This is to prove that the liver will break down peroxide to water and oxygen

Peroxide is said to be very dangerous and poisonous,

doing this lab will prove that the liver will break down

the second tube we will put peroxide and a piece of liver

the third tube to fill it up with peroxide

light a wooden splint on fire and let it burn for a while

fill up the fourth test tube with peroxide and add the liver

again light up the wooden splint and let it burn &

put it up to the fourth tube

the fifth tube has been boiled

peroxide, water and boiled water is to be put in the fifth

tube

Their roles in chemical reactions are to increase the rate of

reaction

WHY is the flame being produced?  i_amawesome2010 https://padlet.com/i_amawesome2010/k4wlyralqmpa/wish/50104316 The red hot wood actually makes it turn into fire because when pure oxygen Is in presense of a spark will cause a fire
