How many sulfur atoms are in a metric ton (1.00 x 10^6g) of sulfur

use dimensional analysis

1.00 e6 g S  x  (1 mole S / 32.1 g S)  x  (6.02 e23 atoms S / 1 mole S) = 1.88 e30 atoms S

Explanation:

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.
