Answer:
Total 5 significant digits.
Explanation:
Significant digits are the numbers that give a meaningful contribution. For example, digit 013 has the 2 significant digits and zero is not a significant digit because digits 1 and 3 give meaningful contribution but digit zero does not value meaningful contribution. Similarly, the 89015 has a total of 5 significant digits and these digits are the 8, 9, 0, 1, and 5.
Answer: The number of protons plus the number of neutrons equals the atomic mass.

Explanation:
The acid-catalyzed hydration of 1-methylcyclohexene proceeds by an SN1 mechanism. The reaction involves the formation of carbocations.
Two carbocations are formed leading to the major and minor products. The major product is obtained from the tertiary (more stable) carbocation while the minor product is obtained from the secondary (less stable carbocation).
Tertiary alcohols are not oxidized, hence the major product does not undergo oxidation. However, secondary alcohols are oxidized to ketones.
What occures is that the solution is know considered to be alkali, OH- ions react with the H+ ions from acids.
hope that helps :)
