To obtain number of atoms, multiply number of moles by the number of molecules per mole (Avogadro's number) and by the number of atoms per <u>molecule </u>(<u>in this case, there are six if you count them in CH3OH</u>). Therefore, 1.44 x 10^25 atoms in 128 grams of CH3OH.
I hope this helps and please mark brainlyest i need 5 to level up
Answer:
See explanation below
Explanation:
In this case we have the starting reactant which is the ethine, In the first step reacts with NaNH₂, a strong base. This base will substract the hydrogen from one of the carbon of the ethine, and form a carbanion. This will react with the propane bromide, displacing the bromine and forming a 5 carbon chain with the triple bond on the carbon 1 and 2.
In the second step, reacts with the lindlar catalyst to do a reduction, and form a double bond between carbon 1 and 2. In essence, compound A is similar to compound B.
Finally B reacts with water in acid and makes a addition reaction, and form an alcohol.
The whole process can be seen in the picture below.
Hope this helps
