A teacher cut an apple into three wedges of the same size. she dipped one wedge in the lemon juice ,dipped another in water and left one alone. then she left the wedges on a paper towel in her desk. after 1 hour only the wedge that had been dipped in lemon juice was still yellow .the other two wedges had turned brown. what is one way the teacher could replicate this experiment?

i think the answer is terrae but not 100 percent sure. ▓▬▬ §

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )

since electrons are negative the answer is neagtaive
