Answer:
Approximately
.
Explanation:

The actual yield of
was given. The theoretical yield needs to be calculated from the quantity of the reactant.
Balance the equation for the hydrolysis of water:
.
Note the ratio between the coefficient of
and
:
.
This ratio will be useful for finding the theoretical yield of
.
Look up the relative atomic mass of hydrogen and oxygen on a modern periodic table.
Calculate the formula mass of
and
:
.
.
Calculate the number of moles of molecules in
of
:
.
Make use of the ratio
to find the theoretical yield of
(in terms of number of moles of molecules.)
.
Calculate the mass of that approximately
of
(theoretical yield.)
.
That would correspond to the theoretical yield of
(in term of the mass of the product.)
Given that the actual yield is
, calculate the percentage yield:
.
Answer:
A car stopped at the top of the hill
Explanation:
It's potenial energy because, the car could go down the hill and create kinetic energy. Hope this helps! Please give me brainly it is correct!
Answer:
Most substituted alkene is produced as a major product
Explanation:
- Dehydration of 3-methyl-2-butanol proceeds through E1 mechanism to form alkenes.
- Most substituted alkene is produced as major product because of presence of highest number of hyperconjugative hydrogen atoms corresponding to the produced double bond (Saytzeff product).
- Here, a H-shift also occurs in one of the intermediate step during dehydration to produce more stable tertiary carbocation.
- Reaction mechanism has been shown below.
