Calculate the amount of 0.1 M acid needed to neutralize 10,000 liters of pH 8.0 water. The acid is Sulfuric Acid - H2SO4 Show your work for brainliest

Answers

Answer 1

Answer:

0.963

Explanation:

Answer 2

pH is the potential of hydrogen that can be determined by the hydrogen or hydroxide ion concentration. 10 mL is the amount required of 0.1 M to neutralize.

What is pH?

pH estimates the acidic and the basicity of the solution when a solute is dissolved in the solvent.

Sulfuric acid is dissociated as:

H₂SO₄(aq) ⇌ H⁺(aq) + HSO₄⁻(aq)

pH is calculated as:

pH = -log [H⁺]

[H⁺] = 1x10⁻⁸ M

The moles in 10,000 L is, 10000L × 1x10⁻⁸  = 0.0001 moles

Moles of sulfuric acid required:

0.0001 moles × ( 1 mol H2SO4 ÷ 1 mol H⁺) = 0.001 moles

Further, volume is calculated as:

0.001 ×  (1L ÷ 0.1moles) = 0.01 L

Therefore, 10 mL of 0.1 M acid is needed to neutralize.

Fecal coliform increases the amount of organic substances in water and lowers the amount of dissolved oxygen, killing fish.​

Answers

Answer:

Fecal coliform increases the amount of organic substances in water and lowers the amount of dissolved oxygen, killing fish.​

Explanation:

Fecal coliform are species of bacteria that are found in the intestine of warm-blooded animals like humans etc. Hence, they are released whenever they excrete feaces. Due to this reason, the presence of fecal coliform bacteria in a water body indicates fecal discharge into that water.

The presence of excessive fecal coliform in a water body increases the amount of organic substances in the water. These organic substances are decomposed by bacteria, which causes the oxygen present in the water body (dissolved oxygen) to deplete/decrease. The depletion of oxygen in the water threatens aerobic aquatic organisms e.g fishes and they ultimately suffocate and die.

Oxygen bodyworkers origins of substations in water and lowers in the amount of dissolve the oxygen killing fish but it’s all gonna be OK because the carbon dioxide equals to killing fish drinking water so you don’t have a C stroke

Which energy profile best shows that the enthalpy of formation of CS2 is 89.4 KJ/mol?

Answers

Answer:

Option C. Energy Profile D

Explanation:

Data obtained from the question include:

Enthalpy change ΔH = 89.4 KJ/mol.

Enthalpy change (ΔH) is simply defined as the difference between the heat of product (Hp) and the heat of reactant (Hr). Mathematically, it is expressed as:

Enthalpy change (ΔH) = Heat of product (Hp) – Heat of reactant (Hr)

ΔH = Hp – Hr

Note: If the enthalpy change (ΔH) is positive, it means that the product has a higher heat content than the reactant.

If the enthalpy change (ΔH) is negative, it means that the reactant has a higher heat content than the product.

Now, considering the question given, the enthalpy change (ΔH) is 89.4 KJ/mol and it is a positive number indicating that the heat content of the product is higher than the heat content of the reactant.

Therefore, Energy Profile D satisfy the enthalpy change (ΔH) for the formation of CS2 as it indicates that the heat content of product is higher than the heat content of the reactant.

Answers

Answer:

Hey there!

In a covalent bond, both atoms share their electrons.

Hope this helps :)

The correct statement is that in a covalent bond, both atoms share their electrons. The correct answer is A. Both atoms share their electrons.

In a covalent bond, both atoms share their electrons to achieve a more stable electron configuration. Covalent bonds occur between nonmetal atoms, and they involve the sharing of electron pairs between the participating atoms. This sharing allows both atoms to achieve a more complete octet (or duet for hydrogen) in their outermost energy level.

Unlike ionic bonds, where one atom transfers electrons to another, covalent bonds involve a mutual sharing of electrons. This sharing can be equal (nonpolar covalent) or unequal (polar covalent) depending on the electronegativity difference between the atoms involved.

Option B, "One atom accepts electrons from another," is not characteristic of a covalent bond. That description aligns more with an ionic bond, where one atom donates electrons to another, resulting in the formation of charged ions.

Option C, "The atoms attract each other but their electrons do not interact," does not accurately describe a covalent bond. In a covalent bond, the sharing of electrons is the basis of the interaction between atoms, and the electrons of both atoms do interact and participate in the bond formation.

Therefore, the correct statement is that in a covalent bond, both atoms share their electrons.

Calculate the number of g of KCN that will react with 1.06 mol of HCl.

Answers

Answer:

68.9 g of KCN.

Explanation:

We'll begin by writing the balanced equation for the reaction. This is given below:

KCN + HCl → KCl + HCN

From the balanced equation above,

1 mole of KCN reacted with 1 mole of HCl.

Next, determination of the number of mole of KCN needed to react with 1.06 moles HCl.

This is illustrated below:

From the balanced equation above,

1 mole of KCN reacted with 1 mole of HCl.

Therefore, 1.06 moles of KCN will also react with 1.06 moles of HCl.

Finally, we shall convert 1.06 moles of KCN to grams.

This can be obtained as follow:

Molar mass of KCN = 39 + 12 + 14 = 65 g/mol.

Mole of KCN = 1.06 moles

Mass of KCN =...?

Mole = mass /Molar mass

1.06 = mass of KCN / 65

Cross multiply

Mass of KCN = 1.06 x 65

Mass of KCN = 68.9 g

Therefore, 68.9 g of KCN is needed to react with 1.06 moles of HCl.

What is solubility?

Solubility is defined as the ability of a substance which is basically solute to form a solution with another substance. There is an extent to which a substance is soluble in a particular solvent. This is generally measured as the concentration of a solute present in a saturated solution.

The solubility mainly depends on the composition of solute and solvent ,its pH and presence of other dissolved substance. It is also dependent on temperature and pressure which is maintained.Concept of solubility is not valid for chemical reactions which are irreversible. The dependency of solubility on various factors is due to interactions between the particles, molecule or ions.

Answers

Answer:

electrons move around the nucleus in fixed orbits of equal amounts of energy

Explanation:

To see the number of atoms of an element in a given molecule we need to multiply stoichiometry to the number that is written on the foot of the element that is stoichiometry. The correct option is option B.

What is atom?

Atom is the smallest particle of any element, molecule or compound. Atom can not be further divided. Atoms contains nucleus in its center and electron that revolve around the atom in fixed orbit.

In the nucleus, proton and neutron are present. Electron has -1 charge while proton has +1 charge. Neutron is neutral that is it has no charge. So overall the charge of nucleus is due to only proton, not by neutron.

Tartaric acid, C4H6O6, has the first ionization constant with the value: Ka1 = 9.20 × 10-4. Calculate the value of pKb for the conjugate base of tartaric acid. 10.963 3.036 1.087 x 10-11 9.20 x 10-4

Answers

Answer:

pKb = 10.96

Explanation:

Tartaric acid is a dyprotic acid. It reacts to water like this:

H₂Tart  +  H₂O  ⇄  H₃O⁺   +  HTart⁻         Ka1

HTart⁻  +  H₂O  ⇄  H₃O⁺   +  Tart⁻²           Ka2

When we anaylse the base, we have

Tart⁻²   +  H₂O  ⇄  OH⁻  +  HTart⁻       Kb1

HTart⁻  +  H₂O  ⇄  OH⁻  +    H₂Tart          Kb2

Remember that Ka1 . Kb2  = Kw, plus pKa1 + pKb2 = 14

Kb2 = Kw / Ka1  →   1×10⁻¹⁴ / 9.20×10⁻⁴  = 1.08×10⁻¹¹

so pKb = - log Kb2   → - log 1.08×10⁻¹¹ = 10.96

0.233L
4.41L
23.3 L
3.76 L
3.07 L

Answers

Answer:

3.07L

Explanation:

Charles law, which describes the direct relationship of the absolute temperature to its volume when the pressure is kept constant will be used in this case. The Charles' law equation is:

V1/T1 = V2/T2

Where; V1 is the volume of the gas at an initial state= 2.33L

V2 is the volume of the gas at a final state= ?

T1 is the absolute temperature of the gas at an initial state= 10°C

T2 is the absolute temperature of the gas at a final state= 100°C

The temperature in degree Centigrade (°C) must be converted to the absolute temperature unit (Kelvin) using:

T(K) = T(°C) + 273.15

T1 = 10°C + 273.15 = 283.15K

T2 = 100°C + 273.15 = 373.15K

To solve for V2 in the above Charles law equation, we make V2 the subject of the formula by saying:

V2 = V1 × T2 / T1

V2 = 2.33 × 373.15 / 283.15

V2 = 869.4395/ 283.15

V2 = 3.0705

Hence, the gas will be expanded to a volume of 3.07L when heated from 10.0°C to 100.0°C.
