Balance the following reactions using either the oxidation number method or the half-reaction method. Identify which element has

$6Ce^{4+} + I^- + 6OH^-$ → $6Ce^{3+} + IO_3^- + 3H_2O$ is the balanced chemical equation.

<h3>What is a balanced chemical equation?</h3>

A balanced chemical reaction is an equation that has equal numbers of each type of atom on both sides of the arrow.

Half-reaction method:

Unbalanced chemical equation:

$Ce^{4+} + I^-$ → $Ce^{3+} + IO^{3-}$

Oxidation half-reaction:

$I^-+ 6OH^- - 6e-$ → I $O^{3-} + 3H_2O$

Reduction half-reaction:

$Ce4^+ + e^-$ → $Ce^{3+}$

Balanced chemical equation:

$6Ce^{4+} + I^- + 6OH^-$ → $6Ce^{3+} + IO^{3-} + 3H_2O$

Oxidation number method:

Unbalanced chemical equation:

$Ce^{4+} + I^-$ → $Ce^{3+} + IO^{3-}$

$I^{-1} -6e^-$ → $I^{+5}$

$Ce^{4+} + e^-$ → $Ce^{3+}$

Balanced chemical equation:

$6Ce^{4+} + I^{-1}$ → $6Ce^{3+} + I^{+5}$

$6Ce^{4+} + I^- + 6OH^-$ → $6Ce^{3+} + IO_3^- + 3H_2O$

Hence, $6Ce^{4+} + I^- + 6OH^-$ → $6Ce^{3+} + IO_3^- + 3H_2O$ is the balanced chemical equation.

Write an equation to show how hco3− can act as a base with hs− acting as an acid.

Ne4ueva [31]

Answer: $HCO_{3}^{-}+ HS^{-}\rightleftharpoons H_{2}CO_{3} + S^2{-}$

Explanation:

According to Bronsted and Lowry an acid is a proton donor and base is a proton acceptor.

Therefore, the equation for the reaction will be as follows.

$HCO_{3}^{-}+ HS^{-}\rightleftharpoons H_{2}CO_{3} + S^2{-}$

Here, $HCO_{3}^{-}$ acts as a base as it is accepting a proton and $HS^{-}$ acts as an acid because it is donating a proton.
