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
The answer is
Cs + Br2 ⇌

Since the sign is positive, the entropy increased by 88.48 J/K.
Examine the phases of the species present to determine whether a physical or chemical process will cause an increase or decrease in entropy. Keep in mind "Silly Little Goats" to aid you in telling.
[1 Sf K+1 + 1 Sf Br-1 (aq)] ([1Sf(KBr (s))])
[1(102.5) + 1(82.42)] - [1(96.44)] = 88.48 J/K
If the entropy has grown, we say that Delta S is positive, and if it has dropped, we say that Delta S is negative. Due to its ionic nature, KBr is soluble in water and causes the 'K(+)' ions to hydrate.
