Answer the following questions. You may use the periodic table in the Chemistry: Problems and Solutions book for this test. When you have finished, submit this assignment to your teacher by the due date for full credit. (5 points) Score 1. Pentane gas (C5H12) combusts with oxygen gas (O2) to form water (H2O) and carbon dioxide (CO2). Write a balanced chemical equation for this reaction and explain the scientific principle (statement) that requires the balancing of an equation to make it conform…

vertical columns. Each column is called a group. The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements. Every element in…

figuring out the shape of the orbitals and where to put the orbitals. As my teacher recommended, I first sketched out a diagram of my model using the information I knew. The main component of the quantum model is knowing the quantum numbers of the electrons in the last orbitals and how they apply to the orbitals. After figuring the quantum numbers, I was able to figure out the shape of the orbitals and where to build each one using the x, y, and z axis. After finalizing the sketch of my model, I…

conformation according to the information that was given by chemical physicists. The physicist he worked with was Odd Hassel. They found that in molecules with fixed rings, there was a relationship between configuration and confirmation. Once the confirmations could be found for a molecule, the configuration of that molecule could be found. This is when the whole subject of conformational analysis started, which lead to the Nobel Prize of 1969. Derek Barton had two marriages, his first to Jeanne…

table of elements The periodic table of elements is an organized table of all chemical elements identified and recognized. Most forms of the table commonly include information such as each element’s atomic number, chemical properties, and electron configuration. Prior to the periodic table, the elements were arranged in groups of three called triads. These triads were created by Johann Dobereiner, a German chemist, in 1829. Dobereiner arranged these elements in groups of three based on patterns…

valence electrons, just as the Noble Gases. This “Octet” rule governs modern chemistry and all the laws of the universe. In 1868, a scientist named Pierre Jansen discovered something very out of the ordinary.…

Animal Behavior Objectives Define fixed action patterns and give an example. Fixed action patterns (FAP) are innate behavioral sequences of an individual within a species that consistently displays these sequences with a regular pattern of behaviors carried out to completion. These behaviors are prompted by a “releaser,” which is a specific sign stimulus. This prevents energy waste within the individual, and hence the species. An example of a fixed action behavior is a female turkey’s mothering…

frame made out of Platinum. Platinum has many common compounds but most of them are variations of compounds between Platinum and Flourine, Chlorine, Bromine, and Iodine. Platinum has 78 protons and 78 electrons when neutral. Its Noble Gas configuration is; [Xe] 6s2 5d8. Its Electron Configuration is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 4f14 5d8. Platinum has 6 natural isotopes, 190Pt, 192Pt, 194Pt, 195Pt, 196Pt, and…

particles such as electrons, protons, and neutrons. The protons and neutrons of the atom make up its center, called the nucleus, and its electrons surround the nucleus from a certain distance.…
