Consider the resonance structures for the carbonate ion. carbonate is a carbon double bonded to an oxygen with two lone pairs an
Bumek [7]

Answer:

The correct answers are: <u>Each oxygen of carbonate ion has -2/3 or -0.67 charge.</u>

<u>Bond order of each carbon‑oxygen bond in the carbonate ion</u> = <u>1.33</u>

Explanation:

The carbonate ion (CO₃²⁻) is an organic compound, in which a carbon atom is covalently bonded to three oxygen atoms. The net formal charge on a carbonate ion is −2.

The carbonate ion is <u>resonance stabilized</u> and has three equivalent resonating structures, which exhibits that all the three carbon-oxygen bonds in a carbonate ion are equivalent.

In the resonance hybrid of carbonate ion,<u> the negative charge is equally delocalized on all the three oxygen atoms. </u>

<u>Thus, each bonded oxygen has -2/3 or -0.67 charge.</u>

<u />

In a carbonate ion there is one double bond oxygen (C=O) and two single bonded oxygen (C-O). Bond order of 1 C=O is 2 and bond order of C-O is 1.

∴ <u>Bond order</u> = sum of all bond orders ÷ number of bonding groups = (2+1+1) ÷ 3 = <u>1.33</u>

Ber [7]

Answer:

Chemoautotrophs

Explanation:

Autotrophs are groups of organisms that are capable of manufacturing their own food (organic molecules) through the fixation of carbon dioxide. There are two types of autotrophs:

  • <em>Photoautotrophs fix carbon dioxide by using light as the energy for driving the process.</em>
  • <em> </em><em>Chemoautotrophs f</em><em>ix carbon dioxide by  using energy from the oxidation of inorganic molecules such as magnesium, or sulfur.</em>

Chemoautotrophs usually inhabit extreme environment such hot vents, deep sea, etc.

Ksju [112]

Answer:

Intensity

Explanation:

The correct answer is -Intensity

Reason -

Intensity has no affect on whether or not the photoelectric effect occurs.

As frequency , wavelength are inversely proportional.
