In resonance structures, the chemical connectivity in the molecule is same but the distribution of electrons are different around the structure. They are created by moving electrons in double or triple bonds, and not atoms.
Phenol,
and methanol,
both are alcohols that contain an
group attached to carbon atom.
Due to loss of 1
from phenol, it forms phenoxide anion and due to presence of double bond in the benzene ring the negative charge on the oxygen atom (which represents electrons) will resonate with double bonds of benzene ring as shown in the image. The resonance-stabilized phenoxide ion is more stable. Whereas when methanol lose 1
it forms methoxide anion and there are no such electrons present in the structure of methoxide that will result in the movement of electron. Since, due to resonance-stabilized phenoxide ion is more stable than methoxide ion, so it is a stronger acid.
The structures of the anions resulting from loss of 1
from phenol and methanol is shown in the image.
Answer:
Properties of Metals:
- Shiny
-Malleable
-Good Conductors of electric current
- Good conductors of heat
Properties of Non-metals:
- Dull
- Not Malleable
- Bad conductors of electric current but good electric insulators
- Poor conductors of heat
Note: The first dash for the Properties of metals goes with the first dash of Properties of Non-metals and so on.
24.25 moles of NO can be produced using 97 moles of HNO3.
<h3>What is balanced chemical equation?</h3>
Equal numbers of atoms from various elements are present in both the reactants and the products in balanced chemical equations. Varied elements' atom counts in the reactants and products of unbalanced chemical equations are different.
3 Cu + 8HNO3 g → 3 Cu(NO3)2 + 2 NO + 4 H2O
The number of moles consumed can be calculated using comparing with coefficients in the balanced reaction .
So , from above eq we get that 8 moles of HNO3 are consumed to make 2 moles of NO.
⇒ 8 HNO3⇔2 NO
⇒ 1 HNO3⇔ 1/4 NO
This means that for each mole of HNO3 produces 1/4 moles of NO.
So , for 97 moles of HNO3 ,
moles of NO can be made,
So, total moles of NO made are 24.25 moles.

The balanced equation for the dissolving of aluminum chloride into an aqueous solution with the dissociation of the ions is; AlCl3(s) → Al^3+ (aq) + 3 Cl^-(aq).
<h3>What is an equation?</h3>
An equation is a representation of the change that occurs inside a reaction vessel. Usually, we use this tool to show on paper, a process that we can not see with or eyes.
