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 data rom the experiment are given in the table below. Include units with your answer. Data rom these experiments were used to produce the graph below, where T is temperature.
- The vertical axis should be labeled ln k. Answers to more than ive choices will not be graded. In all cases, a reaction occurs. Assume that solutions are aqueous unless otherwise indicated. Represent substances in solution as ions i the substances are extensively ionized. Omit ormulas or any ions or molecules that are unchanged by the reaction. You need not balance the equations. Example: A strip o magnesium is added to a solution o silver nitrate. Excess concentrated aqueous ammonia is added to a solution o nickel ii bromide. The student is also given two lasks that are labeled X and Y. One o these lasks contains 1. This inormation is summarized in the diagram below.
- A precipitate also ormed when samples o solutions Q and Y were combined. Solution Q is K 2 CO 3 1 point or correct identiication o solution Q ii Write the chemical ormulas or each o the two precipitates. Search Results However, no precipitate orms when solution Q is mixed with solution S. PbCO 3 1 point or correct ormula o the precipitate Visit apcentral. The identities o solutions X and Y can be determined by adding a sample o NaCl to each solution. NaCl will orm a white precipitate when added to a solution o AgNO 3, but will not orm a precipitate when added to a solution o BaCl 2. 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. Diagram should have arrow showing electrons lowing rom the anode towards 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. Ap Microeconomics Frq Visit apcentral. Water also has hydrogen-bonding intermolecular attractive orces. Ammonia is more soluble in water than phosphine because ammonia molecules can hydrogen-bond with water molecules, whereas phosphine molecules cannot hydrogen-bond with water molecules. Assume that both gases exhibit ideal behavior. CO 2 has a linear molecular geometry 1 point or correct molecular geometry c One o the two gases dissolves readily in water to orm a solution with a ph below 7.
- Identiy the gas and account or this observation by writing a chemical equation. On the graph below, sketch the expected plot o volume versus temperature as the gas is heated.
