Is this reaction oxidation or reduction
CH2=CH2 + OsO4 yields to HOCH2CH2OH

it's definitely a oxidation reaction because here the oxygen contained OH group present in yeild

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

i believe it is a.) released into
