The product of the reaction between cyclohexene and hot acidified potassium manganate 7 will be cyclohexan-1,2-diol. Two hydroxy groups will bond at the site of the double bond.

acetone does not react with potassium dichromate
Here is the half equation for this reaction between sodium ethandioate and potassium manganate: 2MnO4- + 5C2O42- + 16H+ = 2Mn2+ + 10CO2 + 8H2O Carbon dioxide gas, water and sodium permanganate (a manganese (II) salt) is produced.
The half equation for the reduction of carbon dioxide to methanoic acid and its standard electrode potential value is given as: CO2 + 2H+ + 2e- gives HCOOH EO = -0.11 V The half equation for the reduction of ACIDIFIED potassium manganate(VII) and its standard electrode potential value is given as: MnO4- + 8H+ + 5e- gives Mn2+ + 4H2O EO = +1.51 V Thus, the standard electrode potential E for the overall reaction is: E = 1.51 - (-0.11) = +1.62 V Since it is positive (and well positive), the oxidation of methanoic acid by potassium manganate(VII) can take place under standard conditions. The overall equation (obtained by balancing the number of electrons) is: 2MnO4- + 6H+ + 5HCOOH gives 2Mn2+ + 8H2O + 5CO2
Well, if you look at the hazard symbols for potassium manganate and ethanol then you'd realise that potassium manganate is oxidising and ethanol is flammable therefore if you store them together then they can react very vigorously (if that's how you spell it) and maybe even cause a fire because the oxygen from the potassium manganate will give fuel to the fire ,maybe though. I'm not sure, it's something like that
There is no reaction, therefore no equation!!

ethanol is converted into acetic acid....
The reaction of cyclohexane with alkaline potassium permanganate is oxidation. This oxidation gives off the chemical cis-1,2-cyclohenanediol. The permanganate ion is reduced to green manganite.

KOH is the reactant in this reaction:2 MnO2 + 4 KOH + O2 = 2 K2MnO4 + 2 H2O

Mr. Yahya Maharmeh says that the oxidizing agents such as potassium dichromate are acidified to keep the solution acidic, so to provide hydrogen ions since the reaction needs alot of protons
toluene is benzene with CH3 reacting this with KMnO4 in acidic solution will produce a benzene with a carboxylic acid (CH3 will be oxidized)
"Reaction with what other substance? It needs something to react with." Yes, it depends with what it is reacting.....but permanganate is a oxidative reagent, so it could possible oxidate others reagents, like carbon double bonds or triple bonds....if it is acidic solution, it´s more oxidant....it can break bonds and oxidate organic compounds.....itI think that the question is what happens when potassium permanganate (manganate VII) is heated.potassium permanganate + heat= potassium oxide + oxygen
