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>
Answer:
They attract or repel other charged objects without touching them.
Explanation:
My chemistry teacher always says like repels like opposite attracts.
<span>I believe that in this
case the controlled parameter is the type of animal that they are observing.

Explanation:
Answer: The mass in grams for a 9.50 carat diamond is 1.9.
Explanation:
Given :
The mass of gemstones and pearls is usually expressed in units called carats.
we have to find mass in grams for 9.50 carat diamond.
1 carat = 200 mg
Thus 9.50 carat=
Also 
Thus 
Thus the mass in grams for a 9.50 carat diamond is 1.9
