What are the reducing agents and oxidizing agents? Is potassium permangate a reducing or oxidizing agent???

Does anybody hav a note on chemistry on what we should memorize on...the memorizing things for the exams?..this will be very useful to me and others coz I don't wana memorize the whole book :p

KMnO4 is a strong oxidizing agent
An oxidizing agent (also called an oxidizer ) can be defined as a substance that removes electrons from another reactant in a redox chemical reaction. The oxidizing agent is "reduced" by taking electrons onto itself and the reactant is "oxidized" by having its electrons taken away.
a reducing agent (also called a reductant or reducer) is the element or compound in a reduction-oxidation (redox) reaction that donates an electron to another species; however, since the reducer loses an electron we say it is "oxidized". This means that there must be an "oxidizer"; because if any chemical is an electron donor (reducer), another must be an electron recipient (oxidizer). Thus reducers are "oxidized" and oxidizers are "reduced".

well let me share with you a tip

KMnO4
K2Cr2O7 both are OXIDISING AGENTS...now whats common here...lets see..oh....they both have alot of O atoms....so i used the trick to remember that these two have great amount of O atoms so they just give them away and Reduce themselves and oxidise the other...:D
same is with KI, has no O atoms so its a reducing agent...

beacuse see W=mg
m increases w increases
W=F
F=ma
so F increases a increases
no?

sure , but you skipped the part that you asked:

F/m = a

so when m increases a decreases .
Mass is proportional to accelaration (if Force remains constant ) but is certainly not dependent on it .
Dependence would mean that a specific mass produces only a specific accelaration. Which is totally wrong.

So the answer to your question is : No
