C10H12N2O
How many bonds does a tetrahedral carbon have?
There are 4 atoms bonded.
What is a chemical reaction?
The atoms and the enviroment.
What are the 4 types of Intramolecular bonds?
Ionic, Polar covalent, Nonpolar covalent, and metallic
What molecule is this: MgSO4?
Magnesium Sulfate
How do you tell if a carbons structure is linear?
There has to be 3+ atoms that form a line.
What happens to matter during a chemical reaction?
Matter changes forms when undergoing a chemical reaction. Matter is not gained or destroyed.
How do atoms depend on covalent bond strength?
Bond order - how many bonding electron pairs are between 2 atoms
Bond length - distance between 2 atoms' nuclei
Bond energy - strong bond equals high energy
How are electrons shared/transferred in a Polar covalent bond?
They are unequal transfer/shared.
What is the difference between monatomic and polyatomic ions?
Monatomic = an ion with 1 element
Polyatomic = an ion with more than 1 element
What is the bond angel of a bent nitrogen?
120 degrees
What is the saying for acid base reactions?
Do as you ought to, add acid to water
Will an ionic compound dissociate easily, if so in what substance?
Yes, in water.
What are the 3 types of Intermolecular bonds; in order of bond strength? From weakest to strongest
Dispersion, Dipole - Dipole, Hydrogen bonds
Cross and Drop: Be+2 N-3
Be3N2
How many lone pairs does a planar oxygen have?
There are 2 sets of lone pairs - 4 in total
What happens in a decomposition reaction?
The reactant is broken down into 2 or more smaller products.
Which distance between nuclei is stronger triple or single bond?
A single bond, because there is less area to travel.
What is a dipole?
Area with a positive property on one side and a negative property on the other side.
Cross and Drop: Al+3(OH)-1
Al(OH)3
Will hydrogen ever have a molecular shape?
No, because it is never a central atom.
What is the reaction equation for a double displacement reaction?
AB + CD ---- CB + AD
If ionic compounds dissociate easily in water what will the reaction equation look like if sodium chloride and water mix?
NaCl + H2O ---- Na+ + Cl-
