The standard molar entropy of lead(II) bromide (PbBr2) is 161 J/mol K. What is the entropy of 2.45 g of PbBr2? Show your work on the scratch sheet

You have been given an assertion statement and a reason. Select from A- D to locate the correct statement ? A) Both assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the assertion (A). B) Both Assertion (A) and reason (R) are true but Reason (R) is the not the correct explanation of the assertion (A). C) Assertion (A) is true, but Reason (R) is false. D) Assertion (A) is false, but Reason (R) is true. Assertion (A): At the triple point, the vapor pressure of the substance is equal for all three phases.Reason (R): The Clausius-Clapeyron equation can be used to describe pressure changes along all phase boundaries.

At 25°C, the vapor pressure of pure water is 25.756 mm Hg. What is the vapor pressure of water in a 0.500 m solution of sodium chloride? Show work, thought process on scratch paper

The enthalpy and entropy of vaporization of a liquid A are 38.6 kJ/mol and 109.8 J/mol · K, respectively. The boiling point of the liquid , in °C [blank1].  We know this because [blank2] Show your work on the scratch paper

You have two ligands, L1 and L2​, that bind to a metal ion M2+ with dissociation constants. Kd1=2.0×10−7 , Kd2=5.0 × 10−5. If a solution contains equimolar concentrations of L1​ and L2, which complex will predominate? Justify.

You have been given an assertion statement and a reason. Select from A- D to locate the correct statement ? A) Both assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the assertion (A). B) Both Assertion (A) and reason (R) are true but Reason (R) is the not the correct explanation of the assertion (A). C) Assertion (A) is true, but Reason (R) is false. D) Assertion (A) is false, but Reason (R) is true. Assertion (A): AgBr will precipitate before AgCl when a solution containing 0.050 M AgNO₃, 0.030 M NaCl, and 0.030 M NaBr is mixed. Reason (R): Ag⁺ ions have a stronger attraction to Br⁻ than to Cl⁻ because bromide is a larger anion.

In a lab simulation, students investigated the decomposition of hydrogen peroxide catalyzed by iodide ion 2H2O2(aq)       → 2(lH2O (l)     +      O2 (g)   They were given the following proposed reaction mechanism: Step 1: H2O2+I−→H2O+OI−\text{H}_2\text{O}_2 + \text{I}^- \rightarrow \text{H}_2\text{O} + \text{OI}^-  Step 2: H2O2+OI−→H2O+O2+I−\text{H}_2\text{O}_2 + \text{OI}^- \rightarrow \text{H}_2\text{O} + \text{O}_2 + \text{I}^- Student A made the following claim: “The iodide ion acts as a catalyst because it appears in the first step and disappears in the second.” Student B replied: “That can’t be right. The species that shows up in one step and is consumed in a later one without appearing in the overall reaction is actually the intermediate.” Based on their conversation, identify which species behaves as an intermediate in this mechanism.  Justify

A) Both assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the assertion (A). B) Both Assertion (A) and reason (R) are true but Reason (R) is the not the correct explanation of the assertion (A). C) Assertion (A) is true, but Reason (R) is false. D) Assertion (A) is false, but Reason (R) is true.   Assertion (A): If Q = K Q=K the forward reaction will proceed until all reactants are converted into products. Reason (R): At equilibrium, the rates of the forward and reverse reactions are equal.
