Suppose a hydrogen-oxygen fuel-cell generator was used to produce electricity for a house. Use the balanced redox reactions and the standard cell potential to predict the volume of hydrogen gas (at STP) required each month to generate the electricity needed for a typical house. Assume the home uses 1600 of electricity per month.

Where do you want to go with this? You should start with the basic fuel cell equation. If you can't balance it show the reactants and explain what you don't understand about balancing redox equations.

To calculate the volume of hydrogen gas required each month to generate the electricity for a house using a hydrogen-oxygen fuel-cell generator, we need to follow these steps:

1. Determine the balanced redox reactions:
The conversion of hydrogen and oxygen to water in a fuel cell involves the oxidation of hydrogen (H₂) and the reduction of oxygen (O₂). The balanced redox reactions for this process are:
Anode (Oxidation): 2H₂(g) → 4H⁺(aq) + 4e⁻
Cathode (Reduction): O₂(g) + 4H⁺(aq) + 4e⁻ → 2H₂O(l)

2. Calculate the moles of electrons transferred:
For every mole of hydrogen gas (H₂) that is consumed, 4 moles of electrons are transferred. This is evident from the balanced redox reaction.

3. Calculate the number of moles of hydrogen gas required:
From the balanced redox reaction, we can infer that for every 2 moles of water produced, 1 mole of hydrogen gas is consumed. Therefore, for every mole of electrons transferred, 0.5 moles of hydrogen gas are required.

4. Determine the number of moles of electrons transferred in the consumption of electricity:
To determine this, we can use Faraday's Law of Electrolysis, which states that one Faraday of electricity (96,485 Coulombs) corresponds to the transfer of 1 mole of electrons.

The number of moles of electrons transferred can be calculated using the formula:
Moles of electrons = (Amount of electricity used in Coulombs) / (Faraday constant)

It is given that the house uses 1600 kWh (kilowatt-hours) of electricity per month. To convert this to Coulombs, we can use the relation:
1 kWh = 3.6 x 10^6 Coulombs

5. Calculate the volume of hydrogen gas required:
Finally, we can calculate the volume of hydrogen gas (at STP - standard temperature and pressure) required using the ideal gas law:
Volume of hydrogen gas = (Moles of hydrogen gas) x (Molar volume at STP)

The molar volume at STP is approximately 22.4 liters per mole.

By following these steps, we can determine the volume of hydrogen gas required each month to generate the electricity needed for a typical house.
