Answers
4.2228 g of solid potassium sulfide should be added to make an aqueous solution of 0.180 M potassium sulfide for an experiment in lab, using a 300 ml volumetric flask.
The given molarity of the aqueous solution of potassium sulfide is 0.180 M and the volume of the solution is 300 mL. We are required to find out the amount of solid potassium sulfide required to make the solution.
The formula to calculate the number of moles is: Number of moles = Molarity x Volume (in liters) 1. Convert the volume into liters.300 mL = 0.3 L2. Substitute the given values in the above formula.Number of moles = 0.180 M x 0.3 LNumber of moles = 0.054 mol3. The molecular formula of potassium sulfide is K2S. It means there are two moles of K for one mole of K2S. Hence, we can calculate the moles of K.Number of moles of K = 2 x 0.054
Number of moles of K = 0.108 mol4. The molar mass of K is 39.1 g/mol. Hence, we can calculate the mass of K required to make 0.108 mol.Number of grams of K = Number of moles x Molar massNumber of grams of K = 0.108 mol x 39.1 g/mol
Number of grams of K = 4.2228 g. Hence, 4.2228 g of solid potassium sulfide should be added to make an aqueous solution of 0.180 M potassium sulfide for an experiment in lab, using a 300 ml volumetric flask.

Answers
The correct answer is
Option C.
they generally exist as zwitterions at physiological ph.
What is zwitterions ?
A zwitterion, also known as an inner salt or a dipolar ion, is a molecule that has an equal number of positively and negatively charged functional groups. The word "zwitterion" comes from the German word "hermaphrodite" (tsvt). [2] A chemical equilibrium will be created between the "parent" molecule and the zwitterion in a solution of amino acids, for instance.
Because the positive charge is on a quaternary ammonium group, betaines are zwitterions that cannot isomerize to an all-neutral form. A molecule with both a carboxylate group and a phosphonium group cannot isomerize, either.
The amino acid is the basic building block of proteins, consisting of a carboxyl, an amino, and a variable R-group. The R-group in amino acids is what makes them unique. The condensation reaction between the carboxyl group of one amino acid and the amino group of another amino acid results in the formation of a peptide bond between the two amino acids.

7. A balloon contains 39.4 mL of gas at a pressure of 741 torr. If the temperature does not
change, what is the volume of the gas at a pressure of 862 torr?
Answers
Answer:
34.0 mL.
Explanation:
The volume of a gas at constant temperature is inversely proportional to the pressure. We can use this relationship to find the new volume. Using the formula:
\(\sf:\implies{V1 \times P1 = V2 \times P2}\)
where V1 and P1 are the initial volume and pressure, and V2 and P2 are the final volume and pressure, respectively.
Plugging in the given values, we get:
\(\sf:\implies{V2 = V1 \times P1 / P2 = 39.4 mL}\)
\(\sf:\implies{39.4 mL \times 741 torr / 862 torr = 34.0 mL}\)
So, the volume of the gas at a pressure of 862 torr is 34.0 mL.

Calculate the volume of oxygen that was in excess. if 150cm³ of carbon(11) oxide burns in 80cm³of oxygen according to the following equation 2CO + O2 =2CO.
Answers
If 150cm³ of carbon(11) oxide burns in 80cm³of oxygen according to the given equation the volume of oxygen that was in excess is 5.6 cm³.
From the balanced equation, we can see that 2 moles of CO react with 1 mole of O2. Therefore, we need to determine how much O2 is required to react with 150 cm³ of CO.
Let's start by calculating the number of moles of CO:
n(CO) = V(CO) / molar volume at STP
= 150 cm³ / 22.4 L/mol
= 0.006696 mol
Since the stoichiometric ratio of equation of CO to O2 is 2:1, we need half as many moles of O2 as CO. Therefore, the number of moles of O2 required is:
n(O2) = 1/2 * n(CO)
= 1/2 * 0.006696 mol
= 0.003348 mol
Now we can calculate the volume of oxygen required using the ideal gas law:
PV = nRT
Assuming the temperature and pressure are constant, we can simplify this to:
V = n(RT/P)
where V is the volume of gas in liters, n is the number of moles of gas, R is the ideal gas constant, T is the temperature in Kelvin, and P is the pressure in atmospheres.
At STP, the temperature is 273 K and the pressure is 1 atm. Therefore:
V(O2) = n(O2)(RT/P)
= 0.003348 mol * (0.0821 L·atm/mol·K * 273 K / 1 atm)
= 0.0744 L
= 74.4 cm³
So the volume of oxygen required to react with 150 cm³ of CO is 74.4 cm³. Since the initial volume of O2 was 80 cm³, the volume of O2 in excess is:
V(excess) = V(initial) - V(required)
= 80 cm³ - 74.4 cm³
= 5.6 cm³
Therefore, the volume of oxygen that was in excess is 5.6 cm³.

1000 grams of nitroglycerin 2% ointment should be mixed with the ointment base to obtain 100 grams of an ointment with a concentration of 0.2%.
To determine the amount of nitroglycerin 2% ointment needed to mix with an ointment base to obtain 100 grams of an ointment with a concentration of 0.2%, we can use the concept of a proportion.
Let's set up the proportion:
(grams of nitroglycerin 2% ointment) / 2% = 100 grams / 0.2%
To solve for the grams of nitroglycerin 2% ointment, we can cross-multiply and then divide:
(grams of nitroglycerin 2% ointment) = (2% / 0.2%) * 100 grams
Calculating the right side of the equation:

Answers
The theoretical yield of 18 gram of \(H_{2}\) is 162 gram of \(H_{2} O\) .
The amount of a product produced by a reaction is generally expressed as a percentage of the reaction's yield. The amount of product that stoichiometry predicts is known as the theoretical yield, but the amount that would be actually achieved is known as the actual yield.
The balanced chemical equation is :
\(2H_{2} +O_{2}\) → \(2H_{2} O\)
It is known that the molar mass of water is 18 gram /mol and 2 gram per mole of \(H_{2}\).
18g \(H_{2}\) (1 mol \(H_{2}\) (/2 g \(H_{2}\) ()(2 mol \(H_{2} O\) / 2 mol \(H_{2}\) ()(18 g \(H_{2} O\) /1 mol \(H_{2} O\) ) = 162 g \(H_{2} O\) .
Theoretical yield will be 162 gram.

Answers
Answer:
A. 70 K
B. 3.16 atm
Explanation:
We'll begin by calculating the number of mole in 175 g of Ar. This can be obtained as follow:
Mass of Ar = 175 g
Molar mass of Ar = 40 g/mol
Mole of Ar =?
Mole = mass / molar mass
Mole of Ar = 175 / 40
Mole of Ar = 4.375 moles
A. Determination of the temperature.
Mole of Ar (n) = 4.375 moles
Volume (V) = 2.50 L
Pressure (P) = 10 atm
Gas constant (R) = 0.0821 atm.L/Kmol
Temperature (T) =?
PV = nRT
10 × 2.5 = 4.375 × 0.0821 × T
25 = 4.375 × 0.0821 × T
Divide both side by (4.375 × 0.0821)
T = 25 / (4.375 × 0.0821)
T ≈ 70 K
B. Determination of the pressure.
Mole of Ar (n) = 4.375 moles
Volume (V) = 2.50 L
Temperature (T) = 22 K
Gas constant (R) = 0.0821 atm.L/Kmol
Pressure (P) =?
PV = nRT
P × 2.5 = 4.375 × 0.0821 × 22
Divide both side by 2.5
P = (4.375 × 0.0821 × 22) / 2.5
P = 3.16 atm.

(a) - 1.39 atm is the partial pressure of the hydrogen gas in the sample

What exactly is the partial pressure law?According to Dalton's Law, often known as the Legislation of Partial Pressures, the combined pressure of a mix of gas is equal to the product of their individual partial pressures.
Briefing:(a)The partial pressure of hydrogen gas and the vapour pressure of water are added to determine the total pressure of the gas mixture.
PT = Pw + PH
Water has a vapour pressure of atm.
Pw = (30.75 torr)(1.00 atm) / 760 torr
Pw = 0.0405 atm
The hydrogen gas pressure is
PH = PT - Pw
PH = 1.44 atm - 0.0405 atm
PH = 1.39 atm
(b) The amount of hydrogen gas in moles is
n = PV / RT
n = (1.39 atm) (0.2384 L) / 0.82057 atm L / mol K (302.6 K)

(b)How many grams of aluminum must have reached to produce this quantity of hydrogen gas ? The vapor pressure of water at 29.4 ∘c is 30.75 torr.
i have added 4 l of air to a balloon at sea level (1.0 atm). if i take the balloon with me to the top of mount everest, where the air pressure is 0.30 atm, what will the new volume of the balloon be?
Answers
The new volume of the balloon at the top of Mount Everest, where the air pressure is 0.30 atm, will be approximately 13.33 liters.
The new volume of the balloon at the top of Mount Everest, where the air pressure is 0.30 atm, can be determined using Boyle's law. Boyle's law states that the pressure and volume of a gas are inversely proportional,given a constant temperature.
Mathematically, Boyle's law can be expressed as:
P₁V₁ = P₂V₂
Where:
P₁ = Initial pressure (1.0 atm)
V₁ = Initial volume (4 L)
P₂ = Final pressure (0.30 atm)
V₂ = Final volume (unknown)
By substituting the known values into the equation and solving for V₂, we can determine the new volume of the balloon:
(1.0 atm) * (4 L) = (0.30 atm) * V₂
4 L = 0.30 atm * V₂
V₂ = (4 L) / (0.30 atm)
V₂ ≈ 13.33 L. Therefore, the new volume of the balloon at the top of Mount Everest, where the air pressure is 0.30 atm, will be approximately 13.33 liters.
