Chapter 5, Problem 1Q

In any language, water is the most abundant compound on the surface of the Earth.

  1. a. Explain the term compound and also why water is not an element.
  2. b. Draw the Lewis structure for water and explain why its shape is bent.

(a)

Expert Solution

Interpretation Introduction

Interpretation:

The reason for water is not an element has to be explained.  Also, the term compound has to be explained.

Explanation of Solution

  • Water is a compound not an element because it has two hydrogens and one oxygen and the chemical formula is H2O.
  • Compound: It is a pure substance in which two or more different elements are combined in a fixed ratio with specific chemical characteristics.

(b)

Interpretation Introduction

Interpretation:

The Lewis structure of water has to be drawn.  Also, the reason for bent shape of water has to be explained.

Concept Introduction:

Lewis structure: This is only way to show the sharing of electrons between atom in polar covalent bonds or covalent bond.  This is often called Lewis structure.  This structure denotes valence electrons of an atom by dots and also it shows the way of valence electron distributed within a molecule.

Explanation of Solution

The Lewis structure for water is drawn as,

Chemistry in Context, Chapter 5, Problem 1Q

Two nonbonding lone pairs of electrons on oxygen atom gives extra repulsion on two bond pair electrons between hydrogen and oxygen which makes water molecule to be in bent shape.  The bent shape allows electrons in water molecule to be placed without any congestion.

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.
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.
