CHEM 120 Final Exam 5 GRADED A+ (ACTUAL EXAM ) Questions and Answers (Solved) 1. How many bonds can nitrogen have? Which rule or principle should beused? A) Five bonds; octet rule. B) Three bonds; octet rule. C) Three bonds; the Hund's rule. D) Five bonds; the Aufbau Principle. Answer: B 2. When two hydrogen atoms meet, they will attract to each other and form abond (and a H2 molecule).Why? A) Because electrons like to stay together. B) Because electrons like to be paired up. C) Bec...

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...

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...

Organic chemistry: correct answer: The study of carbon-containing compounds except elemental carbon (diamond, graphite, coal), CO2, CO, carbonates, and cyanides. Inorganic chemistry: correct answer: Studies the elements and everything else. The principle components of food, fuels, wood construction, and clothing are organic compounds. Octet rule: correct answer: A chemical rule of thumb that reflects observation that atoms of main-group elements tend to combine in such a way that each a...

Covalent bonds: Covalent compounds are formed when nonmetals share valence electrons forming a covalent bond. Ionic bonds: Ionic compounds are formed when metal atoms transfer electrons to nonmetal atoms resulting in the formation of ionic bonds. Covalent bond: Share electrons with nonmetal to form a covalent bond Ionic bond: transfer electrons from metal to nonmetal to form covalent bond - electron donor and an electron acceptor (cation and anion) Covalent: water, H2O 2 H atoms + 1 O ato...

Friederich Wohler correct answer: Father of organic chemistry Determined that biological molecules can be synthesized in lab Carbon correct answer: Very stable Wants 4 bonds Can bond with many things Organic Compounds correct answer: Contain carbon Atoms bound by covalent bonds Essential to life! ex. amino acids; DNA Element Bond Preferences correct answer: Carbon: 4 bonds -Can be single, double, or triple Nitrogen: 3 bonds, 1 lone pair -Single, double, or triple Oxygen: 2...
