Answer:

According to Kinetic Molecular theory, Temperature is directly proportional to the Average Kinetic energy of a molecules.

Explanation:

If the mass of the particles in a container is constant, then its moving molecules cause the gas gets warmer. On collision of molecules, Kinetic energy of molecules get high, so as a result, temperature gets high.

Fast moving of particles increases the temperature.

32. Explain why carbon shows versatile nature why it forms so many organic compounds.​
anyanavicka [17]

Answer:

Carbon is a versatile element and is found in many different chemical compounds, including those found in space. Carbon is versatile because it can form single, double, and triple bonds. It can also form chains, branched chains, and rings when connected to other carbon atoms.

Explanation:

meaning of versatile: capable of or adapted for many different uses, skills, etc. 2 variable or changeable.

The versatile nature of carbon can be best understood with its features such as, tetravalency and catenation. In this section let us learn more about versatility of carbon.

Carbon is a versatile element and is found in many different chemical compounds, including those found in space. Carbon is versatile because it can form single, double, and triple bonds. It can also form chains, branched chains, and rings when connected to other carbon atoms.

The two characteristic features seen in carbon, that is, tetravalency and catenation, put together give rise to a large number of compounds. Many have the same non-carbon atom or group of atoms attached to different carbon chains.

Catenation: The property of forming long chains by self-linking with other carbon atoms to form long chains, rings, double or triple bonds is called catenation.

Isomerism: Compounds with same molecular formula but different structural formula are called isomers. An isomerism commonly seen is due to difference in the arrangement of atoms or groups of atoms & is called structural isomerism. The 4 types of structural isomerism are:

 Chain isomerism

 Position

 Functional

Metamerism

Tetravalency: Carbon has 4 electrons in its valence shell. Energy considerations do not allow it to gain or lose 4 electrons; therefore it forms covalent bonds with other elements to complete its octet. This accounts for its tetravalency and explains its ability to form a variety of compounds.

At 800 K, the equilibrium constant, Kp, for the following reaction is 3.2 × 10–7. 2 H2S(g) ⇌ 2 H2(g) + S2(g) A reaction vessel a
djverab [1.8K]

Answer:

0.008945 atm

Explanation:

In the reaction:

2H2S(g) ⇌ 2 H2(g) + S2(g)

Kp is defined as:

Kp = P_{H_{2}}^2P_{S_{2}} / P_{H_{2}S}^2

<em>Where P is the pressure of each compound in equilibrium.</em>

If initial pressure of H2S is 3.00atm, concentrations in equilibrium are:

H2S = 3.00 atm - 2X

H2 = 2X

S2: = X

Replacing:

3.2x10^{-7} = (2X)^2X / (3-2X)^2

3.2x10^{-7} = 4X^3 / 9- 6X+4X^2

0 = 4X³ - 1.28x10⁻⁶X² + 1.92x10⁻⁶X - 2.88x10⁻⁶

Solving for X:

X = 0.008945 atm

As in equilibrium, pressure of S2 is X, <em>pressure is 0.008945 atm</em>

What mass of Cu(s) is electroplated by running 30.0 A of current through a Cu2 (aq) solution for 4.00 h
Alborosie

Answer:

The correct answer is "142 g".

Explanation:

According to the question,

⇒ Cu^2+(aq)+2e^  ------> Cu(s)

where,

Z = 2

F = 96500c

C = 30 A

t = 4h

 = 4\times 60\times 60

 = 14400 \ sec

We know that,

Atomic mass of Cu(M) = 63.5 g/mole

Now,

⇒ W=\frac{Mct}{ZF}

On putting the values, we get

        =\frac{63.5\times 30\times 14400}{2\times 96500}

        =\frac{27432000}{193000}

        =142 \ g

The information that is most useful to determine which will have a lower freezing point is the van't Hoff factor of each solute. It is the number of ions that is ionized when the solute are in solution. The higher this value, the lower is the freezing point of the solution given they have the same concentration.
