Answer: -
Kinetic energy.
Explanation: -
Solids have the least kinetic energy and the highest intermolecular force of attraction among the three states of matter.
When heat energy is supplied to the solid, the kinetic energy of the solid particles increases. At some point, the kinetic energy becomes comparable to the intermolecular force of attraction. At that point solids change into liquids.
When further heat energy is given, at certain point the kinetic energy becomes far greater than the intermolecular forces of attraction. At that point it becomes gas.
Answer:
The elements of same group have similar chemical properties because they have same number of valence electrons.
Explanation:
Answer:
A. an acid
B. a base
C. conjugate base
D. conjugate acid
Explanation:
This question appears incomplete because it is starting with a "or".
However, the available question can still be answered.
An acid (according to "Bronsted-Lowry") is a chemical compound/specie that can donate hydrogen ion(s) in a reaction while a base is the compound/specie that can receive hydrogen ion(s). From this definition, <u>it can be deduced that</u> CH₃COOH <u>(ethanoic acid) is an acid (weak acid) because it can donate an hydrogen ion while</u> CH₃COO⁻ <u>is a base because it can receive a hydrogen ion</u>.
Also, a conjugate acid is the compound formed when an acid has donated a hydrogen ion to a base (i.e it is a base with hydrogen ion attached to it) while a conjugate base is the acid that has lost it's hydrogen ion. Thus, <u>the conjugate acid in the question is</u> CH₃OH <u>while the conjugate base in the question is</u> CH₃O⁻.
A. an acid
B. a base
C. conjugate base
D. conjugate acid
