Answer:
The boiling point is the temperature at which the vapor pressure equals the pressure of gas.
The normal boiling point is the temperature at which the vapor pressure equals one atmosphere
Explanation:
Many transition metal ions(e.g. in soluble salt solutions) give colored hydroxide precipitates when mixed with aqueous sodium hydroxide solution. However zinc ions give a white hydroxide precipitate. These reactions can be used to help identify transition metal ions in solution.

Answer : The number placed in front of
should be, three (3).
Explanation :
Balanced chemical reaction : It is defined as the number of atoms of individual elements present on reactant side must be equal to the product side.
The given unbalanced chemical reaction is,

This chemical reaction is an unbalanced reaction because in this reaction, the number of atoms of chloride and sulfate ion are not balanced.
In order to balanced the chemical reaction, the coefficient 3 is put before the
, the coefficient 2 is put before the
and the coefficient 3 is put before the
.
Thus, the balanced chemical reaction will be,

Therefore, the number placed in front of
should be, three (3).
Answer: The percent ionization of
in a 0.050 M
solution is 8.9 %
Explanation:

cM 0 0

So dissociation constant will be:

Give c= concentration = 0.050 M and
= degree of ionisation = ?

Putting in the values we get:


percent ionisation =
A type of electromagnetic radiation would be electromagnetic waves
