A 5 mole sample of liquid acetone is converted to a gas at 75.0°C. If 628 J are required to raise the temperature of the liquid
velikii [3]
The total energy required for this conversion is equivalent to the sum of the energies that are used. There are three steps:

1) Heating of liquid acetone
This used 628 J

2) Evaporation of acetone
This used 15.6 kJ or 15,600 J

3) Heating of acetone vapors
This used 712 J

Adding these quantities,

Total energy = 628 + 15,600 + 712

The total energy required was <span>16940 Joules of 16.94 kJ</span>

How many pounds does 1.00 quart of mercury weight? its density is 13.6g/mL
Gala2k [10]
Two steps by inspection 1 qt = 0.25 gallons, 13.6 g/mL = 13.6 kg/L

0.25 gallon x 3.785411784 L/gallon x 13.6 kg/L x 1 lb/0.45359237 kg = 28.374 lb.

Hope this Helps!

A phase is a part of a system with what type of composition?
TiliK225 [7]

Answer:

<u>uniform composition.</u>

Explanation:

A phase is a part of a system with uniform composition.

  • In physics and chemistry , a phase in a physically distinctive form of matter , such as solid , liquid , gas or plasma.
  • A phase matter is characterised by having relatively uniform chemical and physical properities . Phases are different from states of matter.
  • The states of matter (e.g ., solid , liquid , gas ) are phases but matter can exist in different phases and yet be in the same type of matter. For example , liquid mixtures can exist in multiple phases such as oily and aqueous phase.
  • some different types of phases are : solid, liquid,gas , plasma etc.
  • The term phase can also sometime mean describe equilibrium in phase diagram
