Batteries being galvanic cells and the use of hydrogen-oxygen by the U.S. space program to produce power for its spacecraft are given. The concept behind the working of fuel cells and battery is to be stated. Concept introduction: Batteries are a combination of galvanic cells. Just like galvanic cell, the value of cell potential decreases as the battery discharges and attains the zero value at equilibrium. Fuel cells are also used for the generation of electricity. The hydrogen-oxygen fuel cells are used for the power generation in the spacecraft and they are eco-friendly. To determine: The effect of discharge of battery over E cell ; effect of equilibrium over the system and; similarities and differences between battery and fuel cells; the concept of hydrogen-oxygen fuel cell

Can you please color-code and explain how to solve this and any molecular orbital diagram given? I'm so confused; could you provide baby steps regardless of which problem type they gave me?
Consider the following structure.
OH
Esmolol
The synthesis of this compound uses a building block derived from either ethylene oxide or epichlorohydrin.
1) Determine which building block was used: |
2) Draw the structure of the nucleophiles that were used along with this building block in the synthesis of the molecule.
• Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner.
You do not have to consider stereochemistry.
