How many equivalent lewis structures are necessary to describe the bonding in no2cl?
bogdanovich [222]

Answer:

The correct answer is "two".

Explanation:

The main bondings that has an effect in a Lewis structure in NO2Cl are the double bondings occurring between the Oxygen atoms and the Nitrogen atom. Since the NO2Cl compound has two oxygen atoms attached to the nitrogen atom, two equivalent lewis structures will be necessary to describe it. I attached an example of two equivalent Lewis structure corresponding to a NO2 molecule.

Compare the chemical a d structural formulas of butane and isobutane
defon
Butane and isobutane are structural isomers. Isobutane is produced by the isomerization reaction of butane.
CH3CH2CH2CH3--(t°,AlCl3)-›CH3CH(CH3)-CH3.
They have the same chemical formula C4H10.But structural formulas are different
Butane CH3CH2CH2CH3
Isobutane CH3CH(CH3)CH3
Isobutane has methyl radical.

For a particular collision, she detects the emitted products and find 15 protons, 2 antiprotons, 7 positrons, and 24 neutral par
Phantasy [73]

Explanation:

First of all , there were a total charge of +13e (6 protons from carbon and 7 protons from nitrogen), that  meant there requires to be a total charge of +13e after the collision occurred. Listed is 16 protons (+16e), 3 antiprotons (-3e), 8 positrons (+8e) and 16 neutral particles (0e), so the total charge listed is +21e, meaning an excess of +8e, meaning you need 8 electrons (-8e) to balance out the charge.

write chemical equation for the following decomposition reactions. Aluminum oxide(s) decomposes when electricity is passed throu
belka [17]

Answer:

2Al2O3 (l) ---> 4Al (l) + 3O2 (g)

Explanation:

The reaction is the electrolysis of aluminium oxide. It decomposes aluminium oxide (Al2O3) into aluminium metal (Al) and Oxygen (O2). In this process, aluminium oxide is molten (liquid state) so that ions can move to complete the electricity circuit.

Al2O3 (l) ---> Al (l) + O2 (g)

Balance the equation:

2Al2O3 (l) ---> 4Al (l) + 3O2 (g)
