Answer : The number of moles of is, 0.1 moles
Solution : Given,
Mass of = 6.2 g
Molar mass of = 62 g/mole
Now we have to calculate the moles of .
Therefore, the number of moles of present in 6.2 g is, 0.1 moles

After reading a book about parrots, Tani wants to learn more about them. The question that could be answered through scientific investigation is letter B, ‘What substances make up an eggshell?’ The other choices cannot be answered through scientific investigation.
Answer:
B
Explanation:
the form of compound
There are several methods that can be used for the reduction of 9-fluorenone. One of the most common methods is the use of sodium borohydride (NaBH4) as a reducing agent.
The reaction mechanism for this method is as follows:
Step 1: The NaBH4 molecule donates a hydride ion (H-) to the carbonyl group of 9-fluorenone, forming an alkoxide intermediate.
Step 2: The alkoxide intermediate is then protonated by a proton source (such as water or an acid) to form the corresponding alcohol.
The overall reaction can be represented as:
9-fluorenone + NaBH4 + H2O → 9-fluorenol + Na+ + BH3OH-
Another method that can be used for the reduction of 9-fluorenone is the use of lithium aluminum hydride (LiAlH4) as a reducing agent. The reaction mechanism for this method is similar to that of the NaBH4 reduction, with the LiAlH4 molecule donating a hydride ion to the carbonyl group of 9-fluorenone and the resulting alkoxide intermediate being protonated to form the corresponding alcohol. The overall reaction can be represented as:
9-fluorenone + LiAlH4 + H2O → 9-fluorenol + Li+ + AlH3OH-
Both of these methods are effective for the reduction of 9-fluorenone, and the choice of which method to use will depend on the specific conditions and requirements of the reaction.
