2.  The liver enzymes reacted with the hydrogen peroxide, and created oxygen and water.
3.  The red hot wood sets on fire. This happens because the oxygen created by the reaction causes the wood to create sparks and catch on fire.
4. When the liver was boiled, the enzymes deactivated, and no reaction occurred. ]]> 2017-02-13 15:31:47 UTC https://padlet.com/8564942/v4o9hnzoszhv/wish/153455744 8564942 https://padlet.com/8564942/v4o9hnzoszhv/wish/153459286 After observing this experiment, I can conclude that my hypothesis was correct, the liver did react with the peroxide to create water and oxygen, but when the liver was boiled, there was no reaction. The liver in tube three reacted with the H2O2 to create water and oxygen. we know this because when we stuck a red hot wooden rod in it, it created a flame, which only oxygen can provoke. Hydrogen peroxide does not do this by itself. Also, when the liver was boiled before it was put in the peroxide, it didn't make a reaction because the enzymes in the liver were deactivated. I learned that enzymes provoke reactions that normally are slow or don't happen at all. I also learned that these reactions can stop if the liver is heated to the point where the enzymes deactivate. ]]> 2017-02-13 15:40:08 UTC https://padlet.com/8564942/v4o9hnzoszhv/wish/153459286
