Abeam of radiation has an energy of 2.39×10^2 kj/mol. what is the wavelength of this light?

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.

answersilicon (si); oxygen (o);
