What's happening
Question | Answer |
---|---|
What happens to the hydrogen molecules when we remove the battery? | the hydrogen molecules that are clinging as bubbles to the electrode, break up |
What happens after hydrogen molecules break up? | they form into positively charged hydrogen ions and electrons |
What happens to the oxygen molecules after we remove the water? | the oxygen molecules draw electrons from the metal, and then combine with the hydrogen ions to form water |
How many electrons does the oxygen electrode losses? | lost 2 electrons to each oxygen molecule |
How many electrons does the hydrogen electrode gain? | gained 2 electrons from each hydrogen molecule? |
Is the electrons at the hydrogen electrode attracted to the positively charged oxygen electrode after the lossing and gaining electrons? | yes |
