It's observation and a hypothesis.
<span>Hydrogen fusion generates the energy for proton - proton chains and the carbon nitrogen oxygen cycle. It is the nuclear fusion of 4 protons to form a helium 4 nucleus.</span>
Answer : The correct option is, (3) Oxidation occurs at the anode and reduction occurs at the cathode.
Explanation :
Electrochemical cell : It is a type of device which is used to convert the chemical energy into electrical energy during the redox reaction.
In the electrochemical cell, there are two electrodes. The electrode on which the oxidation takes place is called the anode (or negative pole) and the electrode on which the reduction takes place is called the cathode (or positive pole). This cell is connected by the salt bridge.
In the external circuit, the electrons flow from the anode (negative pole) to cathode (positive pole) through the voltmeter.
In the inner circuit, the ions flow through the salt bridge.
Hence, the correct option is, (3) Oxidation occurs at the anode and reduction occurs at the cathode.
