<u>Answer:</u> There is no predicate adjective in the sentence.
<u>Explanation:</u>
Predicate adjective is defined as an adjective that follows the linking verb and modifies the subject of the linking verb.
For Example:
The shoes look expensive.
In this sentence, the shoes are the subject, 'look' is the linking verb and 'expensive' is the predicate adjective.
The predicate adjective modified the subject.
In the given sentence,
'Five' is a common noun, 'cookies' is the subject, 'are' is the helping verb, 'on' is the preposition, 'the' is an article and 'table' is a countable noun.
Hence, there is no linking verb and therefore, this sentence has no predicate adjective.
Answer:
S²⁻(aq) + Cr²⁺(aq) ⇄ CrS(s)
Explanation:
The molecular equation includes all the species in the molecular form. Usually, it is useful to write this first to balance the equation. This is a double displacement reaction.
K₂S(aq) + Cr(NO₃)₂(aq) ⇄ 2 KNO₃(aq) + CrS(s)
The full ionic equation includes all ions and the species that no dot dissociate in water.
2 K⁺(aq) + S²⁻(aq) + Cr²⁺(aq) + 2 NO₃⁻(aq) ⇄ 2 K⁺(aq) + 2 NO₃⁻(aq) + CrS(s)
The net ionic equation includes only those ions that participate in the reaction and the species that do not dissociate in water.
S²⁻(aq) + Cr²⁺(aq) ⇄ CrS(s)
I think the answer is Joule.
As an amount of energy (being transferred), the SI unit of heat is the joule (J).
Answer:
Explanation:
Hello,
In this case, for the given reaction, the equilibrium constant turns out:
![Keq=\frac{[B]}{[A]}=\frac{0.5M}{1.5M} =1/3](https://tex.z-dn.net/?f=Keq%3D%5Cfrac%7B%5BB%5D%7D%7B%5BA%5D%7D%3D%5Cfrac%7B0.5M%7D%7B1.5M%7D%20%3D1%2F3)
Nonetheless, we are asked for the reverse equilibrium constant that is:
Which is greater than one.
In such a way, the Gibbs free energy turns out:
Now, since the reverse equilibrium constant is greater than zero its natural logarithm is positive, therefore with the initial minus, the Gibbs free energy is less than zero, that is, negative.
