B) kinetic energy.
C) potential energy.
D) chemical energy.
Answer:
A) entropy
Explanation:
A) Pentanoid acid
B) Pentanal
C) Pentan-2-one
D) Propanoic acid and ethanoic acid
Answer:
C) Pentan-2-one
Explanation:
The product of the reaction of pentan-2-ol with acidified potassium dichromate is pentan-2-one.
Pentan-2-ol is a secondary alcohol, and secondary alcohols are oxidized to ketones by acidified potassium dichromate. The reaction is as follows:
CH3CH(OH)CH3 + K2Cr2O7 + H2SO4 → CH3COCH3 + Cr2(SO4)3 + K2SO4 + H2O
Propanoic and ethanoic acids are not products of this reaction.
Therefore, the answer is (C).

Answer: Covalent
Explanation:
A covalent bond is formed when an element shares its valence electron with another element. This bond is formed between two non metals. Example:
An ionic bond is formed when an element completely transfers its valence electron to another element. The element which donates the electron is known as electropositive element and the element which accepts the electrons is known as electronegative element. This bond is formed between a metal and an non-metal. Example:
Thus bond formed by sharing of electrons is covalent bond.
Astrophysics and planetar Astrophysics and planetary science are considered subspecialties of Astronomy. Astronomy is the study of the sun, moon, planets, stars, comets, gas, galaxies, dust and other bodies and phenomena.
Note
Astrophysics - properties of space
Planetary Science - planet formation
