Any compound that increases the number of hydronium ions when dissolved in water is called an acid.
The reality is that anything that raises the concentration of hydronium ions in a solution or causes the production of hydronium ions during its dissociation qualifies as an acid.
As a result, a substance can only dissociate, produce hydronium ions, and be classified as an acid when it is in aqueous solution.
The hydronium ion can form when an acid is present in water, even just in pure water. Its chemical name is H3O+. It can also be produced by the interaction of an H+ ion and an H2O molecule.
The trigonal pyramidal geometry of the hydronium ion is composed of three hydrogen atoms and one oxygen atom.
A proton from the Arrhenius acid molecules, also referred to as a positive hydrogen ion (H+), is transferred to the surrounding water molecules as the Arrhenius acid dissolves in the liquid.

WILL MARK BRAINLIEST PLS SAVE ME FROM THAT ANN OYING GUY
You can identify the limiting reactant and the surplus reactant in a chemical reaction if you know how many moles are needed for one of the reactants.
To do this, compare the number of moles of the necessary reactant to that of the accessible reactant. The limiting reactant is the one that results in the smallest quantity of product, and the excess reactant is the one that results in the most significant amount of product.
StepsConsider a reaction where 4 moles of the product are produced from 2 moles of reactant A and 3 moles of reactant B. The following calculation can be used to identify the limiting reactant if you have 4 moles of reactant A and 6 molecules of reactant B:
4 moles of reactant A / 2 moles required of reactant A equals 2.
6 moles of reactant B divided by 3 molecules of reactant B needed equals 2.
There is no surplus because both reactants yield the same amount of product, meaning they are both fully utilized. One reactant would be limiting and the other would be in excess of the computations that had yielded a different result.

12a. sigma complexes are the intermediates for electrophilic aromatic substitution (eas). what are the intermediate complexes for nucleophilic aromatic substitution (snar) called
Sigma complexes are the intermediates for electrophilic aromatic substitution (eas). The intermediate complexes for nucleophilic aromatic substitution (SNAR) are called: pi complexes.
Pi complexes form when a nucleophile, or electron-rich species, attacks an electron-deficient atom in an aromatic ring. This attack displaces the electron-deficient atom, and a pi bond is formed between the nucleophile and the aromatic ring. The displacement of the electron-deficient atom results in the formation of an intermediate pi complex.
The pi complex is a key intermediate in SNAR reactions. The pi complex can then be attacked by another nucleophile, resulting in the formation of a new aromatic compound. During this reaction, the aromaticity of the ring is maintained and the stability of the pi complex is increased.
The pi complex is a key intermediate in the EAS mechanism. In order for the reaction to take place, the pi complex must be stable. This means that the electrons must be properly distributed around the ring and the nucleophile must be strongly bound to the electron-deficient atom.
This stability helps to ensure that the reaction will proceed efficiently and that the desired product is formed. In conclusion, the intermediate complexes for nucleophilic aromatic substitution (SNAR) are called pi complexes. Pi complexes form when a nucleophile attacks an electron-deficient atom in an aromatic ring.
The displacement of the electron-deficient atom results in the formation of an intermediate pi complex, which is then attacked by another nucleophile, resulting in the formation of a new aromatic compound. The stability of the pi complex is essential for the successful completion of the reaction.

Arrange these species by their ability to act as an oxidizing agent. Best oxidizing agent Au3+ Fe2+ 2+ Na+ Poorest oxidizing agent Answer Bank
AlthoughNa⁺ and Fe²⁺ are typically weaker oxidising agents than Au³⁺ , this may not always be the case in every process.
An oxidizing agent is a species that causes oxidation by accepting electrons or donating oxygen, and therefore it is characterized by having a high oxidation state. In general, the ability to act as an oxidizing agent increases as the oxidation state of the species increases. Based on this, we can arrange the given species in order from best to poorest oxidizing agent as follows:
Au³⁺ > Fe²⁺ > Na⁺
Among these species, Au³⁺ has the highest oxidation state and therefore the strongest ability to act as an oxidizing agent. Fe²⁺ has a lower oxidation state than Au³⁺, but it is still capable of acting as an oxidizing agent in certain reactions. Na⁺ has the lowest oxidation state of the three and is therefore the poorest oxidizing agent among them.
It's important to note that the ability to act as an oxidizing agent also depends on other factors, such as the nature of the other reactants involved and the reaction conditions.
Therefore, while Au³⁺ is generally a stronger oxidizing agent than Fe²⁺ and Na⁺, this may not always be the case in every reaction.

With a pressure rise to 11.1 atm, the hydrogen gas volume is 2.03 L.
To solve this problem, we can use the combined gas law, which relates the pressure, volume, and temperature of a gas. The equation for the combined gas law is:
P₁V₁/T₁ = P₂V₂/T₂
Where P₁, V₁, and T₁ are the initial pressure, volume, and temperature, respectively, and P₂, V₂, and T₂ are the final pressure, volume, and temperature, respectively.
We can rearrange this equation to solve for V₂:
V₂ = (P₁V₁T₂)/(P₂T₁)
We are given that the initial volume (V₁) is 4.4 L, the initial pressure (P₁) is 4.9 atm, and the final pressure (P₂) is 11.1 atm. We are asked to find the final volume (V₂) when the pressure is increased to 11.1 atm.
We can assume that the temperature (T₁) is constant, since it is not specified otherwise. Therefore, we can substitute the values into the equation and solve for V₂:
V₂ = (P₁V₁T₂)/(P₂T₁)
V₂ = (4.9 atm)(4.4 L)(273 K)/(11.1 atm)(273 K)
V₂ = 2.03 L
Therefore, the volume of the hydrogen gas is 2.03 L when the pressure is increased to 11.1 atm.

predict the major organic product formed on thermal decarboxylation of the following compound.
The compound given is 3-methyl-2-pentenoic acid.
Thermal decarboxylation of 3-methyl-2-pentenoic acid is a reaction in which the carboxylic acid group is removed from the molecule, resulting in the formation of an alkene.
In this reaction, the acid group is first protonated and then the bond between the alpha carbon and the carboxyl oxygen is broken. The major organic product formed on thermal decarboxylation of 3-methyl-2-pentenoic acid is 2-methyl-1-pentene.
The initial step of the reaction involves the protonation of the carboxylic acid group of 3-methyl-2-pentenoic acid by a strong acid, typically sulfuric acid. This protonation activates the carboxyl group and makes it more susceptible to decarboxylation.
The subsequent step involves the breaking of the bond between the alpha carbon and the carboxyl oxygen, resulting in the loss of carbon dioxide and the formation of the alkene. The formed alkene in this reaction is 2-methyl-1-pentene.
Therefore, the major organic product formed on thermal decarboxylation of 3-methyl-2-pentenoic acid is 2-methyl-1-pentene.

The number of moles of MgCO₃ is also 0.200 moles and the mass of magnesium carbonate at the start was 16.86 g.
The balanced chemical equation for the reaction between sulfuric acid (H₂SO₄) and magnesium carbonate (MgCO₃) is:
H₂SO₄ + MgCO₃ → MgSO₄ + CO₂ + H₂O
From the balanced equation, we can see that one mole of sulfuric acid reacts with one mole of magnesium carbonate to produce one mole of magnesium sulfate, one mole of carbon dioxide, and one mole of water.
The moles of magnesium carbonate at the start can be calculated from the number of moles of sulfuric acid that reacted with it, using the mole ratio from the balanced equation:
1 mole of MgCO₃ will reacts with 1 mole of H₂SO₄
Therefore, the number of moles of MgCO₃ is also 0.200 moles.
The mass of magnesium carbonate at the start can be calculated using its molar mass and the number of moles:
molar mass of MgCO₃ = 24.31 g/mol (for Mg) + 12.01 g/mol (for C) + 3(16.00 g/mol) (for 3 O) = 84.31 g/mol

which indicator would be the best to use for a titration between 0.30 m c6h5cooh with 0.30 m naoh? you will probably need to consult the appropriate table in the book.
The best indicator to be used is Phenolphthalein.
Phenolphthalein changes color from colorless to pink as the solution becomes basic, which is ideal for this titration as the endpoint is when all the benzoic acid has reacted with the sodium hydroxide to form sodium benzoate, which is basic.
It is important to note that the equivalence point for this titration is not at a pH of 7, as it would be for the titration of a strong acid with a strong base. Instead, the equivalence point for the titration of a weak acid with a strong base is above a pH of 7, closer to a pH of 8-10.
Hence, Phenolphthalein would be the best indicator to use for a titration between 0.30 M [tex]C_6H_5COOH[/tex] with 0.30 M NaOH.
