For the reaction system 2H2(g) + S2(g) 2H2S(g), a 1.00 liter vessel is found to contain 0.5 moles of H2 0.02 moles of S2, and 68.5 moles of H2S. What is the mass action expression? Use the format (H2S = Hs2S)

Would greatly appreciate seeing the full process and all calculations. Thank you!

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.

what is the question here. i think you messed up.

i dont know the answe
