Chemical Reactions
What are the 5 types of Chemical Reactions?
Synthesis, Decomposition, Single Replacement, Double Replacement, and Combustion.
What is a Ion?
Atom or Molecule with a Net Charge.
What type of elements only form Covalent Bonds?
Only Nonmetals.
What is the activity series?
Series of metals arranged from in terms of higher or lower activity.
What does Soluble mean?
Able to be dissolved in water.
What is the general formula for Synthesis?
A + B = AB
How are Ions formed?
Ions separates and form in Water (H2O)
What happens to electrons in a Covalent Bond?
Share e-.
How is the activity series used?
Used to predict products in displacement reactions.
What does Insoluble mean?
What is the general formula for Decomposition?
AB = A + B
What type of elements forms Ionic Bonds?
Metals and Nonmetals.
How do you name Covalent Compounds?
Use prefixes such as Mono(1), Di(2), or Tri(3) for both elements in the compounds.
Where are the most active metals located?
Bottom Left Corner of Periodic Table.
What is a Precipitate?
Cause a substance solidify in a solution.
What is the general formula for S. and D. Replacement?
S. Replacement: Compound + Single Element = Single Element.
D. Replacement: 2 Compounds = 2 Compounds.
What is difference between Anion and Cation?
Anions - Metals that lose e- and are +
Cations - Metals that gain e- and are -
How many bonds can an element form?
2 Bonds - Polar Covalent and Non-polar Covalent Bonds.
Where are the least active metals located?
Top Right Corner of Periodic Table.
What is a Solubility Chart?
A list of ions that tells if the mixed ions become either precipitate or liquidy.
What is the general formula for Combustion?
CxHy + O2 = CO2 + H2O
What happens to electrons in an Ionic Bond?
They give/take (transfer) e-.
What is the difference between bonding and non-bonding pairs?
Bonding Pairs - are even
Non-Bonding Pairs - are uneven
How do you determine which metal is higher or lower in a activity series?
The metal which is on top of the other metal on the activity series has a higher activity than the other.
How do you use Solubility Chart?
Find where your two ions correspond, there it will either say s or aq.
