What is heat of reaction​

If the atomic mass of an atom is 34 and the atom contains 13 protons, how many neutrons does the atom contain?

If 22.5 liters of oxygen reacted with excess of hydrogen, how many liters of water vapor could be produced?

Consider the following reaction at equilibrium: c(s)+h2o(g)⇌co(g)+h2(g) predict whether the reaction will shift left, shift right, or remain unchanged upon each of the following disturbances. a) c is added to the reaction mixture. b) h2ois condensed and removed from the reaction mixture c) co is added to the reaction mixture d) h2 is removed from the reaction mixture.
