Answer:B
Explanation: A chemical change is something that is irreversible
Answer:
The correct answer is c) Electronegativity
Explanation:
The Z corresponds to the atomic number (defines the number of protons in the nucleus and also the electrons present in the atom). The Z increases from left to right in the same period, this is due to less shielding of the electrons in the last layer. Electronegativity (defined as the ability of the atoms to attract, in a covalent chemical bond, the electrons that it shares with other atoms), increases, the greater the Z (there is less distance).
Answer is: C. CH3CHOHCH3.
Balanced chemical reaction of hydration of propene:
CH₃CH=CH₂ + H₂O → CH₃CHOHCH₃.
A hydroxyl group (OH⁻) attaches to one carbon of the double bond and a proton (H⁺) adds to the other carbon of the double bond according to Markovnikov's rule (hydrogen gets attached to the carbon with more hydrogen substituents).
Product of this reaction is propan-2-ol (isopropyl alcohol).
