(CH3-CH3) y (CH3- CH2- CH3) son isomeros Sí o No porqué?

the answer is either b or c

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 think its 5049.

i hope this !

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
