Consider the oxidation of gold metal in a mixture of nitric and hydrochloric acids (aqua regia) to produce AuCl4^-(aq) while nitrate ion is reduced to NO(g).
Use 1/2 reactions to write a balanced redox equation for this oxidation of gold metal in this acid mixture to produce NO(g). Is this reaction spontaneous under standard conditions?

Which of the following is correct regarding an acid-base conjugate pair. a. The conjugate base will have one less proton and one less negative charge. b. The conjugate acid will have one more proton and one less positive charge.
Further studies will refine how much water is needed for endangered species protection. States hope it will be the 130-150 KAF initially agreed upon rather than the 415 KAF the FWS thinks it is. What happen if cooperative agreement fails?
