Ionic compounds are between metals and non metals, otherwise if it’s a nonmetal with a nonmetal it’s molecular
The molar mass of methylammonium bromide is 111u.
<h3>What is molar mass?</h3>
The molar mass is defined as the mass per unit amount of substance of a given chemical entity.
Multiply the atomic weight (from the periodic table) of each element by the number of atoms of that element present in the compound.
Add it all together and put units of grams/mole after the number.
Atomic weight of H is 1u
Atomic weight of N is 14u
Atomic weight of C is 12u
Atomic weight of Br is 79u
Calculating molar mass of 
=2(1 x3+ 14+12+ 1 x 3 +79) = 111u
Hence, the molar mass of methylammonium bromide is 111u.

Answer: It turns blue litmus red
Explanation:
I just got it right on edge
An acidic solution would turn a blue litmus paper red due to the mobile and free hydrogen (H+) ions. These hydrogen ions affect the colour property of the litmus papers and thus the colour change. A litmus paper dropped into a solution of hydrogen ions turns red to indicate that the solution is acidic.
Answer:
False
Explanation:
The temperature at which a solid melts, known as its melting point is highly characteristic of a compound and element.
The melting point of pure substances, compounds and elements is definite and not varied.
- Melting point is an intensive property of matter.
- It does not depend on the amount of matter present.
- It is an innate or intrinsic property of every matter.
- For example, no matter the volume or mass of water, it will always boil at 100°C, all things being equal.
Therefore, melting point of most solids is characteristic of compounds and elements.
