which statement correctly explains why a fuel cell is a voltaic cell?\nit is composed of one oxidation half - reaction.\nit is composed of one reduction half - reaction.\nit transfers electrons from oxidation reactions to reduction.\nit requires either an anode or a cathode but not both.
Answer
# Brief Explanations:
A voltaic cell involves redox reactions. Oxidation (loss of electrons) occurs at the anode and reduction (gain of electrons) occurs at the cathode. In a fuel cell (a type of voltaic cell), electrons are transferred from the oxidation half - reaction to the reduction half - reaction. A voltaic cell cannot be composed of just one half - reaction (oxidation or reduction alone, so the first two options are wrong). Also, a voltaic cell requires both an anode (where oxidation occurs) and a cathode (where reduction occurs), so the fourth option is wrong.
# Answer:
It transfers electrons from oxidation reactions to reduction.
