Open the Build a Molecule simulation (http://openstaxcollege.org/l/16molbuilding) and select the “Larger Molecules” tab. Select an appropriate atoms “Kit” to build a molecule with two carbon and six hydrogen atoms. Drag atoms into the space above the “Kit” to make a molecule. A name will appear when you have made an actual molecule that exists (even if it is not the one you want). You can use the scissors tool to separate atoms if you would like to change the connections. Click on “3D” to see the molecule, and look at both the space-filling and ball and-stick possibilities.(a) Draw the structural formula of this molecule and state its name.(b) Can you arrange these atoms in any way to make a different compound?

Short Answer

Expert verified

a. The molecule’s name is Ethane and the structure is:

b. No, we cannot arrange two carbon and six hydrogen atoms in another way to make a different compound.

Step by step solution

01

Draw the structural formula of molecules and state its name.

The3D structureof the molecule is drawn below:

The name of the structure is Ethane.

02

Determine whether we can arrange these atoms in any way to form a different compound.

The only possible structure formed by the two carbon atoms and six hydrogen atoms is Ethane. So, we cannot arrange these atoms in a way to form a different compound.

Open theBuild an Atom simulation (http://openstaxcollege.org/l/16PhetAtomBld)and click on the

Atom icon.

a. Pick any one of the first 10 elements that you would like to build and state its symbol.

b. Drag protons, neutrons, and electrons onto the atom template to make an atom of your element.

State the numbers of protons, neutrons, and electrons in your atom, as well as the net charge and mass number.

c. Click on “Net Charge” and “Mass Number,” check your answers to (b), and correct, if needed.

d. Predict whether your atom will be stable or unstable. State your reasoning.

e. Check the “Stable/Unstable” box. Was your answer to (d) correct? If not, first predict what you can do to make a Stable atom of your element, and then do it and see if it works. Explain your reasoning.
