Following are the chemical and structural formulae of said complex compound,
More valence electrons and larger atomic radius are facts most suitable for increasing the electrical conductivity of metals.
They are two representatives of the sublevels/energy levels.
Answer:
< 0
Explanation:
Entropy is the measure of randomness or disorder of a system. If a system moves from an ordered arrangement to a disordered arrangement, the entropy is said to decrease and vice versa.
For the reaction
In this reaction gaseous reactants are converting to solid products. The randomness will decrease and hence entropy will also decrease. Thus
is negative or less than zero.
Answer:
- <em>Brønsted-Lowry acid: HNO₂</em>
- <em>Brønsted-Lowry base: NH₃</em>
- <em>Conjugate acid: NH₄⁺</em>
- <em>Conjugate base: NO₂⁻</em>
Explanation:
The equation is:

<em>Brønsted-Lowry acids</em> are H⁺ donors.
<em>Brønsted-Lowry bases</em> are H⁺ acceptors.
Thus, on the left side, <em>HNO₂</em> is the acid and <em>NH₃ </em>is the base.
The <em>conjugate acids</em> and <em>conjugate bases</em> are on the right side of the equation.
The <em>conjugate acid</em> is the spieces that is formed after a base accepts the proton; thus it is <em>NH₄⁺</em>. A <em>conjugate acid</em> contains one more H atom and one more + charge than the base that formed it.
The <em>conjugate base</em> is the species that is formed after the acid donates its proton; thus, <em>NO₂⁻</em> is the <em>conjugate base</em>. A <em>conjugate base</em> contains one less H atom and one more - charge than the acid that formed it.
Summarizing:
- Brønsted-Lowry acid: HNO₂
