Ionic Compound
Explanation:
To identify the type of chemical bond in a molecule, look at the atoms that make up the compound. If there are two nonmetals, it is a covalent bond. If the two atoms are metals, it is a metallic bond. If one atom is a metal and the other is a nonmetal, it is an ionic bond. Ionic compounds are also known as salts. You can identify KBr as an ionic compound because potassium is a metal and a salt.

Answer:
The amount of work must be do to rotate the bar magnet is 151.2 J
Explanation:
Given:
Magnetic moment 
Magnetic field 
T
To find work do to rotate the bar magnet,
From the formula of work done in case of magnetic field,
Here 
changes 0 to 180
But 
J
Therefore, the amount of work must be do to rotate the bar magnet is 151.2 J
