How do you produce hydrogen biologically

• By steam reformer process

• Action of microorganisms and sunlight turns water and organic matter into oxygen and hydrogen ions. Hydrogen ions produced is released as hydrogen gas

Which of the following reaction represents Metal oxide + hydrogen gas

• ZnO + H2 ----> Zn + H2O

• NaH + H2O ------> NaOH + H2

H2 + Br2 ---->

• 2HCl

• 2HBr
