Electrolysis is a process that .A. produces an electrical current while decomposing water into hydrogen gas and oxygen gas. B. requires an electrical current to decompose water into hydrogen gas and oxygen gas. C. produces heat energy while decomposing water into hydrogen gas and oxygen gas. D. requires heat energy to decompose water into hydrogen gas and oxygen gas.

B. requires an electrical current to decompose water into hydrogen gas and oxygen gas

Explanation:

Electrolysis is a process that requires electric current to split water into hydrogen gas and oxygen gas. This electrolysis is a process whereby electric current is use to effect a chemical change.

Components that are required for electrolysis are electrodes, electrolytes and direct currents.  

The direct current produces the energy for the ions to discharge or create the ions in the electrolytes.

The electrodes is the conductor that provides the interface in which current enters and goes out of the electrolyte.  Anode is where the current enters the electrolytes. The cathode is where the current lives the electrolytes.  

The electrolytes contains free ions and produce an electrically conducting solution in polar solvent.
