(b) The mass of a single molybdenum atom is 1.59×10-22 g. Suppose enough Mo atoms were lined up like beads on a string to span a
1 answer:
Answer:N=1151724138 atoms
Explanation:The atomic radius of molybdenum atom is 145 picometers so lining up molybdenum atoms is like lining up the beads of radius 145 picometers
so one bead would cover the length of 145*2=290 picometers
hence the atom's diameter =D=290 picometers
D=290 *10^(-12)
also
Distance span= 33.4 cm
Distance span= 0.334m
As the Distance span adds up with no of atoms the resulting formula is
Distance span by atoms= No of atoms * atom's diameter

Answer:
See explanation below
Explanation:
This reaction is known as Ketone hydrolisis in acid medium. This involves the formation of an hemi cetal, and then, the acetal. This is often used to convert ketones or aldehydes in ethers.
The first step involves the reaction with the acid. The carbonile reacts with the acid and forms an alcohol there. The next step is the reaction of the alcohol, in this case, the methanol to form the hemi cetal. Then in the third step, we repeat the first step, using acid to turn the OH group into a great leaving group such water. Then the water leaves the molecule, leaving the space wide open in the next step for methanol, and the acetal is formed.
