<span>In the process of electrolysis current can flow through a liquid because the liquid contents ions which are charged parciles (positive ions named cations, and negative ions named anions). Then, these charged particles are able to move freely through the liquid (just like electrons inside a solid conductor) which is electric current.</span>

Negative ions are attracted to the anode. In the process of electrolysis, current can flow through a liquid because negative ions are attracted to the anode.

Which metal is more active than NI and less active than Zn?

Mademuasel [1]

Answer : The correct option is, (2) Cr (Chromium)

Explanation :

The reactivity series of metal are arranged of the reactivity from the highest to the lowest. Reactivity series is used to determine the products of the single displacement reactions. In the single displacement reaction, the most reactive metal displaces the least reactive metal.

From the given reactivity series we conclude that there are two metal (Mg and Cr) are more reactive metal than the Ni and there are two metal (Pb and Cr) are less reactive metal than the Zn. So, the Cr (Chromium) is the metal which is more active than Ni and less active than Zn.

Hence, the correct option is, (2) Cr

Use your understanding of the ideal gas law to identify the correct relationships among the variables. Pressure is . Temperature

MAXImum [283]

Answer:

Pressure is inversely proportional to the volume of a gas at constant temperature and number of moles

Temperature is directly proportional to volume at constant pressure and number of moles

Volume is directly proportional to the number of moles of a gas at constant temperature and pressure

Explanation:

The ideal gas law is derived from a combination of the Boyle's, Charles' and Avogadro's law of gases.

Boyle's law states that at constant temperature, the volume of a given mass of gas (number of moles of gas is constant) is inversely proportional to the pressure exerted by the gas.

V ∝ 1/P (at constant n, T)

Charles'law states that at constant pressure, the volume of a given mass of gas (constant amount, n) is directly proportional to the temperature of the gas; V ∝ T (at constant n, P)

Avogadro’s law states that at constant temperature and pressure, the volume of a given mass of gas is directly proportional to the number of moles of gas present; V ∝ n(at constant T, P)

Combining the three equations gives the following relationship: V ∝ nT/P

By inserting a proportionality constant called the molar gas constant, R, in the relationship above, the ideal gas equation is derived as follows:

V = nRT/P or PV = nRT
