Chem 210 Final Exam Questions and Correct Answers, With Complete Solution, 2024. SOPBAR used to find degrees of unsaturation ((2C+2)-H-X+N)/2 Resonance Rules -no breaking single bonds -do not exceed octet -keep net charge the same -try to have full octets (most stable) Resonance Patterns 1. Lone pair e- next door to pi bond 2. Pi bond next to positive charge 3. Double bond btwn atoms of differing electronegativity (ex: carbonyl) Curved Arrows show movement of pair of electrons s...

1 lb = _______ kg - 0.454 5 steps of creating a Lewis structure - 1. calculate total number of valence electrons available 2. determine which will be the central atom 3. arrange atoms symmetrically around the central atom 4. place bonds/electrons around the atoms until the octet rule is satisfied for each atom, using double or triple bonds if necessary 5. show any charges on the molecule by using brackets and writing the charge in the top right corner outside the brackets acid + base --&...

Covalent bonds - CORRECT ANSWER-Covalent compounds are formed when nonmetals share valence electrons forming a covalent bond. Ionic bonds - CORRECT ANSWER-Ionic compounds are formed when metal atoms transfer electrons to nonmetal atoms resulting in the formation of ionic bonds. Covalent bond - CORRECT ANSWER-Share electrons with nonmetal to form a covalent bond Ionic bond - CORRECT ANSWER-transfer electrons from metal to nonmetal to form covalent bond - electron donor and an electron ac...

Induction Specific to general Deduction General to specific Archae/Bacteria Prokaryote. One-cell. No nucleus. Eukarya Eukaryotes. Multi-cell. Has a nucleus. Protons Found in nucleus. Positive charged. Nuetrons Found in nucleus. Neutral charge. Electrons Found in outer shells. Negative charge. Atomic Number Number of protons. Never varies.Atomic Mass Number of protons and neutrons in the nucleus. To determine number of nuetrons, subtract Atomic Mass from Atomic Number. Electron Shells Po...

Which one of the following lists shows the correct order of biological organization? - Population, community, ecosystem, biosphere A modification that makes organisms more suited to their environment is called a/an: - Adaptation During a scientific experiment, the control group is: - Identical to the experimental group in all areas except the variable being tested When an atom has 2 or more electron shells, the outer shell will be most stable if it contains 8 electrons. This concept is cal...

the octet rule is correct answers when atoms bond, they lose, gain, or share electrons to get a full outer (valence shell) energy level which has 8 electrons to start a lewis structure, pick the atom that is usually correct answers the least electronegative (except H) the first in the formula lowest group number if the two atoms are in the same group correct answers select the one in the highest period To avoid the wrong number of electrons you should correct answers count the electro...

Chapter 1 Carbon and Its Compounds CHECKPOINT PROBLEMS Practice Problem 1.1 a) S — 1s2 2s2 2p6 3s2 3p4 b) Cl — 1s2 2s2 2p6 3s2 3p5 c) Na+ — 1s2 2s2 2p6 1-2 Copyright © 2018 Nelson Education Limited Practice Problem 1.2 a) Count valence electrons. Build a basic bonding framework and account for electrons used. Add remaining electrons and check for formal charges. The molecule has a lone pair on the nitrogen. All other electrons are bonding electrons. b) Count valence electrons. Build a bas...

Summary C 844 Emerging Technologies in Cybersecurity Task 1. Latest.A. Describe the network topology you found when running Nmap. Include screenshots as evidence of running Nmap. In order to see the network topology, I used the Zenmap version of nmap to run the scan on the network. As seen in the image below, the network is set up in a star topology. The central device in the star network is host 192.168.29.2, with 9 devices connecting to it. All the devices are under the 192.168.27.x subnet, ...
