A sample of hydrogen gas at a pressure of 0.520 atm and a temperature of 26.2°C, occupies a volume of 15.4 liters. If the gas is
Oksanka [162]

Answer:

1.99 atm

Explanation:

Step 1:

Data obtained from the question. This include the following:

Initial pressure (P1) = 0.520 atm

Initial temperature (T1) = 26.2°C

Initial volume (V1) = 15.4L

Final temperature (T2) = constant = 26.2°C

Final volume (V2) = 4.02L

Final pressure (P2) =..?

Step 2:

Determination of the new pressure of the gas.

Since the temperature of the gas is constant, it means the gas is obeying Boyle's law. Thus, the new pressure of the gas can be obtained by applying the Boyle's law equation as shown below:

P1V1 = P2V2

0.520 x 15.4 = P2 x 4.02

Divide both side by 4.02

P2 = (0.520 x 15.4) / 4.02

P2 = 1.99 atm

Therefore, the new pressure of the gas is 1.99 atm

An unknown quantity of methane gas, CHA, is held in a 2.00-liter container at 77°C. The pressure inside the container is 3.00 am
kolbaska11 [484]

Answer:

0.21\text{ mol}

Explanation:

Here, we want to calculate the number of moles of methane in the container

From the ideal gas law:

\begin{gathered} PV\text{ = nRT} \\ n\text{ = }\frac{PV}{RT} \end{gathered}

where:

P is the pressure inside the container which is 3 atm

V is the volume of the container which is 2 L

R is the molar gas constant which is 0.0821 Latm/mol.k

T is the temperature in Kelvin (we convert the temperature in Celsius by adding 273 : 273 + 77 = 350 K)

n is the number of moles that we want to calculate

Substituting the values, we have it that:

n=\text{ }\frac{3\times2}{0.0821\text{ }\times350}\text{ = 0.21 mol}

When a disulfide linkage is formed, the compound containing this new linkage has been __________?
gregori [183]
<h3>Answer:</h3>

            When a disulfide linkage is formed, the compound containing this new linkage has been <u>oxidized</u>.

<h3>Explanation:</h3>

                   Oxidation reaction is defined as,

i) Addition of Oxygen Atoms:

                                   When oxygen atom is added to any compound, then the compound is said to be oxidized and the reaction is known as oxidation reaction.

Example:

Oxidation of Alcohols into carboxylic acids:

                                   R---CH₂--OH         →         R---COOH

ii) Removal of Hydrogen Atoms:

                                                    When hydrogen atom(s) are removed from any compound, then the compound is said to be oxidized and the reaction is also called as oxidation reaction.

Example:

Formation of disulfide bond fro thiols:

                                 R--S-H  +  R--S-H      →       R---S--S---R

Disulfide bond is quite popular in protein chemistry where it is formed in cystine from cystein amino acids.
