select the correct answer.\nwhat does this chemical reaction describe?\nwater → hydrogen + oxygen\na. respiration\nb. decomposition of water\nc. combustion of hydrogen fuel\nd. chemical reaction in a battery

Answer

Brief Explanations:

  • Respiration involves glucose and oxygen reacting to produce carbon dioxide, water, and energy.
  • Decomposition of water means water breaks down into hydrogen and oxygen, which matches the given reaction.
  • Combustion of hydrogen fuel is hydrogen reacting with oxygen to form water.
  • Chemical reaction in a battery is a different set of redox reactions depending on the battery type.

Answer:

B. decomposition of water
