Answer: A. unsaturated.
Explanation:
Unsaturated solution is defined as the solution in which more solute particles can be dissolved in the solvent.
Saturated solution is defined as the solution in which no more solute particles can be dissolved in the solvent.
Supersaturated solution is defined as the solution in which more amount of solute particles is present than the solvent particles.
Given: Solubility = 30g/100ml
If 100 ml can dissolve ionic compound = 30 g
300 ml can dissolve ionic compound =
Thus solubility is 90g/300 ml and dissolved salt is only 70 g , the solution is said to be unsaturated.
A redox reaction be used as a source of electrical energy only when two half-reactions are physically separated. <span>The electrons that are released at the anode flow through the wire, producing an electric current. Galvanic cells therefore transform chemical energy into electrical energy that can then be used to do work.</span>

(NH4),CO
(NH₄)₂ CO₃
Explanation:
The chemical formula for ammonium carbonate is (NH4),CO
Ammonium carbonate is made up of:
Ammonium ion
Carbonate ion
Ammonium ion is represented by NH₄⁺
Carbonate ion is represented by CO₃²⁻
Now to write the formula, we are going to use their combining powers;
NH₄⁺ CO₃²⁻
Combining
power 1 2
Exchange
of power 2 1
Formula of compound (NH₄)₂ CO₃
