Answer:
The law says the sum of all forms of energy is constant :)
In determining the boiling point
of solutions, always take note of the number of ions that will dissociate in
the solution. It does not depend on the nature of the substance. The greater
the number of ions dissociated, the greater is the boiling point of the solution.
To determine if the compound is an ionic compound, heat it up until the compound reaches its melting point and become molten. Use the molten form to set up an electric circuit and see if the compound will conduct electricity. If the compound conduct electricity then it is an ionic compound. If it does not conduct electricity, it is not an ionic compound. Ionic compounds usually conduct electricity in their molten forms.<span />
<span>When a strontium atom loses two electrons, it becomes a(n) cation with a charge of 2+.
when any neutral atom loses an electron it becomes cation that is positively charged ions and an ion gets the charge according to the number of electrons loses. And if an atom gains an electron it becomes anion that is negatively charged ions.</span>
Fractional distillation<span> is essentially the same as </span>simple distillation<span>except that a fractionating column is placed between the boiling flask and the condenser. The fractionating column is usually filled with glass or plastic beads. These beads improve the separation between the liquids being </span>distilled<span>.</span>
