what explosive/accelerant gases do automotive 12 volt lead - acid batteries release?
○ nitrogen and hydrogen
○ hydrogen and oxygen
○ carbon and oxygen
○ nitrogen and oxygen

Explanation:

Automotive 12 - volt lead - acid batteries undergo electrolysis of water during charging. The chemical formula for water is \(H_2O\). During electrolysis, water decomposes into hydrogen (\(H_2\)) and oxygen (\(O_2\)) gases. Nitrogen (\(N_2\)) and carbon (\(C\)) are not involved in the normal electrochemical reactions of lead - acid batteries that produce explosive/accelerant gases.

Answer:

Hydrogen and oxygen.
