Which of the following has a molar mass of 198.1 g/mole? Refer to the periodic table. *
C4H12NO,
C6H140-
C12H22011
C6H12O6

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.

answer///carbon;
