Write the NET IONIC EQUATION between zinc and hydrochloric acid.
makkiz [27]

Answer:

Zn_{(s)}+2H^{+}_{(aq)}\rightarrow Zn^{2+}_{(aq)}+H_2_{(g)}

Explanation:

Zinc reacts with hydrochloric acid to given zinc chloride and hydrogen gas. The liberation of the hydrogen gas can be confirmed by burning the gas. If the gas burns with pop sound, it means it is hydrogen gas

The molecular chemical equation for the reaction is:

Zn_{(s)}+2HCl_{(aq)}\rightarrow ZnCl_2_{(aq)}+H_2_{(g)}

The total ionic equation is:

Zn_{(s)}+2H^{+}_{(aq)}+2Cl^{-}_{(aq)}\rightarrow Zn^{2+}_{(aq)}+2Cl^{-}_{(aq)}+H_2_{(g)}

The net ionic equation is:

Zn_{(s)}+2H^{+}_{(aq)}\rightarrow Zn^{2+}_{(aq)}+H_2_{(g)}

Given that Cu + 2HCI Cu2+ + 2CI- + H2(g) has an overall reduction potential of –0.34 V, what is a valid prediction about how thi
dimaraw [331]

  Cu + 2HCI → Cu²⁺ + 2CI⁻ + H2(g)

has an overall reduction potential of –0.34 V      

The correct option is:

The reaction is not spontaneous and will require energy to proceed.

Since  the overall reduction potential is negative,the reaction is not spontaneous and it requires energy to proceed.
