4. Identify the acid, base, conjugate acid and conjugate base for each of the following. ( 3pts each)
a. HClO4(aq) + H2O(1) H3O*(aq) + ClO4 (aq)
b. H2SO3(aq) + H2O(1) H3O+(aq) + HSO3(aq)
C. HC2H2O2(aq) + H2O(1) = H3O+(aq) + C2H302 (aq)
d. H S(g) + H2O(l) = H3O+ (aq) + HS-(aq)

Ammonia and oxygen react to form nitrogen monoxide and water, like this: 4nh3 (g) + 5o2 (g) → 4no (g) + 6h2o (g) also, a chemist finds that at a certain temperature the equilibrium mixture of ammonia, oxygen, nitrogen monoxide, and water has the following composition: compound pressure at equilibrium nh3 65.1atm o2 31.3atm no 62.7atm h2o 65.8atm compound pressure at equilibrium nh3 65.3 atm o2 7.79 atm no 12.1 atm h2o 65.8 atm calculate the value of the equilibrium constant kp for this reaction. round your answer to 2 significant

Freezing and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.

Many pharmaceutical drugs are organic compounds that were originally synthesized in the laboratory. which two scientific disciplines are bridged by pharmaceutical drugs? chemistry and forensics chemistry and medicine biology and forensics biology and criminology
