Polar/ Non Polar
If A molecule is evenly spread out does it make polar or non polar?
Non Polor
Name the type of reactions.
Synthesis, Decomposition, Replacement, Double replacement
What does the mole represents?
6.022 X 10^23 particles or 1 mole
What is a chemical equilibrium?
A non dynamic system that is not experiencing major change.
What is Heat of Fusion and Vaporaization?
When a compound transitions from one phase or another and either requires heat energy, or it releases energy.
Why do some molecules have awkward shapes?
Because it has an uneven distribution of postive and negative charges
What is a synthesis reaction also known as?
Combination reaction
What is the number 6.022*10^23 known as?
Avogadro's number
What does "go to completion" mean?
All reactants are used up and they become products
What is a joule?
A joule is a measure of energy. Mostly heat energy.
What is polarity?
A separation of electric charge leading to a molecule or it's chemical groups having an electric dipole moment.
What does all the reactions mean?
Synthesis: A reaction being made
Decomposition: A reaction breaking down.
Replacement: A reaction being replaced with another.
What is the mass in grams of subatomic particle?
1.66*10^-24g
What does LeChatelier tells us?
LeChatelier tells us the reactions towards the Equilibrium
What does table I show on the periodic table?
Table I shows different heats of reactions.
What makes a molecule polar?
One end of the molecule being slightly positive while the other side is slightly negative.
What type of reaction is N2 + H2 --- NH3
Synthesis
What is a Molar mass of a species?
The Molar Mass of a species is the mass of one mole of it's mass expressed in grams
What would the LeChateliers principle do if the reaction is exposed to low temp?
Give a slower reaction.
What number is energy released shown as and what number is absorb shown as?
Energy released is shown as a negative number and absorb is shown as a positive number.
How are some tetrahedron shaped?
Some tetrahedron are shaped like a star while others are in a straight line or in corners
What type of reaction is Na3Po4 + 3 KOH --- 3 NaOH + K3PO4
Double Replacement
What is the Avogadro's number?
The number of particles in a mole of anything
What does changing the parameters do?
It cause the reaction to favor one direction or the other.
What does water needs to transition from solid to liquid?
it needs 334 Joules for every gram of water.
