A. H20+H30_H2O+Oh-
B. H2O+H2O_2OH-
C. H2O+H2O_2H3O
D. H2O+H2O_H3O+OH-

( _ meaning yield sign)

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.
