CHEM 120 Final Exam | Questions and Correct Answers | Latest Update 2024/2025 | 100% Pass B - Answer -How many bonds can nitrogen have? Which rule or principle should be used? A) Five bonds; octet rule. B) Three bonds; octet rule. C) Three bonds; the Hund's rule. D) Five bonds; the Aufbau Principle. C - Answer -When two hydrogen atoms meet, they will attract to each other and form a bond (and a H2 molecule). Why? A) Because electrons like to stay together. B) Because electrons li...

Gaining vs. Losing electrons - ️️N+1 = Losing electron N-1 = Gaining electron Electrons = electronegative Octet rule - ️️Atoms are most stable when their outer shell is full. The outer shell has to be filled with 8 electrons EXCEPT Hydrogen and Helium with just 2 electrons. Three Physical States of Matter - ️️Solid, liquid, gas Element - ️️Substance that cannot be broken down into other substances by chemical reactions Matter - ️️Anything that occupies space and has a...

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, so for simplicity I will refer to the device by the ID of the la...

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 --&...

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...

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...

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...
