The volume of neon gas should be determined. Concept Introduction: The volume of neon gas in this case can be determined using Boyle’s law. Boyle’s law is an experimental gas law states that pressure has inverse relation with volume and it is expressed as: P ∝ 1 V o r , PV=constant Where, P is the pressure of the gas And V is the V is the volume of the gas The law states that the multiplication of pressure and volume is constant for a given mass of gas at constant temperature. Now, for two dissimilar conditions sets for comparison of same substance, the law can be usefully expressed as: P 1 V 1 = P 2 V 2 .

Question

a) A favorable entropy change occurs when ΔS is positive. Does the order of the system increase or decrease when ΔS is positive? (b) A favorable enthalpy change occurs when ΔH is negative. Does the system absorb heat or give off heat when ΔH is negative? (c) Write the relation between ΔG, ΔH, and ΔS. Use the results of parts (a) and (b) to state whether ΔG must be positive or negative for a spontaneous change. For the reaction, ΔG is 59.0 kJ/mol at 298.15 K. Find the value of K for the reaction.

Question

Chapter 13.2, Problem 13.2SC

Interpretation Introduction

Interpretation:

The volume of neon gas should be determined.

Concept Introduction:

The volume of neon gas in this case can be determined using Boyle’s law.

Boyle’s law is an experimental gas law states that pressure has inverse relation with volume and it is expressed as:

P∝1Vor, PV=constant

Where, P is the pressure of the gas

And V is the V is the volume of the gas

The law states that the multiplication of pressure and volume is constant for a given mass of gas at constant temperature. Now, for two dissimilar conditions sets for comparison of same substance, the law can be usefully expressed as:

P1V1=P2V2.

A sample of hydrated magnesium sulfate (MgSO4⋅xH2O) is analyzed using thermogravimetric analysis (TGA). The sample weighs 2.50 g initially and is heated in a controlled atmosphere. As the temperature increases, the water of hydration is released in two stages: (a) The first mass loss of 0.72 g occurs at 150°C, corresponding to the loss of a certain number of water molecules. (b) The second mass loss of 0.90 g occurs at 250°C, corresponding to the loss of the remaining water molecules. The residue is identified as anhydrous magnesium sulfate (MgSO4) Questions: (i) Determine the value of x (the total number of water molecules in MgSO4⋅xH2O) (ii) Calculate the percentage of water in the original sample. Write down the applications of TGA.

The solubility product of iron(III) hydroxide (Fe(OH)3) is 6.3×10−38. If 50 mL of a 0.001 M FeCl3 solution is mixed with 50 mL of a 0.005 M NaOH solution, will Fe(OH)3 precipitate? Show all step-by-step calculations. To evaluate the equilibrium constant, we must express concentrations of solutes in mol/L, gases in bars, and omit solids, liquids, and solvents. Explain why.
