How will increasing the pressure on the system affect this equilibrium reaction? 2H2(g)+O2(g) -> 2H2O(g)

A sample of a gas occupies 2.76 L at 303K. What would the volume be if the temperature was increased to 404K? Assume constant

Artist 52 [7]

Answer:

If the temperature was increased to 404 K, its volume would be 3.68 L.

Explanation:

Charles' Law gives a relationship between the volume and the temperature of the gas at constant temperature. This law states that the volume of a given amount of gas held at constant pressure is directly proportional to the temperature.

$V\propto T$

$\dfrac{V_1}{V_2}=\dfrac{T_1}{T_2}$

Let

$V_1=2.76\ L\\\\T_1=303\ K\\\\T_2=404\ K$

Let $V_2$ is new volume. Using above formula we get :

$V_2=\dfrac{V_1T_2}{T_1}\\\\V_2=\dfrac{2.76\times 404}{303}\\\\V_2=3.68\ L$

If the temperature was increased to 404 K, its volume would be 3.68 L.

Solid potassium chlorate decomposes upon heating to form

olga55 [171]

Answer:

32.6%

Explanation:

Equation of reaction

2KClO₃ (s) → 2KCl (s) + 3O₂ (g)

Molar mass of 2KClO₃ = 245.2 g/mol ( 122.6 × 2)

Molar volume of Oxygen at s.t.p = 22.4L / mol

since the gas was collected over water,

total pressure = pressure of water vapor + pressure of oxygen gas

0.976 = 0.04184211 atm + pressure of oxygen gas at 30°C

pressure of oxygen = 0.976 - 0.04184211 = 0.9341579 atm = P1

P2 = 1 atm, V1 = 789ml, V2 = unknown, T1 = 303K, T2 = 273k at s.t.p

Using ideal gas equation

$\frac{P1V1}{T1}$ = $\frac{P2V2}{T2}$

V2 = $\frac{P1V1T2}{T1P2}$

V2 = 664.1052 ml

245.2 yielded 67.2 molar volume of oxygen

0.66411 will yield = $\frac{245.2 * 0.66411}{67.2}$ = 2.4232 g

percentage of potassium chlorate in the original mixture = $\frac{2.4232 * 100}{7.44}$ = 32.6%

Predict the effect (if any) of an increase in temperature on the electrical conductivity of

muminat

The electrical conductivity of a conductor increases with increasing temperature

An electrical current flows through a conductor because it provides little to no resistance to the movement of electrons. Typically, good electrical conductors include metals, metal alloys, electrolytes, even some nonmetals like graphite and liquids like water.

Metals, aqueous salt solutions (ionic chemicals dissolved in water), graphite, and the human body are a few examples of conductors.

A conductor makes it simple for current to flow through it. Insulators prevent electricity from passing through them. On the surface of conductors, there is an electric charge. In an insulator, there are no electric charges. Keeping conductors in a magnetic field prevents them from storing energy.

1.______ structure is achieved when a protein folds into a compact, three-dimensional between side-chain R groups of amino acids

kondor19780726 [428]

Answer:

The answer to your question is:

Explanation:

1._Terciary__ structure is achieved when a protein folds into a compact, three-dimensional between side-chain R groups of amino acids.

2._Primary___ structure is the sequence of amino acids in a protein.

3._Secondary___ structure describes the alpha helices and beta-sheets that are formed by hydrogen bonding between backbone atoms located near each other in the polypeptide chain.

4._Quaternary___ structure is the result of two or more protein subunits assembling to form a larger, biologically active protein complex.
