I think the correct answer from the choices listed above is option C. The statement that best explains why a crystal is incompressible would be that there is little, if any, space left between its adjacent molecules. Hope this answers the question. Have a nice day.

Answer: Option (C) is the correct answer.

Explanation:

A crystal is a solid substance and it is known that in solids, molecules are held together by strong intermolecular forces of attraction.

As a result, the atoms of a solid substance are not able to move from their initial position but they can vibrate at their mean position due to very little space between its adjacent atoms.

Hence, a solid substance in incompressible in nature and it has a definite shape and volume.

Thus, we can conclude that the statement there is little, if any, space left between its adjacent molecules.

The graph below shows how the temperature and volume of a gas vary when the number of moles and the pressure of the gas are held

DedPeter [7]

Answer:

Option C. By increasing the temperature

Explanation:

From the graphical illustration above, we see clearly that the volume and temperature of the gas are directly proportional. This implies that as the temperature increases, the volume will also increase and as the temperature decreases, the volume will also decrease. This can further be explained by using the ideal gas equation as shown below:

PV = nRT

P is the pressure.

V is the volume.

n is the number of mole.

R is the gas constant.

T is the temperature.

PV = nRT

Divide both side by P

V = nRT/P

Since n and P are constant, the equation above becomes:

V & T

V = KT

K is the constant.

The above equation i.e V = KT implies that:

As T increases, V will also increase and as T decreases, V will also decrease.

Considering the question given above,

The volume of the gas can be increased if the temperature is increased.

Enter your answer in the provided box. what is the emf of a cell consisting of a pb2 / pb half-cell and a pt / h / h2 half-cell

sp2606 [1]

Answer:

The emf of the electrochemical cell has been calculated to be <u>3.364.</u>

in order to calculate the emf we need to apply Nernst equation.

The emf has been the potential of the cell in the reaction with the change in the electrons in the reaction. The emf of the cell has been given by the Nernst equation as -

emf= E⁰ cell - 0.059/n. log 1/concentration

Computation for the emf of the cell

The given cell has the number of electrons transfer, n= 2

The concentration of Pb2= 0.57 M

The concentration of H= 0.090 M

The cell potential of the reaction has been= -0.126

Substituting the values for the emf of the cell:

emf= -0.126- 0.059/2 * log 1/ [0.57]x [0.090] ²

emf= 1.555* 2.337

emf=3.634 v

The emf of the electrochemical cell has been calculated to be 3.634 v.
