Draw Lewis dot structure for both. Since H is an exception to the octet rule H2O doesnt require any double bonds. The answer in this question is 920 kj/mol CO2 has 2 double bonds answer is 1464 kj/mol.The bond dissociation energy needed to break all the bond in a mole of carbon dioxide co2 is 920 kj/mol.

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,

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