What is the total internal translational (kinetic) energy of the Cl2 molecules in a 11.2 liter bulb at 0oC and 8 atm

How much heat is released upon converting one mole of steam (18.0 g) from 100.0 ∘c to water at 25.0 ∘c? show work and constants, trying to figure out how it works. only given the heat capacity for steam and water so try to only use that

What are the spectator ions in 2h+ + so42- + ca2+ + 2r → caso4 + 2h+ + 21?

When a spring is compressed, the energy changes from kinetic to potential. which best describes what is causing this change?
