Final answer:
To build a molecule with two carbon and six hydrogen atoms, drag atoms from the appropriate atom's "Kit" in the Build a Molecule simulation. The correct step is to drag atoms above the Kit, creating ethane (C2H6). Different arrangements or additional atoms can lead to other compounds like ethylene (C2H4) or ethanol (C2H5OH).
Step-by-step explanation:
To build a molecule with two carbon atoms and six hydrogen atoms in the Build a Molecule simulation, you should select the appropriate atom's "Kit" that contains carbon and hydrogen atoms. You would then drag these atoms into the space above the "Kit" to assemble your molecule.
The bond formation is intuitive: each carbon atom can form four bonds and each hydrogen atom can form one bond, allowing you to arrange them in a standard alkane configuration. Upon arranging two carbon atoms and six hydrogen atoms correctly, you would form ethane, which has a condensed structural formula of C2H6.
This can be visualized as two carbon atoms in the center, each bonded to three hydrogen atoms. In a different arrangement, you might create ethylene (C2H4) if fewer hydrogen atoms are used, or an entirely different molecule if additional elements like oxygen are included as in the case of ethanol (C2H5OH) for example.
Therefore, the correct answer to the question would be: b) Drag atoms into the space above the Kit. The structural formula of this molecule is H3C-CH3, and its name is ethane. You can indeed arrange these atoms to make a different compound such as ethylene or ethanol if oxygen atoms are available.
