Bonds Flashcards
Name the two types of bonds
Covalent bond
Ionic bond
How do you draw ionic bonds?
Draw the elements using the Lewis Structure
You must show the new charge of each element
The arrows showing the movement of electrons
You must use brackets
What characterises a covalent bond?
True partnership, only lightning can separate them
What forms ionic bonds?
Metals and nonmetals
They GIVE electrons to eachother
How do you draw covalent bonds?
Draw the elements using the Lewis Structure
You must show the SHARING of electrons with circles (hugs)
WHat forms covalent bonds?
Transition metal or nonmetal or polyatomic
+
Nonmetal
What characterizes an ionic bond?
Opposites attract, separates when in contact with water
How do you name ionic bonds?
NO PREFIXES
When do you use roman numerals when naming?
WIth transition metals
Name the polyatomic ions
Nitrate Carbonate Phosphate Sulfate Ammonium Hydroxide
Which polyatomic is POSITIVE?
Ammonium
What do roman numerals signify in naming?
The individual charge of each transition metal
How do you remember the charges for the polyatomic ions?
Nick the Camel ATE a Phoenix for Supper
How many parts in a mole?
6.02x10*23 parts
How do you name covalent bonds?
USE PREFIXES!
mono, di, tri, tetra, penta, hexa
What is Molar Mass?
One mole of C has 12.01g - the atomic mass
What is very important when calculating on a calculator?
USING BRACKETS!!!
How do you prove a molecular formula?
USING LEWIS STRUCTURES
In calculations always write____
UNITS
What should you do when naming a bond?
Identify each element and write down their rules!
Can you go from Grams to particles directly?
NOOO
You need to go from grams to moles and then moles to particles
I can’t show how to do calculations on this so just review your notes for that
if u need help reach out ma dudes
What is HCl called?
Hydrogen Chloride
What is NaOH called?
Sodium Hydroxide
What is an Acid?
when the pH is lower than 7
If the pH is 10 what is it?
a base
When is the pH neutral?
when the pH is 7
How does a solution conduct electricity?
Through the presence of dissolved ions or ions that have dissociated. The ions are electrically charged and, in the presence of electric current, they start to MOVE. The current can then flow through the solution.
Is ZnSO_4 a salt?
yep
Do ionic or covalent bonds conduct electricity?
Ionic, because they break in water
When dissolved in water _________ break up completely into ions, while _________ break up partially into ions.
Strong electrolytes, weak electrolytes
How can you identify an acid?
Presence of H+
at the beginning
How can you identify a base?
Presence of OH-
at the end
The H+ concentration of a pH 5 solution is:
10*-5 mol/L
The OH- concentration of a pH 11 solution is:
10*-3 mol/L
A pH 4 solution contains an H+ concentration ______ than does a pH 5 solution contain.
10 times higher
