What is the change in enthalpy when 250 g of water vapor condenses at 100oc? (δhv = 40.67 kj/mol)

-564.4996 kJ is the change in enthalpy when 250 g of water vapor condenses at 100°C.

Explanation:

Moles of water =

Heat of condensation of 1 mol of water =

Heat change when 250 grams of water condenses at 100° C:

-564.4996 kJ is the change in enthalpy when 250 g of water vapor condenses at 100°C.

answer: find it ur self

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.
