carbon dioxide gas diffuses through a porous barrier at a rate of 0.20 ml/minute. if an unknown gas diffuses through the same barrier at a rate of 0.313 ml/minute, what is the molar mass of the unknown gas?

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.

it is the most commonly accepted one

answersilicon (si); oxygen (o);
