Answer:
A supersaturated solution contains more dissolved solute than required for preparing a saturated solution and can be prepared by heating a saturated solution, adding more solute, and then cooling it gently. Excess dissolved solute crystallizes by seeding supersaturated solution with a few crystals of the solute.

Answer:
C. The lowest whole-number ratio of atoms in a molecule.
Explanation:
Hello there!
In this case, according to the definition of the empirical and the molecular equations, it is possible for us to consider the following example of molecular formula, C4H10, whose empirical formula is C2H5.
In such a way, it is possible for us to say that the empirical formula gives C. The lowest whole-number ratio of atoms in a molecule, as it is the result of the simplification of the molecular formula when possible.
Regards!
Explanation:
The given data is as follows.
Concentration of standard NaOH solution = 0.1922 M
Let the original acid solution concentration be x.
= 0.1 x M
= 10.00 mL (given)
The reaction equation is as follows.
Concentration × Volume of 
= Concentration × Volume of NaOH
x = 1.314 M
Therefore, we can conclude that the concentration of the original sulfuric acid solution is 1.314 M.
Answer:
since it is in grp 1, it will react with water like all other metals.
