B. 20. g/mol
C. 32 g/mol
D. 64 g/mol

C6H24S3

Explanation:

D.64 g/mol hope this help

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.
