How many ions are in sucrose ? how many ions are in iron (iii) chloride?

            Zero Ions in Sucrose

            Four Ions in Iron (III) chloride

                  Ions are defined as those species which contain either positive charge or negative charge. On combination, these two different ions produces an Ionic compound. Hence, it can be concluded that ions are being produced by Ionic compounds when dissolved in suitable solvent (commonly water as polar solvent).

                   Sucrose fails to produce Ions in polar solvent because it is a covalent compound. It does not contain any ions.

                    While, Iron (III) chloride (FeCl₃) when dissolved in polar solvent ionizes as follow,

                                  FeCl₃ ₍s₎     →    Fe³⁺ ₍aq₎  +  3 Cl⁻ ₍aq₎

Therefore, it produces four ions i.e. one Fe³⁺ and three Cl⁻ ions respectively.

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.

c. electrical charges of ionic bonds.
