Gnoma [55]

Answer:

The correct answer is option e.

Explanation:

The lead acid battery consists lead as an anode and lead oxide as a cathode. Both the electrodes are suspended in dilute sulfuric acid which act as an electrolyte.

At anode: Oxidation

Pb(s)+SO_4^{2-}(aq)\rightarrow PbSO_4(s)+2e^-

At cathode: Reduction

PbO_2+SO_4^{2-}(aq)+4H^+(aq)+2e^-\rightarrow PbSO_4(s)+2H_2O

Balance the following equation; then determine how many grams of CO2 will be produced when 40.0 mol of CO reacts with Fe2O3.
sashaice [31]

 Fe2O3      +       3CO -------->    2Fe    +      CO2

      1           :          3         :            2      :         3

   13.3       <---     40    ------> 26.6      --->     40    ( mol)

n = m/M

m CO2 = n.M = 13.3  .    40   =  532 ( g)

p/s : i hope that this will help  ( cause i'm not really good at english :}}} )
