Express your answer as part of a chemical equation. Identify all of the phases in your answer. Predict whether the equilibrium lies to the left or the right of the reaction arrow. H2CO3 (aq) + PO43- (aq) ⇌

You are on one of Saturn's many moons and discover a substance, Y2O that undergoes autoionization just like water on Earth.  Y2O + Y2O  ⇌ Y3O+ + OY– Through a series of experiments, you determine the equilibrium constant (Keq) for this autoionization reaction at various temperatures. The value of Keq at 28.7ºC is 7.6 x 10-14. What is the pY of the pure substance at this temperature? Report your answer to the hundreths place

When only one concentration at equilibrium is known the concentrations of the others can be calculated using stoichiometry. This is possible because all relationships in a chemical reaction are direct proportions. Calculate the the missing concentrations, then calculate the K, when a 0.050 M solution of CH3NH₂ is made, and at equilibrium [CH3NH₂] = 0.040 M.
