First year uni paper. lecture notes on atoms and bonding, lewis structures and isomers.

Laboratory 3: Ionic and Covalent Compounds Learning Objectives: • Name ionic and covalent compounds and derive their chemical formulas. • Observe absorption spectra of metal ions using flame test. • Draw Lewis symbols of elements and Lewis formulas of simple covalent compounds. In this laboratory exercise, you will learn how to derive formulas of ionic and covalent compounds and name them. You will also flame test various metal ions and draw models of simple covalent molecules. N...

What is the third most abundant component of dry air? Which Lewis structure below correctly represents KCl? Which of the following statements about pressure is FALSE? The atmosphere has a pressure as the components of air collide with A mothball can change directly from its solid phase to its gaseous phase. This process is known as: A balloon originally had a volume of 0.439 L at 44 °C and a pressure of 729 torr. To what temperature must the balloon be cooled to reduce its volume to 378 ...

CHEM-120 Week 2 Discussion Question 2 – Chemical Structures The electron configuration of an atom determines the number of electrons available to participate in bonding with another atom. One method of depicting the valence electrons that an atom has is through the Lewis structure. To begin this discussion, pick an element from the periodic table of elements. Identify the valence electrons and the orbitals in which they reside. You can use the textbook and lecture.

Chapter One Topic: Introduction to Organic Chemistry 1. Chemical reactions occur as a result of: A) Attraction between opposite charges B) Nucleus–Nucleus interactions C) Motion of electrons D) Like atoms interacting E) Combining two chemicals 2. Credit for the first synthesis of an organic compound from an inorganic precursor is generally ascribed to: A) Berzelius B) Arrhenius C) Kekulé D) Wöhler E) Lewis 3. What was long thought to be the difference between inorganic and organic compo...
