<u>Answer:</u>
17%
<u>Explanation:</u>
Mass of a piece of copper calculated by student = 8.3 grams
Actual mass of copper = 10 grams
We know the formula for the percent error:
Percentage error = (| experimental value - actual value | / actual value) * 100
So substituting the given values in the above formula:
Percent error = (|8.3 - 10| / 10) * 100 = (1.7/10) * 100 = 17%
Answer:
2-methyl-2-pentanol is produced as a major product
Explanation:
- Double bond in 2-methyl-2-pentene is protonated first by consuming a proton from
. - A carbocation intermediate is formed after protonation of double bond. Most stable carbocation is formed as a major intermediate.
- Here a tertiary carbocation is formed as a major intermediate.
gives subsequent nucleophilic addition to the carbocation intermediate and produce 2-methyl-2-pentanol as a major product.- Reaction mechanism and major organic product has been shown below.

are polyatomic anions composed of two or more atoms.
<h3>What is a polyatomic anion?</h3>
A polyatomic ion is an ion composed of two or more atoms. Examples: The hydroxide cation (
) and the phosphate cation (
) are both polyatomic ions.
and
are the polyatomic anions because both contain more than 1 atom.
Hence,
and
are polyatomic anions composed of two or more atoms.
