Wanda learned that deuterium (H-2); an isotope of hydrogen, has one proton and one neutron, and
that protium (H-1) has one proton and no neutrons.
She concluded that deuterium and protium are two
different elements.

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.
