Each question has four options, and only one option is correct. You should choose the option that best answers the question.

To answer the questions, you should review the concepts and facts that you have learned in your chemistry class. You should also use your logical thinking and common sense to eliminate the wrong options. You can use a calculator, a periodic table, and a formula sheet to help you with the calculations and conversions.

Here is the answer key for part A of the practice test. For each question, we will show you the correct option and explain why it is correct. We will also show you why the other options are incorrect or irrelevant. You can use this answer key to check your answers and learn from your mistakes.

Question 1: Which of the following statements is true about chemical bonds

A) Chemical bonds are formed when atoms lose or gain electrons.

B) Chemical bonds are formed when atoms share electrons.

C) Chemical bonds are formed when atoms transfer protons.

D) Chemical bonds are formed when atoms exchange neutrons.

Answer: B) Chemical bonds are formed when atoms share electrons.

Explanation: Chemical bonds are the forces that hold atoms together in molecules or compounds. There are different types of chemical bonds, such as ionic bonds, covalent bonds, and metallic bonds. Ionic bonds are formed when atoms lose or gain electrons and become ions. Covalent bonds are formed when atoms share electrons and form molecules. Metallic bonds are formed when metal atoms share electrons and form a sea of electrons. Option B is correct because it describes covalent bonds, which are one of the types of chemical bonds. Option A is incorrect because it describes ionic bonds, not chemical bonds in general. Option C is incorrect because atoms do not transfer protons in chemical bonding. Option D is incorrect because atoms do not exchange neutrons in chemical bonding.

Question 2: What is the name of the molecular geometry of a molecule that has four bonded pairs and no lone pairs of electrons around the central atom

A) Tetrahedral

B) Trigonal planar

C) Linear

D) Bent

Answer: A) Tetrahedral

Explanation: Molecular geometry is the three-dimensional shape of a molecule that is determined by the arrangement of the bonded pairs and lone pairs of electrons around the central atom. To determine the molecular geometry of a molecule, we can use the VSEPR (valence shell electron pair repulsion) theory, which states that electron pairs repel each other and try to stay as far apart as possible. According to the VSEPR theory, a molecule that has four bonded pairs and no lone pairs of electrons around the central atom has a tetrahedral molecular geometry, which means that the four bonded pairs form a tetrahedron with angles of 109.5 degrees between them. Option A is correct because it names the tetrahedral molecular geometry. Option B is incorrect because trigonal planar molecular geometry has three bonded pairs and no lone pairs around the central atom. Option C is incorrect because linear molecular geometry has two bonded pairs and no lone pairs around the central atom. Option D is incorrect because bent molecular geometry has two bonded pairs and one or two lone pairs around the central atom. a474f39169
