Respuesta :
1) C3H6(OH)2 : this compound must be propan-1,2-diol or propylene glycol
This is covalent compound and will not dissociate in water so the chemical speceis present will be
H2O and C3H6(OH)2
2) FeI3: this is ionic compound and will dissociate to form
FeI3 ---> Fe+3 + 3I-
chemical species present : H2O , Fe^+3 and I^-1
3) C3H8O : this must be propanol again it will remain undissociated
so the chemical species present will be HeO and C3H6(OH)2
(1) The chemical species present will be [tex]\boxed{{{\text{H}}_{\text{2}}}{\text{O}}}[/tex] and [tex]\boxed{{{\text{C}}_{\text{3}}}{{\text{H}}_{\text{6}}}{{\left( {{\text{OH}}} \right)}_{\text{2}}}}[/tex].
(2) The chemical species present will be [tex]\boxed{{\text{F}}{{\text{e}}^{{\text{3}} + }}}[/tex], [tex]\boxed{{\text{3}}{{\text{I}}^ - }}[/tex] and [tex]\boxed{{{\text{H}}_{\text{2}}}{\text{O}}}[/tex].
(3) The chemical species present will be [tex]\boxed{{{\text{H}}_{\text{2}}}{\text{O}}}[/tex] and [tex]\boxed{{{\text{C}}_{\text{3}}}{{\text{H}}_{\text{8}}}{\text{O}}}[/tex]. For table (refer to the image attached).
Further Explanation:
Covalent compounds are those compounds which are formed by the electron sharing between two or more non-metals. Covalent bonds involve two atoms that share electrons and reach a more stable electron configuration
Ionic compounds are those compounds formed from the ions of the species. Ions are the species that are formed due to the loss or gain of electrons. Cation forms by the loss of electrons and anion forms by the gain of electrons in a neutral atom. The ionic bond is a chemical bond between two atoms in which one atom donates its electron to another atom.
Compounds made from two elements can either have an ionic or covalent bond.
(i) If a bond is formed from a metal and a non-metal then it will be ionic.
(ii)If a bond is formed from two non-metals then it will be covalent.
Ionic reaction:
The ionic reaction is a chemical reaction in which molecules dissociate into ions in water. In ionic reaction, net charge is same on both sides.
(1) [tex]{{\mathbf{C}}_{\mathbf{3}}}{{\mathbf{H}}_{\mathbf{6}}}{\left( {{\mathbf{OH}}} \right)_{\mathbf{2}}}[/tex]
In [tex]{{\text{C}}_{\text{3}}}{{\text{H}}_{\text{6}}}{\left( {{\text{OH}}} \right)_{\text{2}}}[/tex], carbon (C), oxygen(O) and hydrogen(H) are nonmetals and form covalent bonds. Therefore, [tex]{{\text{C}}_{\text{3}}}{{\text{H}}_{\text{6}}}{\left( {{\text{OH}}} \right)_{\text{2}}}[/tex] is a covalent compound and will not dissociate in water. The chemical species present will be [tex]{{\text{H}}_{\text{2}}}{\text{O}}[/tex] and [tex]{{\text{C}}_{\text{3}}}{{\text{H}}_{\text{6}}}{\left( {{\text{OH}}} \right)_{\text{2}}}[/tex].
(2) [tex]{\mathbf{Fe}}{{\mathbf{I}}_{\mathbf{3}}}[/tex]
In [tex]{\text{Fe}}{{\text{I}}_{\text{3}}}[/tex], Iron (Fe) is metal and iodine (I) is a nonmetal and they will form an ionic compound. Therefore, [tex]{\text{Fe}}{{\text{I}}_{\text{3}}}[/tex] is an ionic compound and will dissociate into ions in water.
The dissociation reaction of [tex]{\text{Fe}}{{\text{I}}_{\text{3}}}[/tex] into ions is as follows:
[tex]{\text{Fe}}{{\text{I}}_{\text{3}}} \to {\text{F}}{{\text{e}}^{{\text{3}} + }} + {\text{3}}{{\text{I}}^ - }[/tex]
Hence, the chemical species present will be [tex]{\text{F}}{{\text{e}}^{{\text{3}} + }}[/tex], [tex]{\text{3}}{{\text{I}}^ - }[/tex] and [tex]{{\text{H}}_{\text{2}}}{\text{O}}[/tex].
(3) [tex]{{\text{C}}_{\text{3}}}{{\text{H}}_{\text{8}}}{\text{O}}[/tex]
In [tex]{{\text{C}}_{\text{3}}}{{\text{H}}_{\text{8}}}{\text{O}}[/tex] carbon (C), oxygen (O) and hydrogen (H) are nonmetals and form covalent compound. Therefore, [tex]{{\text{C}}_{\text{3}}}{{\text{H}}_{\text{8}}}{\text{O}}[/tex] is a covalent compound and will not dissociate in water. The chemical species present will be [tex]{{\text{H}}_{\text{2}}}{\text{O}}[/tex] and [tex]{{\text{C}}_{\text{3}}}{{\text{H}}_{\text{8}}}{\text{O}}[/tex].
