Which of the following figures represents (c) a pure compound, (More than one picture might fit each description.)

Verified step by step guidance

1. Understand the definition of a pure compound: A pure compound consists of two or more elements chemically combined in a fixed ratio, and it has distinct chemical properties.
2. Identify the characteristics of a pure compound in diagrams: Look for a consistent pattern of two or more different types of atoms bonded together throughout the figure.
3. Examine each figure provided: Check if the figure shows a consistent and repeating pattern of bonded atoms, indicating a pure compound.
4. Compare the figures: Determine which figures show only one type of molecule throughout, as this indicates a pure compound.
5. Select the figures that match the criteria: Choose the figures that consistently show the same type of molecule, representing a pure compound.

Key Concepts

Pure Compound

A pure compound consists of two or more elements that are chemically bonded in a fixed ratio. Unlike mixtures, pure compounds have uniform properties throughout and can be represented by a specific chemical formula, such as H2O for water or NaCl for table salt. Understanding the distinction between pure compounds and mixtures is essential for identifying them in visual representations.

Chemical Bonding

Chemical bonding refers to the forces that hold atoms together in a compound. The two primary types of bonds are ionic bonds, formed through the transfer of electrons, and covalent bonds, formed through the sharing of electrons. Recognizing the type of bonding can help in identifying the nature of the compound and its properties, which is crucial when analyzing figures representing compounds.

Visual Representation of Compounds

Visual representations of compounds can include molecular structures, chemical formulas, or diagrams that illustrate the arrangement of atoms. These representations help convey information about the composition and structure of the compound. Being able to interpret these visuals is key to determining whether a figure accurately depicts a pure compound or a mixture.
