When a solution of ammonium sulfate is added to a solution of lead(II) nitrate, Pb(NO3)2, a white
precipitate, lead(II) sulfate, forms. Write a balanced
net ionic equation for this reaction. Both ammonium
sulfate and lead(II) nitrate, Pb(NO3)2 exist as
dissociated ions in aqueous solution.

What does a complete balanced chemical equation include? a. exothermic coefficients b. endothermic coefficients c. valence electrons d. molar coefficients

If 3 moles of a compound use 24 j of energy in a reaction, what is the a hreaction in j/mol?

Chlorine and water react to form hydrogen chloride and oxygen, like this: 2cl2 (g) + 2h2o (g) → 4hcl (g) + o2 (g) also, a chemist finds that at a certain temperature the equilibrium mixture of chlorine, water, hydrogen chloride, and oxygen has the following composition: compound concentration at equilibrium cl2 0.55m h2o 0.57m hcl 0.53m o2 0.34m calculate the value of the equilibrium constant kc for this reaction. round your answer to 2 significant digits.
