When a metal and a nonmetal exchange electrons to make a cation and an anion, respectively, they can form an ionic compound. The
mario62 [17]

Answer:

Generally, we know that ionic compounds are formed by reaction of metals and non metals and non metals form a covalent  or non ionic bonds.

<u>IONIC COMPOUDS</u>

  • Iron and chlorine (FeCl2) , ( FeCl3)
  • Chlorine and Lithium (LiCl)
  • oxygen and calcium ( CaO)
  • Potassium and Sulphur ( K2S)

<u>NON IONIC COMPOUNDS</u>

  • Potassium and Calcium (covalent bond)
  • Sulphur and Bromine (covalent bond)

Write the net ionic equation for any precipitation reaction that may be predicted when aqueous solutions of calcium iodide and c
Hitman42 [59]

<u>Answer:</u> The net ionic equation is written below.

<u>Explanation:</u>

Net ionic equation of any reaction does not include any spectator ions.

Spectator ions are defined as the ions which does not get involved in a chemical equation. They are found on both the sides of the chemical reaction when it is present in ionic form.

The chemical equation for the reaction of calcium iodide and chromium (III) sulfate is given as:

3CaI_2(aq.)+Cr_2(SO_4)_3(aq.)\rightarrow 3CaSO_4(s)+2CrI_3(aq.)

Ionic form of the above equation follows:

3Ca^{2+}(aq.)+6I^{-}(aq.)+2Cr^{3+}(aq.)+3SO_4^{2-}(aq.)\rightarrow 3CaSO_4(s)+2Cr^{3+}(aq.)+6I^-(aq.)

As, chromium and iodide ions are present on both the sides of the reaction. Thus, it will not be present in the net ionic equation and are spectator ions.

The net ionic equation for the above reaction follows:

3Ca^{2+}(aq.)+3SO_4^{2-}(aq.)\rightarrow 3CaSO_4(s)

Hence, the net ionic equation is written above.
