Correct Answer: C) deposition and evolution

Explanation

In the electrolysis of copper (II) sulphate using copper electrodes, we have two processes occurring at the anode and cathode. Let's examine each process separately.

Anode: The anode is the positive electrode where oxidation occurs. During the electrolysis of copper (II) sulphate, copper atoms from the anode lose two electrons and go into the solution as copper ions (Cu²⁺). This process is called dissolution. The half-equation for this process is:

\(Cu(s) \rightarrow Cu^{2+}(aq) + 2e^-\)

Cathode: The cathode is the negative electrode where reduction occurs. Copper ions (Cu²⁺) from the solution gain two electrons and get deposited on the cathode as copper atoms. This process is called deposition. The half-equation for this process is:

So, during the electrolysis of copper (II) sulphate using copper electrodes, the processes that occur at the anode and cathode respectively are dissolution and deposition, which corresponds toOption C.

Explanation

The rights of the individual can be restricted under the following circumstances:

(i)Imprisonment: if an individual is convicted by a court of law and imprisoned, his rights can be restricted.

(ii)State of emergency: If there is a state of emergency in a country, e.g natural disasters like flood, earth quake or during war time, restriction of individual rights may result.

(iii)Epidemic: There may be restriction also if there is an outbreak of epidemic in the society, e.g small-pox, cholera, yellow fever, etc.

(iv)Remanded in the custody: The determination of the cases of an individual may be pending and the court may order him to be remanded in custody. This is a restriction on his rights.

(v)Arrest of the individual: If an individual is arrested by the law enforcement agents and is awaiting appearance in court, such is a restriction on his rights.

(vi)National security:An individual may be detained in the interest of national security.

(vii)Unsound mind: some people of unsound mind may be detained or incarcerated.

(viii)Type of government:The provisions of the constitution are not respected and adhered to by any of the Military or one party system.

(ix)Death sentence:The conviction of an individual may result in his facing firing squad or by hanging.

(x)Children: Children in need of care and protection may be detained and this is a restriction on their rights
