115 grams total
15/115= 13%
109/115= 87%
.13x 16.4= .277
.87x 86.5= 75.255
75.255+.277= 75.532 deg C
or 75.5 as 3 significant digits
True
Explanation:
Ionic compounds are chemical compounds that dissociates into positive and negative ions and are globally neutral due to the charge balance. They are made up of metals and non-metals.
- Ionic bonds are formed between two kinds of atoms having a large electronegativity difference.
- It is usually between metals and non-metals.
- The formation of this bond type involves the transfer of electrons from the less electronegative atom such that the two kinds of atoms now have completely filled outer shell like the noble gases.
- This transfer makes the metal positively charged while the non-metal becomes negatively charged.
- The atoms forms ions that are oppositely charged.
- The charges are balanced out leaving a net neutral compound.
- The electrostatic force of attraction between these ions is the ionic or electrovalent bond.
