-is used to describe the column in which an element is in.
i.e., Lithium is in group 1.
*Group number tells you how many valence electrons a specific element has.
i.e., Aluminum has 3 valence electrons. B) Ionic Bonding
-Ionic bonds form F.U.'s (formula units)
-A bond between a metal and a non metal
-Occurs when an atom has lost or gained an electron
**BRING YOUR ION SHEET FOR NAMING** C) Covalent Bonding
-Covalent bonds form molecules.
-Bond between two metals or two nonmetals.
-Electrons are shared between the two elements.
**NEED TO KNOW HOW TO DO A LEWIS STRUCTURE** Part II: Types of Reactions
(You'll need to identify the type of reaction and predict the products) A) Single Replacement
-these can be cationic or anionic.
i.e. Cationic: A+BC-->AC+B Anionic: A+BC-->AB+C
B) Double Replacement
-AB+CD-->AD+CB
C) Composition/Synthesis
-A+B-->AB
D) Combustion
-C(x)+H(y)+O(2)-->CO(2)+H(2)O
Part III: Stoichiometry A) All conversions using the mole, including GFM.
-Mole (Avogadro's #) = 6.02 x 10^23
QUANTITY MOLE MASS
GFM: Number on periodic table. B) Conversions using 1 mole = 22.4L (self explanatory) C) Conversions i.e. 2Bread + 3PeanutButter --> 1Sandwich
How many pieces of bread are required to make 6 sandwiches if I have an excess of peanut butter? 6 sandwiches x 2 bread = 12 Breads. 1 sandwich More examples? Ask. D) Limiting and Excess Reactants Some chemical reactions involve random amounts of reactants. The reaction will stop when one or more of the reactants run out. (limiting) ex. 2Bread + 3 HamSlices --> 1Sandwich How many sandwiches can you make from 21 pieces of ham and 20 pieces of bread? 20B x 1S = 10S 21H x 1S=7S 2B 3H The smaller of answer from the 2 givens is the answer. The reactant that produced the smaller amount is called the limiting reactant. (in this case, ham) Part IV: Gas Laws A) Boyle's Law: States tgat pressure varies indirectly with volume. (In other words, as one goes up, the other goes down.) P(1)V(1) = P(2)V(2) B) Charles' Law: States that temperature varies directly with volume. (In other words, when one goes up, the other goes up.)
*TEMPERATURE MUST BE IN KELVINS V(1)/T(1) = V(2)/T(2) C) Combined Gas Law: Gay Lussac's Law.
-Pressure and temperature are directly related. P(1)/V(1) = P(2)/V(2) THE COMBINED GAS LAW: P(1)V(1)/T(1) = P(2)V(2)/T(2)

In a chemical reaction, the amount of starting material for a chemical reaction limits the amount of product that can be formed.1 The principle of limiting reactants relates to this lab because the limiting reactant is the substance that is used up first in a chemical reaction. The amount of product was limited by that reagent. The excess reactants were considered to be the other reagents that were presented in excess of the quantity that was reacted with the limiting reagent. The theoretical yield was determined as the amount of product obtained when the limiting reagent was completely used. The limiting reagent was identified in order to calculate the percent yield of the reaction.…

Before we start making this sandwich, please make sure you are in the kitchen, we don’t want anything ending up in a toilet or even on Moms brand new sofa. You can take your choice of where you want to be in the kitchen, either at the table or the counter, which ever you prefer. For the sake of keeping everything clean, I am using a paper towel but may use a plate for your sandwich to rest on. So right now please take a plate or paper towel and set it down in front of you.

In a chemical reaction the reactant that runs out first is called the limiting reactant. A personal example would be when I am making candles. I have melted 20 lbs. of wax that yield 24 16 oz. size candle jars. As I am gluing the wicks into the jars I realize that I only have 20 wicks and I need 24 for the amount of wax that I have melted. This means that the wicks are the limiting reactant in my candle making.…
