follow all the steps - 1- Step: Write the two half-reactions that contain the elements being oxidized and reduced. Use entire molecule or ion.Add the two half- reactions together, cancelling electrons and any other identical substances (like H2O and H+) that appear on opposite sides of the equation.2- Step: Check if the charge is balanced on both sides of the equation. Below is an example you should follow on how to check if the equation is balanced on both sides 2- Step : Check if the charge and elements are balanced:                                                                                                                                         16× (+1) = +16               2× (+2) = +4

2× (-1)   = -2                   5× (0)  = 0

5× (-2)   = -10 +              8× (0) = 0 +

                 +4                               +4

Q1. The following reaction is balanced. Show ALL steps that were involved in balancing this equation:

Zn + Hg2+ → Zn2+ + Hg Step - complete the following, assign oxidation number to each element to identify the element being oxidised and reduced.

Reactant Ox # Product Ox #

Zn

 

Hg2+

2- Step: Write the two half-reactions that contain the elements being oxidized and reduced. Use entire molecule or ion. Add the two half- reactions together, cancelling electrons and any other identical substances (like H2O and H+) that appear on opposite sides of the equation.3- Step: Check if the charge is balanced on both sides of the equation.Complete the sentences from the reading above with your answers from Q1.Choose from the following: reduced, oxidised, reducing agent, oxidising agent.Q2. The zinc atom (Zn) is 4__oxidized_______ to Zn2+ and ats as a(n) ________. Hg2+ is ____________ to Hg and acts as a(n) ___________.

Q3. The following reaction is unbalanced. Balance the lithium- iodide battery redox reaction described in reading. Show ALL steps to balance this equation:
