69. Explain why the atoms in the CH 4 molecule are arranged with a tetrahedral molecular shape. 70. Compare and contrast the information given in the Lewis structure, the space‑filling model, the ball‑and‑stick model, and the geometric sketch of a methane molecule, CH 4 . 71. Compare and contrast the information given in the Lewis structure, the space‑filling model, the ball‑and‑stick model, and the geometric sketch of an ammonia molecule, NH 3 . 72. Compare and contrast the information given in the Lewis structure, the space‑filling model, the ball‑and‑stick model, and the geometric sketch of a water molecule, H 2 O. 73. What are the particles that form the basic structure of water? Describe the attraction that holds these particles together. Draw a rough sketch that shows the attraction between two water molecules. 74. Describe the structure of liquid water. Section 3.4 Naming Binary Covalent Compounds 75. What is wrong with using the name nitrogen oxide for NO? Why can’t you be sure of the formula that corresponds to the name phosphorus chloride ? 76. The compound represented by the ball‑and‑stick model to the left is used in the processing of nuclear fuels. Although bromine atoms most commonly form one covalent bond, they can form five bonds, as in the molecule shown here, in which the central sphere represents a bromine atom. The other atoms are fluorine atoms. Write this compound’s chemical formula and name. List the bromine atom first in the chemical formula. 77. The compound represented by the ball‑and‑stick model to the left is used to add chlorine atoms to other molecules. Write its chemical formula and name. The central ball represents an oxygen atom, and the other atoms are chlorine atoms. List the chlorine atom first in the chemical formula. 78. The compound represented by the space‑filling model to the left is used to vulcanize rubber and harden softwoods. Write its chemical formula and name. The central ball represents a sulfur atom, and the other atoms are chlorine atoms. List the sulfur atom first in the chemical formula. 79. The compound represented by the space‑filling model to the left is used in processing nuclear fuels. The central sphere represents a chlorine atom, which in most cases would form one covalent bond but is sometimes able to form three bonds. The other atoms are fluorine atoms. Write this compound’s chemical formula and name. List the chlorine atom first in the chemical formula. 80. Write the name for each of the following chemical formulas.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
