August 23, 2016 Basic Chemistry  Key Terms o Cation- A positively charged particle. o Anion- A negatively charged particle. o Ion- A charged particle. o Atom- The smallest particle that exists. o Molecule- the smallest particle that exists in free state. o Homogeneous Mixture- a mixture that becomes one solution. (Sugar and Water) o Heterogeneous Mixture- a mixture that has two separate components. (Sand and Water) o Solute- The minority component of a solution. o Solvent- The majority component of a solution.  Periodic Table of Elements o Each column in the table is a Group. o Each row in the table is a Period. o There are three types of elements when it comes to a metal status.  Metal  Non-Metal  Metalloid (some properties of metal and non-metal) o Elements with red element symbols are a gas at room temperature (25°C). o Elements with blue element symbols are a liquid at room temperature. o Elements with black element symbols are a solid at room temperature. 1 Atomic H Element Hydrogen Element 1.00794 Atomic  Elements That Exist as Diatomic Molecules (They cannot stay by themselves as a single atom) Molecular Element Symbol Formula Normal State Hydrogen H H2 Colorless Gas Nitrogen N N2 Colorless Gas Oxygen O O Colorless Gas 2 Fluorine F F2 Pale-Yellow Gas Chlorine Cl C2 Reddish-Brown Bromine Br Br2 Liquid Iodine I I2 Bluish-Black Solid 1 o Farah’s Brother Is Cleaning Out His Nissan  Common Acids (Water or aqueous solution) Anionic Group Formula Acetic Acid Formula- Acetate HC 2 3 2 Nitric Acid C2H3O 2 Nitrate HNO 3 Chloric Acid NO 3- Chlorate HClO Carbonic Acid ClO - Carbonate 3 2- H 2O 3 Sulfuric Acid CO 3 Sulfate H 2O 4 Phosphoric Acid SO 4- Phosphate H PO Hydrochloric PO 3- Chloride 3 4 - HCl* Acid Cl Name Name** *When Hydrogen breaks off of a compound, it becomes cationic (H ) + *Binary Acid (Does not contain any oxygen in it) a non-oxy acid. **When thinking of anionic groups that contain oxygen, think oxygenate. o The number of hydrogen atoms in the compound directly correlates with the anionic charge. o The total charge in a compound is zero. o pH measures the hydrogen ions in a solution. o How do you know if a compound is an acid?  The first element is hydrogen (H)  It is dissolved in water (aq)  Common Bases + Formula Name Ammonium NH 4is a Hydroxide polyatomic cation NaOH Sodium Hydroxide NH 4H - OH Hydroxide August 25, 2016 Chapter 2: Measurement and Problem Solving Coountabll Numbers ending Numb Number Measura Unit Significant Figures: any # between 1 and  Significant Figures o How to handle “zero” in the number system:  Trapped zero (i.e.: 303) 2  Trailing zero (i.e.: 1.000 [so any number, decimal point, then any zeros])  Leading zeros are not considered significant figures (i.e.: 0.15—only two sig. figs.) o Calculations:  Addition and Subtraction- Round off to the least number of sig. figs. after the decimal point  Multiplication and Division- Round off to the least number of total sig. figs. Addition/Subtraction Multiplication/Division 3.35 2 sig. figs. 5.75 3 sig. figs. 15.0 1 sig. fig. x 3.2 2 sig. figs. + 123.525 3 sig. figs. 18.40 (rounded to 18) 141.875 (rounded to 141.9) 3   Scientific Notation o Used for either really large numbers or really small numbers. o When adjusting a number into scientific notation, you want to turn it into a number between 1 and 9.  65,397  6.5397 x 10 -3  0.00782  7.82 x 10  Units of Measurement  English versus Metric  Weight/Ma  Pounds (lbs.), Ounces  Grams (g) ss (oz.)  Length  Feet (ft.), Inches (in.)  Meters (m)  Volume  Ounces (oz.)  Liters (L) (liquids)  Temperatur  Fahrenheit ( F)  Celsius ( C) e  **Kelvin (K) is the Absolute Temperature Scale; does not use degree signs   Conversion Factor  (unit given)*(conversion factor)=unit needed  i.e.: 5.70 ft.  cm  1 ft.=12 in.; 1 in.=2.54 cm 12∈. 2.54cm  (5.70 ft.)*1 ft) *( 1∈. )=173.736 cm 174 cm 4
