Answer:

There is no structure, it depends on what the product contains

Explanation:

In considering a spectroscopic method of identifying a product, if the compound has hydrogen atom then the proton NMR is considered because it contains a nuclear spin.

on the other hand, if it contains carbon, whether Quaternary carbon, tertiary carbon or secondary carbon, then definitely carbon-13 NMR will be considered. and if the compound has a functional group and the group absorbs IR with a particular frequency, then IR will be used in characterizing the compound..

but if the compound when bombarded gives species of radical ion, then Mass spectroscopy will be used in identifying such compound

Arrange the following in order of increasing bond strength of the carbon oxygen bond:
Brilliant_brown [7]

Answer:

The correct option is: Carbonate ion < Carbon dioxide < Carbon monoxide

Explanation:

Bond energy is defined as the average energy needed to break a chemical covalent bond and signifies the strength of chemical covalent bond.

The bond strength of a covalent bond depends upon the <u>bond length and the bond order.</u>

Carbon monoxide molecule (CO) has two covalent bond and one dative bond. Bond order 2.6

Carbon dioxide (CO₂) has two carbon-oxygen (C-O) double bonds of equal length. Bond order 2.0

Carbonate ion (CO₃²⁻) has three C-O partial double bonds. Bond order 1.5

Also, the bond length is <u>inversely proportional to the bond order and bond strength.</u>

Therefore, <u>order of C-O bond length:</u> Carbon monoxide<Carbon dioxide<Carbonate ion

<u>Order of C-O bond order</u>: Carbonate ion<Carbon dioxide<Carbon monoxide

<u>Order of C-O bond strength or energy</u><u>: Carbonate ion<Carbon dioxide<Carbon monoxide</u>

1. Describe a procedure to separate a mixture of salt, sand, and water.
Brilliant_brown [7]
1.  A filter was used to separate the sand from the salt water solution (The process of decanting was used if a filer was not available).
2.  A Bunsen burner was used to boil away the water from the salt water solution leaving only salt.

I hope this helps.  Let me know if anything is unclear.
