Oxyacids - Study guides, Class notes & Summaries

Anions are - negative (ie, more electrons) Cations are - positive (ie, less electrions) Formula for density - d = m/v Formula Mass is measured by - adding up all the elements g/mol Formulas to conv. Celsius to Fahrenheit - 1. F = (C x 9/5) +32 2. C = (F +32) x 5/9 Formulas to conv. Kelvin to Celsius - C = K - 273.15 How do you find percent composition? - (# of element)(atomic mass of element) / (mass of entire compound) and then multiply by 100 How to find neutrons in an isotope? - numb...

Physical change - correct answer A change in the size or form of a substance. No new substance is formed. Chemical change - correct answer A new substance is formed. How to tell chemical change? - correct answer Precipitate, change in color, gas formed, heat and light, and difficulty to reverse change. Isotopes - correct answer Atoms of the same element having the same number of protons and electrons but a different number of neutrons Ion - correct answer A charged Atom Cations - ...

These are slides that my teacher made for the class. They are really well done with lots of examples, definitions for everything, and everything you need to know from the book. I didn’t use a book for this class, it wasn’t needed. These slides should cover about %95 of the material your class is covering or will cover because it only goes over the very important stuff that will stay with you if you move up to the next class, and just core concepts of general chemistry. Other stuff is left ou...

Includes everything from first few weeks in General Chemistry; from the atom to nomenclature.

General Chemistry Questions & Answers Acid Dissociation Constant, K(a) - CORRECT ANSWER - Equilibrium constant for an acid in water. HA + H2O --> A- + (H3O)+ K(a) = [H3O+][A-]/[HA] Acid Strength of Molecular Structure - CORRECT ANSWER - Molecular structure determines whether or not a molecule will release its hydrogen into solution with three factors: 1) Strength of the bond holding the H onto the molecule. 2) Polarity of the bond. 3) Satbility of the conjugate base. Hydrogen halide...

I have prepared full chapter notes on s-BLOCK ELEMENTS (Alkali and Alkaline Earth metals) Group 2 elements, covering topics such as alkaline earth elements, electronic configuration, ionization enthalpy, hydration enthalpy, physical properties, chemical properties, uses, general characteristics of compounds of the alkaline earth metals (oxides, hydroxides, halides, salts of oxyacids such as carbonates, sulphates, and nitrates), anomalous behavior of beryllium and its diagonal relationship with a...

Class notes for Chapter 8: Solutions and Aqueous Reactions in the class General Chemistry: Macroscopic Investigations and Reaction Principles (CHEM 130) at the University of Michigan. Topics covered include solutions and solution concentration/dilutions, aqueous solutions, precipitation reactions, acid-base reactions, gas-evolution reactions, oxidation-reduction reactions, and redox reactions.

Chapter 1 covers common and popular atomic theories and the atomic structures, atomic weight, how to find mass and subatomic particle amount in any element, naming compounds, navigating the periodic table, naming acids, and using prefixes for molecular compounds.
