Answer:
Empirical formula is C3H3O
Molecular formula C9H9O3
Explanation:
From the question given, we obtained the following data:
Carbon = 63.15%
Hydrogen = 5.30%
Oxygen = 31.55%
We can obtain the empirical and molecular formula by doing the following as illustrated in the attached file. Please see attachment for explanation.
Ionic would be the answer
Answer:

Explanation:
Hello!
In this case, considering the Gay-Lussac's law which describes the pressure-temperature behavior as a directly proportional relationship by holding the volume as constant, we write:

Whereas solving for the final temperature T2, we get:

Thus, we plug in the given data (temperature in Kelvins) to obtain:

Best regards!
Answer: 
Explanation:
Elevation in boiling point is given by:

= Elevation in boiling point
i= vant hoff factor = 3 (number of ions an electrolyte produce on complete dissociation)

= freezing point constant = 
m= molality

Weight of solvent (water)= 1.000 kg
Molar mass of solute
= 142 g/mol
Mass of solute
= 175.0 g


Thus the boiling point of water when 175.0 g of
, a strong electrolyte is dissolved in 1.000 Kg of water is
