Analyze the charges of Sodium and Chlorine after the octet rule has been performed.
Sodium +1
Chlorine -1
Because Sodium is losing a valence electron and chlorine is gaining one, Sodium would have a +1 charge and chlorine would have -1

Predict if these two elements will form an ionic compound. Lithium and Fluoride
Yes, they form LiF or "Lithium Fluoride".
Ionic compounds are made up of ions and lithium and fluoride are both ions.

Compare and contrast the physical and chemical differences of Ionic and Covalent Compounds
Ionic has a higher melting point than covalent
Ionic Compounds have a higher boiling point
Ionic compounds conduct electricity
Ionic compounds are hard and brittle
Ionic is composed of a metal and nonmetal
Covalent is composed of a nonmetal and a nonmetal

Determine the product of Bromine reacting with Sodium Iodide
Justification: This is a single replacement reaction
Br2+ 2NaI → 2NaBr + I2

Using the coefficients in the equation, what is the ratio of H2 and H2O
_H2+_O2=_H2O
2:2
Since oxygen on the reactants side has a subscript of 2, you need to add a coefficient of 2 in the reactant to make it equal. That coefficient will make Hydrogen 4, so you need to add a coefficient of 2 to hydrogen on the reactants side.

Compare and contrast similarities between metals and nonmetals
Similar: can change states, have solid and liquid form
Difference: Metals are malleable, shiny, ductile while Nonmetals are soft brittle and low density

What is the molar mass of Tin (IV) chloride? Show your work
260.5 g/mol
Tin 118.71 + and 4 chlorine atoms of 35.453 = 260.5

Draw the lewis diagram for Phosphorus Trichloride and name the molecular structure.
This Photo is after applying the Octet Rule
Since Chlorine has 7 valence and there are 3 of them, and Phosphorus has 5 if they share one to each everything will become balanced
It is Trigonal Pyramidal because it has a lone pair

Name the seven diatomic particles.
H2, O2, F2, Br2, I2, N2, and Cl2 They contain 2 atoms that are chemically bonded, therefore they are di “two” atomic

Match the following chemical reactions to the correct term
A: H2+O2 = H+O
B: 2HCl +Zn = H2+ZnCl2
C: KCl+AgNO3 = KNO3+AgCl
D: CH4+O2 = CO2+H2O
E: C12H22O11= 12C + 11H2O
Double Replacement
Synthesis
Single Replacement
Combustion
Decomposition
A: Combustion
B: Double Replacement
C: Single Replacement
D: Synthesis
E: Decomposition
Combustion - substance reacts with oxygen releasing energy and heat
Double Replacement - the cations switch places
Single replacement - element in a compound is replaced by another
Synthesis - two or more reactants form one product
Decomposition - one reactant forms two or more products

How do you name binary compounds?
Metal name + Non metal with IDE ending
When naming binary compounds, combine the metal’s name with the non-metals name with IDE ending
300
Name SO3
There is 1 Sodium and 3 Oxygen therefore the prefix would be “Tri”
There is 1 Nitrogen and the prefix “Mono” tells there is 1 Oxygen therefore making it Nitrogen Monoxide

Apply the principle of the “Law of Conservation of Mass” to explain how this equation is balanced.
Fe+O2=Fe2O3
On the reactants, You need to add a coefficient of 4 in front of “Fe” and a 3 in front of O2. On the products you need a Coefficient of 2.
The law of conservation of mass states mass cannot be created nor destroyer, by adding subscripts we ensure that the products are equal to the reactants.

Evaluate what the formula is for Cobalt (II) Chloride
CoCl2
It is CoCl2 because cobalt charge is 2 and is the metal cation

Determine the Molar Mass of Phosphorus Trichloride
137.333
1 Phosphorus = 30.974
3 Chlorines = 106.359
= 137.333

Balance the following equation with coefficients. Al+O2 =Al2O3
4Al + 3O2 = 2Al2O3
There are 4 Aluminums on each side and 3 oxygens, therefore the equation is balanced.

Use the metal activity series to determine if the single replacement reaction occurs in the chemical equation Cu + 2FeNO3
No Reaction
Copper can’t replace Iron because according to the metal activity series, copper is listed lower than iron
