Interpretation: The reason for fuel cells not being widely used although they generate electrical energy without any air pollution needs to be explained.

Explanation of Solution
A simple fuel cell involves the reaction of hydrogen and oxygen gas thus, the only product formed in the reaction is liquid water. The reason fuel cells to not widely used is that they required oxygen gas and hydrogen gas which are expensive to generate. Hydrogen gas is also difficult to store and currently, there are few filling stations available. Also, the cost of energy produced from the hydrogen fuel cell is more than any other energy source.

- Show the mechanism steps to obtain the lowerenergy intermediate: *see imagearrow_forwardSoap is made by the previous reaction *see image. The main difference between one soap and another soap isthe length (number of carbons) of the carboxylic acid. However, if a soap irritates your skin, they mostlikely used too much lye.Detergents have the same chemical structure as soaps except for the functional group. Detergentshave sulfate (R-SO4H) and phosphate (R-PO4H2) functional groups. Draw the above carboxylic acidcarbon chain but as the two variants of detergents. *see imagearrow_forwardWhat are the reactions or reagents used? *see imagearrow_forward
