Question 1

Diatomic Molecules

Answer 1

Iodine
Nitrogen
Bromide
Chloride
Hydrogen
Oxygen
Fluoride

Question 2

Ionic compounds

Answer 2

Metal & Non-metal

They must equal 0

Na+Cl= NaCl

Question 3

Molecular Compunds

Answer 3

Two N.M + N.M

Question 4

Cross-Over Rule

Answer 4

Metal first than non-metal

If the same number they will cancel out

Question 5

Binary compounds contain metals

Answer 5

A) Metal/positive ion + Non-metal/negative ion
B) metals with more than one

Metal higher charge “ic”
Lower charge “ous”

Question 6

Question 15

Combination Reaction

Answer 15

A + B = AB
Metal + Oxygen = metal oxide
Metal + N.M = salt

Question 16

Decomposition Reaction

Answer 16

AB -> A + B

Compound to elements

Question 17

Single Displacement

Answer 17

A + BC -> B +AC
OR
A + BC -> C + BA
Activity Series
*switch if metal is higher up on series chart*

Question 18

Double Displacement

Answer 18

AB + CD -> AD + CB
solubility table
Ex) metal oxide and acid
CuO + HNO3 -> Cu(NO3)2 + H2O

Question 19

Activity Series

Answer 19

Use during single displacement

Question 20

Solubility Table

Answer 20

Use during double displacement 
If both (aq) = no reaction occurs

Question 21

Combustion Reaction

Answer 21

Only 2 products
CH4 + O2 -> CO2 + H2O
Complete reaction always equals = water & Carbon dioxide

Question 22

Heat Chemical Reactions

Answer 22

Exothermic= heat giving off ( burning wood)

Endothermic= Absorbs heat, needs more to keep it going. ( Needs heat)

Question 23

Ions

Answer 23

Cations are positives+3 (ium)
Anions are negatives -1 (use)

*formed by adding or removing electrons
