QUESTION 1 2 points Answer True or False for the following statement: In the following chemical reaction, H is neither oxidized nor reduced. 4 Fe(OH)2 (s) + O2 (g) + 2H20 ( ) 2 Fe2O3-3H20 (s) O True O False QUESTION 2 2 points Answer True or False for the following statement: In the following chemical reaction, CaO is the reducing agent. 2Ca(s) + O2 (g) 2CaO (s) True O False QUESTION 3 2 points If you were to perform a similar procedure to Part II (Corrosion of Zinc), place the following solutions in order of increasing expected reactivity with zinc-plated nail (galvanized nail) (.e.which would react slowest with zinc as #1 leading up to which would react fastest as #4). (Hint: Use standard reduction potentials to help you) Ni(NO3)2 Br2 Fe(NO3)2 AgNO3

Explanation / Answer

1)

oxidation of H is +1 on both sides

So, H is neither oxidised nor reduced

Answer: True

2)

Ca is oxidised from 0 oxidation state to +2 oxidation state

O is reduced from 0 oxidation state to -2 oxidation state

So, Ca is reducing agent and O2 is oxidising agent

Answer: False
