Solution Steps

Step 1: Understanding Lewis Structures

Lewis structures are diagrams that represent the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule. They are essential for understanding the arrangement of electrons in a molecule.

Step 2: Identifying the First Step

The first step in creating a Lewis structure is to determine the total number of valence electrons available for bonding. This is crucial because it sets the foundation for how the atoms will be arranged and how the electrons will be distributed in the molecule.

Step 3: Counting Valence Electrons

To count the number of valence electrons, you need to consider the group number of each atom in the periodic table. The group number often corresponds to the number of valence electrons for main-group elements.

Final Answer

The first step in creating a Lewis structure for a molecule is: \(\boxed{\text{D. counting the number of valence electrons}}\)

Solving for a gaseous reactant 3 / 5 Kassi The great French chemist Antoine Lavoisier discovered the Law of Conservation of Mass in part by doing a famous experiment in 1775. In this experiment Lavoisier found that mercury(II) oxide, when heated, decomposed into liquid mercury and an invisible and previously unknown substance: oxygen gas. 1. Write a balanced chemical equation, including physical state symbols, for the decomposition of solid mercury(II) oxide ( HgO ) into liquid mercury and gaseous dioxygen. 2. Suppose 23.0 mL of dioxygen gas are produced by this reaction, at a temperature of 130.0°C and pressure of exactly 1 atm. Calculate the mass of mercury(II) oxide that must have reacted. Round your answer to 3 significant digits. g
