If I have 8.5 L of gas in a piston at a pressure of 2.5 atm and compress the gas until its volume is 6.5 L. What will the new pressure inside the piston be?

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.

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.
