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

For each reaction below, decide if the first stable organic product that forms in solution will create a new CC bond, and check
the appropriate box.
Next, for each reaction to which you answered "Yes" to in the table, draw this product in the drawing area below.
Note for advanced students: for this problem, don't worry if you think this product will continue to react under the current conditions
- just focus on the first stable product you expect to form in solution.

As the lead product manager at OrganometALEKS Industries, you are trying to decide if the following reaction will make a molecule
with a new C - C bond as its major product:
H₂N
O
H
1.
?
2. H3O+
If this reaction will work, draw the major organic product or products you would expect in the drawing area below. If there's more
than one major product, you can draw them in any arrangement you like. Be sure you use wedge and dash bonds if necessary, for
example to distinguish between major products with different stereochemistry.
0
If the major products of this reaction won't have a new CC bond, just check the box under the drawing area and leave it blank.
