Calculate the pH and the equilibrium concentration of S²- in a 6.89x10-2 M hydrosulfuric acid solution, H₂S (aq). For H₂S, Ka1 = 1.0x10-7 and Ka_2 = 1.0×10-1⁹ pH = [S²] = M
Therefore, the pH and the equilibrium concentration of S²⁻ in a 6.89x10⁻² M hydrosulfuric acid solution are pH = 7.78 and [S²⁻] = 2.31x10⁻¹¹ M.
Hydrosulfuric acid (H₂S) is a weak acid that dissociates in water to produce hydrogen ions (H⁺) and bisulfide ions (HS⁻). H₂S(aq) + H₂O(l) ⇌ H₃O⁺(aq) + HS⁻(aq)
The bisulfide ions (HS⁻) in turn reacts with water to produce hydronium ions (H₃O⁺) and sulfide ions (S²⁻).
HS⁻(aq) + H₂O(l) ⇌ H₃O⁺(aq) + S²⁻(aq) Ka1
= 1.0x10⁻⁷,
Ka2 = 1.0x10⁻¹⁹
To calculate the pH and the equilibrium concentration of S²⁻ in a 6.89x10⁻² M H₂S(aq) solution, we must first determine if H₂S(aq) is a strong or weak acid.
It has Ka1 = 1.0x10⁻⁷, which is a very small value; thus, we can conclude that H₂S(aq) is a weak acid.
To calculate the equilibrium concentration of S²⁻ in a 6.89x10⁻² M H₂S(aq) solution, we need to use the Ka2 value (Ka2 = 1.0x10⁻¹⁹) and a chemical equilibrium table.
[H₂S] = 6.89x10⁻² M[H₃O⁺] [HS⁻] [S²⁻]
Initial 0 0 0Change -x +x +x
Equilibrium (6.89x10⁻² - x) x xKa2 = [H₃O⁺][S²⁻]/[HS⁻]1.0x10⁻¹⁹
= x² / (6.89x10⁻² - x)
Simplifying: 1.0x10⁻¹⁹ = x² / (6.89x10⁻²)
Thus: x = √[(1.0x10⁻¹⁹)(6.89x10⁻²)]
x = 2.31x10⁻¹¹ M
Thus, [S²⁻] = 2.31x10⁻¹¹ M
To calculate the pH of the solution, we can use the Ka1 value and the following chemical equilibrium table.
[H₂S] = 6.89x10⁻² M[H₃O⁺] [HS⁻] [S²⁻]
Initial 0 0 0
Change -x +x +x
Equilibrium (6.89x10⁻² - x) x x
Ka1 = [H₃O⁺][HS⁻]/[H₂S]1.0x10⁻⁷
= x(6.89x10⁻² - x) / (6.89x10⁻²)
Simplifying: 1.0x10⁻⁷ = x(6.89x10⁻² - x) / (6.89x10⁻²)
Thus: x = 1.66x10⁻⁸ M[H₃O⁺]
= 1.66x10⁻⁸ M
Then, pH = -log[H₃O⁺]
= -log(1.66x10⁻⁸)
= 7.78 (rounded to two decimal places)

How many moles of hydrogen sulfide will react with 1moles of silver
If we have 1 mole of silver, we would need 0.5 moles of hydrogen sulfide to completely react with the silver.
Hydrogen sulfide (H₂S) is a colorless, flammable gas that has a strong odor of rotten eggs. It is a naturally occurring gas that is produced by the decay of organic matter and can be found in crude petroleum and natural gas deposits, volcanic gases, and hot springs. Hydrogen sulfide is also produced by human and animal wastes and is a byproduct of some industrial processes.
Hydrogen sulfide is toxic and can be deadly in high concentrations. It can cause irritation of the eyes, nose, and throat at low concentrations, and at higher concentrations, it can cause unconsciousness, coma, and death.
In addition to its toxic properties, hydrogen sulfide is also flammable and can form explosive mixtures with air. Despite its dangers, hydrogen sulfide has some uses in industry, such as in the production of sulfuric acid and in the refining of petroleum.
Balanced chemical equation for the reaction of hydrogen sulfide (H₂S) and silver (Ag) is:
2Ag + H₂S → Ag₂S + H₂
From the equation, we can see that 2 moles of silver reacts with 1 mole of hydrogen sulfide. Therefore, if we have 1 mole of silver, we would need 0.5 moles of hydrogen sulfide to completely react with the silver.

Acid protonates the hydroxyl group and conjugate base deprotonates the beta carbon or adjacent carbon, which leads to formation of a pi bond between the alpha and beta carbon.
What is an acid?
A Brnsted-Lowry acid or Lewis acid is a molecule or ion that may either donate a proton (the hydrogen ion, H+) or establish a covalent bond with an electron pair. Proton donors, also known as Brnsted-Lowry acids, are the first class of acids. Proton donors, sometimes referred to as Arrhenius acids, generate the hydronium ion H3O+ under the unique situation of aqueous solutions. The Arrhenius hypothesis was expanded upon by Brnsted and Lowry to take non-aqueous solvents into account. A hydrogen atom is often bound to a chemical structure in a Brnsted or Arrhenius acid that is still energetically advantageous after the loss of H+.

How do I convert milliliters to Liters?
To convert milliliters (mL) to liters (L), you need to divide the milliliter value by 1000, as there are 1000 milliliters in one liter.
Here's the formula for converting milliliters to liters:
Liters = Milliliters / 1000
For example, if you have 5000 milliliters, the conversion to liters would be:
Liters = 5000 mL / 1000 = 5 L
So, 5000 milliliters is equivalent to 5 liters.

According to the information, in general, adding electrons to nonmetals is called reduction.
Nonmetals are elements in the periodic table that are generally not very reactive chemically.
In general, nonmetals have a low melting and boiling point, are poor conductors of heat and electricity, and have a tendency to gain electrons when they react with other elements.
Nonmetals typically form negative ions (anions) when they react with metals, which means they gain electrons.
This is called reduction, which occurs when electrons are added to an atom, reducing its oxidation state or oxidation number.
Additionally, nonmetals often form covalent bonds with other nonmetals by sharing electrons to form molecules.
This is in contrast to metals, which typically form ionic bonds by transferring electrons to form cations and anions.

Decide whether each proposed multiplication or division is possible from the image below and restore the results if they are I don’t need an explanation just the answer please
The question presents a table with many multiplications using different units (mass and velocity) and requires us to decide whether the operations presented are possible.
To solve this question, we should keep in mind this general rule: for units reffering to the same measurement (for example: mass, volume, distance etc.), we are able to multiply the units as long as they are the same. For example: g x g, L x L, m x m. If units are about the same measurement but still different, we should convert one of them in order to make them the same.
On the other hand, when we are talking about division, if we have the same unit on the operator and denominator position, we will have a result as "1" - then we need to analyze the entire value.
Now, considering the operations presented in the question:
On the first one, we have kg multiplied by kg. Although it isn't usual to see square kg (kg^2), we are able to make this operation:
\(9.0\text{ kg }\times5.0\text{ kg}=45kg^2\)On the second line, we have square g multiplied by kg. In this case, since the first unit is square, we can assume they are not about the same measurement. Thus, we can't complete this operation.
On the third line, there is a division and we should proceed as a normal operation (although the unit km/s isn't usual):
\(\frac{5.6\text{ km}}{7.0\text{ s}}=0.8\text{ km/s}\)In summary, the answers should be:
1) Is it possible? YES / Result = 45 kg^2
2) Is it possible? NO
3) Is it possible? YES / Result = 0.8 km/s
