Answer: A lot of food chains
Explanation: A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community.
C6h12o6 is the chemical formila for monosaccarides
Answer:
the weight of the atmosphere pressing down on Earth
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>
