Oxygen in the air can cause sliced fruit to brown, a process called enzymic browning (an oxidation reaction). Phenols and the enzyme phenolase are found in the cells of the apple, and when these are exposed to oxygen in the air, for example through slicing, the oxygen causes a reaction.
Does a rotten apple taste different from a fresh apple?

I think that indeed it does!! handsome bulldoggie! I think that indeed it does!! handsome bulldoggie!
O = -2 oxidation state H = +1 oxidation state
Hydrogen's oxidation number is +1.Chlorin's oxidation number is +1.Oxygen's oxidation number is -2.
S = +4 oxidation state O = -2 oxidation state
K = +1 oxidation state Cl = +3 oxidation state O = -2 oxidation state
yes
You expose the flesh of the fruit to oxidation. Also, if you do this in a store (yikes!) you ruin the fruit; you make it unsuitable for someone else to buy. That is stealing, unless you buy the fruit regardless of what you find.
Open due to oxidation and potential for insects and other things to get in.
Oxidation is cause by (obviously) the oxygen in the air. When you cut up fruit for instance, the parts without skin which are exposed will turn brown quickly. Squeezing lemon juice over your fruit (apple, pear, banana, ect) will stop oxidation because the juice contains Vitamin C (ascorbic acid). The ascorbic acid reacts with the oxygen preventing the browning on the apple (fruit). In theory, other citric fruits would do the same thing. Whenever making an apple pie (or pear whatever) squeeze a lemon over the pieces as you cut them up (and toss) this will stop the oxidation process while you are cutting up all the fruit.

Petroleum Jelly on the cut edges of a pumpkin will slow the oxidation and rotting of the fruit.

Co = +2 oxidation C = +4 oxidation O = -2 oxidation
When fruit flesh is exposed to air, it experiences oxidation, much like iron does. This reaction doesn't result in the rust that iron's reaction does, but it is responsible for the brown coloring that this exposed fruit flesh takes on.
Oxidation is defined as the interaction between oxygen molecules and all the different substances they may contact, from metal to living tissue. Technically, however, with the discovery of electrons, oxidation came to be more precisely defined as the loss of at least one electron when two or more substances interact. Those substances may or may not include oxygen. (Incidentally, the opposite of oxidation is reduction - the addition of at least one electron when substances come into contact with each other.) Sometimes oxidation is not such a bad thing, as in the formation of super-durable anodized aluminum. Other times, oxidation can be destructive, such as the rusting of an automobile or the spoiling of fresh fruit.
O = -2 oxidation state H = +1 oxidation state
Oxidation number is oxidation states of an element. It can be positive or negative.
