. Balance each of the following oxidation-reduction reactions by inspection.

a. C 3 H 8 ( g ) + O ( g ) CO 2 ( g ) + H 2 O ( g )    b. CO ( g ) + H 2 ( g ) CH 3 OH ( l )    c. SnO 2 ( s ) + C ( s ) Sn ( s ) + CO ( g )    d. C 2 H 5 OH ( l ) + O 2 ( g ) CO 2 ( g ) +  H 2 O ( g )

Interpretation Introduction

(a)

Interpretation:

The given oxidation-reduction reaction should be balanced by inspection.

Concept Introduction:

The oxidation-reduction reaction is also known as a redox reaction. In this reaction, one reactant is oxidized and other is reduced. The balancing of oxidation-reduction reaction can be done by simple method by comparing the number of each atoms on both sides of the reaction arrow without addition of hydrogen ion, water molecule and electrons from outside.

Explanation

The given reaction is as follows:

C3H8g+O2gCO2g+H2Og

In the above reaction, to balance the carbon atom, give coefficient 3 to CO2 on right side of the reaction arrow.

C3H8g+O2g3CO2g+H2Og

Number of hydrogen atoms on left and right side of the reaction arrow is 8 and 2 respectively.

Give coefficient 4 to H2Og on right side of the reaction arrow to balance the number of hydrogen atoms
