Answer: Option (d) is the correct answer.

Explanation:

A catalyst is defined as the substance that helps in increasing the rate of a chemical reaction by lowering the activation energy. A catalyst never gets consumed in a chemical reaction.

When a catalyst lowers the activation energy then molecules with much less energy are also able to participate in the chemical reaction. Hence, formation of products occur rapidly and thus rate of reaction increases.

Therefore, we can conclude that the catalyst is unchanged and is separate from the products after a chemical reaction has occurred.

Describe what happens to an ionic compound when it has been fully dissolved in water

Marat540 [252]

When you immerse an ionic compound in water, the ions are attracted to the water molecules, each of which carries a polar charge. If the attraction between the ions and the water molecules is great enough to break the bonds holding the ions together, the compound dissolves.

What is the pressure of a sample of gas at a volume of .335 L if it occupies 1700 mL at 850 mm Hg?

dangina [55]

Answer:

Pressure = 4313.43mmHg

Explanation:

P1 = ?

V1 = 0.335L

V2 = 1700mL =1700*10^-3L = 1.7L

P2 = 850mmhg

From Boyle's law, the volume of a fixed mass of gas is inversely proportional to its pressure provided that temperature remains constant.

P = k / v

K = pv. P1V1 = P2V2 = P3V3 =........=PnVn

P1V1 = P2V2

Solve for P1,

P1 = (P2*V2) / V1

P1 = (850 * 1.7) / 0.335

P1 = 4313.43mmHg

The pressure of the gas was 4313.43mmHg

In an electrolytic cell, the magnitude of the standard cell potential is the:______

melamori03 [73]

Answer:

a. minimum voltage that must be supplied for a redox reaction to occur

c. always equal to Eanode - Ecathode

Explanation:

In an electrolytic cell; The electromotive force(the maximum standard potential difference) of the cell formed by the system is defined as the standard electrode potential of the right handed electrode minus the standard electrode potential of the left hand electrode. (i.e $\mathbf{E^{\theta}_{cell}=E_{anode} - E_{cathode}}$ )

As we all known that the process by which chemical energy is being converted to electrical energy is called the Electrochemical cell. It consists of two half cells , an oxidation half cell reaction and a reduction half-cell reaction.The overall redox reaction results in a flow of electrons in an electric current which is produced by a minimum voltage.

Therefore, option a and c are both correct.
