A Brief History Of The AP Chemistry Exam*
Assuming no volume change, does [CrO 2 4 ] increase, decrease, or remain the same? The [CrO 4 2 ] will decrease. To re-establish equilibrium, the reaction goes rom right to let, decreasing the quotient to return to equilibrium. The equilibriumconstant expression or the dissolving o Ag 3 PO 4 s in water is shown below. Support your answer with calculations. H is the more important actor. The reaction is exothermic, which avors spontaneity. S is negative, which means the system becomes more ordered as the reaction proceeds. Greater order will not increase the spontaneity o the reaction. The reaction represented below also produces iron iii oxide. The value o per mole o Fe 2 O 3 s ormed. H or the reaction is Species X has a molar absorptivity constant o cm 1 M 1 and the path length o the cuvette containing the reaction mixture is 1.

The same logic can be used to identiy solution Y. I no precipitate orms, solution X must be AgNO 3. A strip o Sn and a strip o an unknown metal, X, are used as electrodes. When the switch is closed, the mass o the Sn electrode increases. The hal-reactions are shown below. The Sn tin electrode is the cathode.

Cr 1 point or correct metal e Write a balanced net-ionic equation or the overall chemical reaction occurring in the cell. E cell, be greater than, less than, E cell will be greater more positive. Since the Q ratio is a number less than 1, the log o the ratio will be negative. A negative times a negative is positive. Thus, [0. In each part, your response must include speciic inormation about both substances. Both F 2 and I 2 are nonpolar, so the only intermolecular attractive orces are London dispersion orces. I 2 is solid because the electrons in the I 2 molecule occupy a larger volume and are more polarizable compared to the electrons in the F 2 molecule.

As a result, the dispersion orces are considerably stronger in I 2 compared to F 2. Both NaF and CsCl are ionic compounds with the same charges on the cations and anions. John A. Melting occurs when the attraction between the cation and the anion are overcome due to thermal motion. Since the lattice energy is inversely proportional to the distance between the ion centers Coulomb s Law , the compound with the smaller ions will have the stronger attractions and the higher melting point. The central iodine atom in ICl 4 has our bonding pairs and two lone pairs o electrons on the central iodine atom, so the molecular geometry is square planar. BF 4 has our bonding pairs and no lone pairs on the central boron atom, so the molecular geometry is tetrahedral.
