Answer:
The correct option is: A) N₂
Explanation:
The Bond length of a chemical bond is the length of a chemical bond formed between two given atoms.
<u>Bond length is inversely proportional to the bond order</u> of the chemical bond, which is the total number of bonds between two atoms. <u>Thus as the bond order increases, the bond length decreases.</u>
A) N₂: The nitrogen-nitrogen bond in dinitrogen is a triple bond (N≡N).
Thus the bond order = 3.
B) O₂: The oxygen-oxygen bond in dioxygen is a triple bond (O=O).
Thus the bond order = 2.
C) SO₂: Sulfur dioxide is a resonance stabilized molecule and its resonance hybrid shows that the sulfur-oxygen bond in sulfur dioxide is a partial double bond.
Thus the bond order = 1.5
D) SO₃: Sulfur trioxide is a resonance stabilized molecule and its resonance hybrid shows that the sulfur-oxygen bond in sulfur trioxide is a partial double bond.
Thus the bond order = 1.33
<u>Since the bond order of N₂ is the largest, therefore, the N-N bond length is the shortest.</u>
Mass Spectrometer - is an analytical technique that ionizes chemical species and sorts the ions based on their mass-to-charge ratio. It measures the masses within a sample.
Answer:
True.
Explanation:
An example is:
HCl + NaOH ---> NaCl + H2O.
Answer:
Half-life = 1.21x10⁻⁴ years⁻¹
Explanation:
The kinetics decay of ¹⁴C follows the first order reaction. That means half-life of ¹⁴C is defined as:
Half-life = ln 2 / K
<em>Where K is decay constant.</em>
<em />
As decay constant of ¹⁴C is 5730 years, half-life is:
Half-life = ln 2 / 5730 years
<em>Half-life = 1.21x10⁻⁴ years⁻¹</em>
