The pressure of a gas is reduced from 1200.0 mmhg to 850.0 mmhg as the temperature of its container is increased from 90.0 c to 785.75 c. what would be the final volume be if the original volume was 85.0 ml ?

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.

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )
