O2 + ch4 co2 + h2o what would be the coefficient of the diatomic oxygen molecule in the balanced reaction?
2 answers:
Answer:
<h2>The coefficient of the diatomic oxygen has to be 2.</h2>Explanation:
The balanced reaction should be like this:
So, as you can see, balance mean that molecules in the reaction has to be equal, the amount of element involved has to be the same, due to the Conservation of the Mass Law.
So, Hydrogen and Oxygen are not balanced in the given expression, that's why we need to add those coefficients.

<u>Answer:</u> The standard electrode potential of the cell is 4.53 V.
<u>Explanation:</u>
We are given:
The substance having highest positive potential will always get reduced and will undergo reduction reaction. Here, fluorine will undergo reduction reaction will get reduced.
Aluminium will undergo oxidation reaction and will get oxidized.
Substance getting oxidized always act as anode and the one getting reduced always act as cathode.
To calculate the of the reaction, we use the equation:
Hence, the standard electrode potential of the cell is 4.53 V.
