The hydrogen ions from the acid react with the hydroxide ions from the base to form water. This reaction is also known as an acid-base neutralization reaction. The resulting solution is neutral, meaning that it has a pH of 7. The correct option is C.
When an acid is neutralized by a base, the resulting solution contains water and a salt.
In a neutral solution, the concentration of hydrogen ions (H⁺) is equal to the concentration of hydroxide ions (OH⁻). This means that the answer is C - always equal to the concentration of hydroxide ions. The equation for this reaction is:
HA + BOH → H₂O + BA
In this equation, HA represents an acid, BOH represents a base, H₂O represents water, and BA represents a salt.
The pH of a solution can be determined by calculating the concentration of hydrogen ions. If the concentration of hydrogen ions is greater than the concentration of hydroxide ions, the solution is acidic and has a pH less than 7. If the concentration of hydroxide ions is greater than the concentration of hydrogen ions, the solution is basic and has a pH greater than 7. In a neutral solution, the concentration of hydrogen ions is equal to the concentration of hydroxide ions, resulting in a pH of 7.

Using crystal field theory, the number of unpaired electrons in [Mn(NH₃)₆]²⁺ is three.
Using crystal field theory, we can determine the number of unpaired electrons in the complex ion [Mn(NH₃)₆]²⁺+ as follows:
The complex ion consists of a central Mn²⁺ ion, which is surrounded by six NH₃ ligands. Mn²⁺ has an electron configuration of [Ar] 3d⁵, meaning it has five electrons in its d orbitals. The NH₃ ligands are considered weak field ligands, meaning they cause a small energy difference between the d orbitals.
In weak field complexes, the electrons preferentially occupy the lower energy orbitals in a way that maximizes the number of unpaired electrons (Hund's rule). In an octahedral complex, such as [Mn(NH₃)₆]²⁺, the d orbitals are split into two groups: the t²g orbitals (dxy, dxz, dyz) and the eg orbitals (dz², dx²-y²). The t²g orbitals are lower in energy than the eg orbitals.
As there are five d electrons in Mn²⁺, they will first fill the t²g orbitals, with one electron each (following Hund's rule). This results in three unpaired electrons in the [Mn(NH₃)₆]²⁺ complex ion.

Methane (CH4) is used in laboratory burner. When 1 mole of methane burns at constant pressure, it produces 804 kJ of heat and does 3 kJ of work.1. What is the value of ÎHÂ for the combustion of one mole of methane?2. What is the value of ÎEÂ for the combustion of one mole of methane?
The answers are 1. the value of ΔH° for the combustion of one mole of methane is -801 kJ/mol and 2. the value of ΔE° for the combustion of one mole of methane is also -801 kJ/mol.
1. The value of ΔH° for the combustion of one mole of methane can be calculated using the first law of thermodynamics:ΔH° = ΔE° + PΔVWhere ΔE° is the change in internal energy of the system, P is the pressure, and ΔV is the change in volume. Since the combustion is done at constant pressure, ΔV is equal to the volume of the gaseous products minus the volume of the gaseous reactants, which is negligible. Therefore, we can assume that ΔV is zero and simplify the equation to:ΔH° = ΔE° + PΔV = ΔE°Given that 1 mole of methane produces 804 kJ of heat and does 3 kJ of work, the change in internal energy can be calculated as:[tex]ΔE° = q + w = -804 kJ + 3 kJ = -801 kJ/mol[/tex]Therefore, the value of ΔH° for the combustion of one mole of methane is -801 kJ/mol.2. The value of ΔE° for the combustion of one mole of methane can be calculated using the same equation as above:[tex]ΔE° = q + w = -804 kJ + 3 kJ = -801 kJ/mol[/tex]Therefore, the value of ΔE° for the combustion of one mole of methane is also -801 kJ/mol.The difference between ΔH° and ΔE° is that ΔH° accounts for any work done by the system, while ΔE° only accounts for the change in internal energy of the system. In this case, since the work done is negligible compared to the heat produced, the values of ΔH° and ΔE° are almost identical.For more such question on combustion

The correct statement concerning galvanic (voltaic) cells and electrolytic cells is that external electric energy must be supplied to an electrolytic cell, while in a galvanic (voltaic) cell, the redox reaction is always spontaneous.
Galvanic cells produce electrical energy from a spontaneous redox reaction, where the anode undergoes oxidation and the cathode undergoes reduction. This flow of electrons generates an electrical current that can be used to power electronic devices. In contrast, electrolytic cells require an external source of electrical energy to drive a non-spontaneous redox reaction. The anode serves as the site of oxidation, and the cathode serves as the site of reduction. By supplying electrical energy, the reaction can proceed in the desired direction, producing a product that would not form spontaneously.
In summary, galvanic cells can serve as a source of electrical energy, while electrolytic cells require external electric energy to drive a non-spontaneous reaction. The cathode is the site of reduction in a galvanic (voltaic) cell, but the cathode is the site of oxidation in an electrolytic cell.

When a ketone and its enol are in equilibrium, under most conditions, the concentration of the enol is slightly higher than the concentration of the ketone. Option A is Correct.
This is because the enol is the less stable tautomer and therefore the equilibrium lies slightly towards the enol form.
The keto-enol tautomerism is the name of this chemical equilibrium. The enol tautomer and keto would quickly reach equilibrium. Additionally, because the keto form is more stable in this equilibrium, it predominates in the combination. Therefore, the enol's concentration would be lower than the keto's.
Even though enol suggests the presence of a double bond and a hydroxyl group, they carry a carbonyl bond. The stabilising components of both the keto and enol tautomers are necessary for the equilibrium of keto-enol tautomerization.
The enol that might have produced 2-pentanone was pent-1-en-2-ol. Equilibrium is not a very good depiction because it substantially favours the ketone.

λ= 35 nm (nanometers).
In summary, the frequency of ultraviolet light with a photon energy of 5.6610-18 J is 8.54 * 1015 Hz, and the corresponding wavelength is 35 nm. Ultraviolet light has a shorter wavelength and higher frequency than visible light, making it more energetic and potentially harmful to living organisms.

The charge on each atom is the same in reactants and products.C. the total number of ions is the same in reactants and products.D. the sum of the coefficients of the reactants is equal to the sum of the coefficients of the products.E. the number of atoms of each element is the same in reactants and products.
A chemical equation is balanced when E. the number of atoms of each element is the same in reactants and products because in a balanced chemical reaction the amount of reactants is equal to the amount of products.
A balanced chemical equation represents a chemical reaction with the same number of atoms of each element on both sides of the equation. In other words, the total mass and the number of atoms in the reactants are equal to those in the products.
The balance of the equation is achieved by adjusting the coefficients in front of the chemical formulas of the reactants and products to ensure that the same number of atoms of each element is present on both sides of the equation. Hence, option E is correct.
Balancing the chemical equation is important as it helps to predict the amount of reactants and products that will be used and formed, respectively, and it also ensures that the reaction follows the law of conservation of mass.

Amphiprotic species are those that can act as both an acid and a base in a chemical reaction. So, among the given options
(a) H₂O - amphiprotic
(b) S₂⁻ - amphiprotic
(d) HSO₄⁻ - amphiprotic
(e) CO₃²⁻ - amphiprotic
(a) H₂O can act as an acid by donating a proton (H⁺) and as a base by accepting a proton. For example, in the reaction with HCl, water acts as a base and accepts a proton to form H₃O⁺ and Cl⁻. The chemical equation for the amphiprotic character of water can be written as:
H₂O + HCl -> H₃O⁺ + Cl⁻
(b) S₂⁻ can also act as an acid and donate a proton, or as a base and accept a proton. For example, in the reaction with HCl, sulfide ion acts as a base and accepts a proton to form HS⁻ and Cl⁻. The chemical equation for the amphiprotic character of S₂⁻ can be written as:
S₂⁻ + HCl -> HS⁻ + Cl⁻
(d) HSO₄⁻ and CO₃²⁻ are also amphiprotic species. HSO₄⁻ can act as an acid and donate a proton or as a base and accept a proton. For example, in the reaction with NH₃, HSO₄⁻ acts as an acid and donates a proton to form NH₄⁺ and SO₄²⁻. The chemical equation for the amphiprotic character of HSO₄⁻ can be written as:
HSO₄⁻ + NH₃ -> NH₄⁺ + SO₄²⁻
(e) CO₃²⁻ can act as an acid and donate two protons or as a base and accept two protons. For example, in the reaction with HCl, CO₃²⁻ acts as a base and accepts two protons to form H₂CO₃ and Cl⁻. The chemical equation for the amphiprotic character of CO32- can be written as:
CO₃²⁻ + 2HCl -> H₂CO₃ + 2Cl⁻
Therefore, only H₂O, S₂⁻, HSO₄⁻, and CO₃²⁻ are amphiprotic species. a, b, d and e are the correct options.

Calculate the volume that 4.5 kg of ethylene gas (C₂H₂) will occupy at STP
Answer:
3, 876.9 ~ 3, 877
Explanation:
4.5 kg = 4500 g....... convert to gram
n =m/M , n= no of mol
m= mass of sub.
M= molar mass
so n= 4500g / 26g/mol
n= 173.076 mol
then 1 mol = 22.4 L ............... at STP
at STP 173.076 mol = X
then when u solve X by
X = (173.076 mol × 22.4 L)/ 1 mol
X = 3, 876.9 L at STP which is aproximate to
