Answer: Noble gases

Explanation: Noble gases constitutes the extreme right position in the periodic table,

They are have the smallest atomic radius and are the most unreactive elements present in the whole periodic table. There outermost shell of electrons that is valence shell of electrons is completely full thus there is no chance of loss or gain of electrons.

Thus noble gas elements are also known as Inert Gases.

Write the TOTAL IONIC EQUATION between zinc and hydrochloric acid.

Andreyy89

Answer : The net ionic equation will be,

$Zn(s)+2H^+(aq)\rightarrow Zn^{2+}(aq)+H_2(g)$

Explanation :

In the net ionic equations, we are not include the spectator ions in the equations.

Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.

The balanced ionic equation between zinc and hydrochloric acid will be,

$Zn(s)+2HCl(aq)\rightarrow ZnCl_2(aq)+H_2(g)$

The ionic equation in separated aqueous solution will be,

$Zn(s)+2H^+(aq)+2Cl^-(aq)\rightarrow Zn^{2+}(aq)+2Cl^-(aq)+H_2(g)$

In this equation, $Cl^-$ is the spectator ion.

By removing the spectator ion from the balanced ionic equation, we get the net ionic equation.

The net ionic equation will be,

$Zn(s)+2H^+(aq)\rightarrow Zn^{2+}(aq)+H_2(g)$
