Thermochemical Equations Practice 1) Using the balanced thermochemical equation below: 2H2 + O2 + 2H20 + 241.8 kJ How much heat is released when 12.5 grams of hydrogen (Hz) are completely reacted?

N the field of chemistry, standard temperature and pressure conditions are:

How many grams of propane (C3H8) will react with 3.29 L of O2 at 1.05 atm and - 34° C? (Balance & use this equation: __ C3H8 + __ O2 → __CO2 + __ H2O)

Write the concentration equilibrium constant expression for this reaction. Cu (s) + 2Ag + (ag) - > Cu2 + (aq) + 2Ag (s)
