The correct answer is A) Concentration. See the explanation below, please.
Explanation:
We refer to concentration on the ratio between solute and solvent of a chemical solution. In the case of a more dilute solution, there is a higher proportion of solvent than solute and the opposite occurs in a concentrate.
NH₄NO₃ - ammonium-nitrate.
(NH₄)₂CO₃ - ammonium carbonate.
NH₄CN - ammonium cyanide.
(NH₄)₃PO₄- ammonium phosphate.
Sn(NO₃)₄ - tin(IV) nitrate.
Sn(CO₃)₂ - tin(IV) carbonate.
Sn(CN)₄ - tin(IV) cyanide.
Sn₃(PO₄)₄ - tin(IV) phosphate.
Fe(NO₃)₃ - iron(III) nitrate.
Fe₂(CO₃)₃ - iron(III) carbonate.
Fe(CN)₃ - iron(III) cyanide.
FePO₄ - iron(III) phosphate.
Mg(NO₃)₂ - magnesium nitrate.
MgCO₃ - magnesium carbonate.
Mg(CN)₂ - magnesium cyanide.
Mg₃(PO₄)₂ - magnesium phosphate.
