Answer : The balanced chemical reaction will be:

H_2O(l)\rightleftharpoons H^+(aq)+OH^-(aq)

Or,

H_2O(l)+H_2O(l)\rightleftharpoons H_3O^+(aq)+OH^-(aq)

Explanation :

Autoionization of water  : The autoionization of water means that the reaction water with water means self ionization.

In the autoionization of water, one water molecule loses an hydrogen ion and another one gains it.

The balanced chemical reaction will be:

H_2O(l)\rightleftharpoons H^+(aq)+OH^-(aq)

Or,

H_2O(l)+H_2O(l)\rightleftharpoons H_3O^+(aq)+OH^-(aq)

4.a) Draw two Lewis structures for HCP; one where C is central and one where P is central: b) Calculate formal charge for each a
love history [14]

One Hydrogen atom (H) and one Oxygen atom (O) surround the central Carbon atom (C) in the HCP Lewis structure (O). Carbon (C) and Phosphorus (P) have a triple bond, and Carbon (C) and Hydrogen (H) have a single bond.

<h3>How can you choose the ideal format for a formal charge?</h3>

The Lewis structure with the negative formal charges on the most electronegative atoms is the one to choose from when faced with a choice between numerous Lewis structures with similar formal charge distributions.

<h3>How do you determine the preferred resonance structure?</h3>

The resonance forms with the fewest non-zero formal charge atoms are selected. Resonance develops atoms that have a negative formal charge or are the most electronegative are preferred.

How many degrees of unsaturation are lost or gained in the base-induced transformation from mito-ph to its photoactive ring-open
Fudgin [204]

Unsaturation (IHD) 2 hydrogen Needed

IHD = [(2n+2) -H]/2
(H: X=1, N=-1, O= zero)

Unsaturation:
Double bonds = 1
Rings = 1
Triple Bonds = 2

The degrees of unsaturation in a molecule are additive — a molecule with one double bond has one degree of unsaturation, a molecule with two double bonds has two degrees of unsaturation, and so forth.

What is the oxidation number sulfur in H2S?
Nikolay [14]

The oxidation number sulfur in H₂S is -2.

A compound's total number of oxidations must be zero.

The two hydrogen atoms in the chemical hydrogen sulfide, H₂S, each have an oxidation number of +1, making a total of +2. As a result, the compound's sulfur has an oxidation number of -2, and the total number of oxidations is 0.

Assume that the sulfur atom in H₂S has an oxidation number of x.

S be x.

Now,

2+x=0

⇒x=−2

<h3>What is oxidation number?</h3>

The total number of electrons that an atom either receives or loses in order to create a chemical connection with another atom is known as the oxidation number, also known as the oxidation state.

Depending on whether we are taking into account the electronegativity of the atoms or not, these phrases can occasionally have a distinct meaning. Coordination chemistry commonly makes use of the phrase "oxidation number."

<h3>What distinguishes an oxidation number from an oxidation state?</h3>

In contrast to the oxidation state, which indicates how oxidised an atom is in a molecule, the oxidation number describes the charge that the core metal atom will retain once all ligands have been removed.

select the equations that are correctly balanced. h2o 2o2? h2o2 fe2o3 3h2? 2fe 3h2o al 3br2? albr3 caco3? cao co2 can you clarif
natta225 [31]
<span>The choices are as follows:
h2o + 2o2 = h2o2
 fe2o3 + 3h2 = 2fe + 3h2o
al + 3br2 = albr3
caco3 = </span><span>cao + co2

The correct answers would be the second and the last option. The equations that are correctly balanced are:

</span> fe2o3 + 3h2 = 2fe + 3h2o 
caco3 = cao + co2

To balance, it should be that the number of atoms of each element in the reactant and the product side is equal.
