Answer: Chemical Formula = COBr₂
Structural Formula = Attached Below
IUPAC Name = Carbonic Dibromide
Common Name = Bromophosgene
As we know Carbon has the tendency to form four covalent bonds, Oxygen can form two covalent bonds and Bromine can form a single bond. Keeping this in mind we can say that in given compound carbon is forming two single bonds with two bromine atoms and a double bond with oxygen atom. Therefore, the valencies of all elements in the given compound are satisfied and completed.

Explanation:
The formula for the entropy associated with a reversible phase change is

1. Calculate q
For a reversible phase change like melting,

2. Calculate ΔS

Answer:
0.4033 M is the concentration of the sodium hydroxide solution.
Explanation:
Mass of potassium hydrogen phthalate = 2.023 g
Molar mass of potassium hydrogen phthalate = 204.22 g/mol
Moles of potassium hydrogen phthalate :
= 

According to reaction, 1 mole of potassium hydrogen phthalate reacts with 1mole of NaOH. Then 0.009906 moles of potassium hydrogen phthalate will recat with:
of NaOH
Moles of NaOH = 0.009906 mol
Volume of NaOH solution = 24.56 mL = 0.02456 L

![[NaOH]=\frac{0.009906 mol}{0.02456 L}=0.4033 M](https://tex.z-dn.net/?f=%5BNaOH%5D%3D%5Cfrac%7B0.009906%20mol%7D%7B0.02456%20L%7D%3D0.4033%20M)
0.4033 M is the concentration of the sodium hydroxide solution.
