Lewis Dot Structures
This type of structure uses dots to show valence electrons around atoms.
What is a Lewis dot structure?
A gas is squeezed into a small tube, and its temperature remains constant. What happens to pressure?
What is pressure increases?
What is the term for the distance from nucleus to the outermost electron?
Atomic radius
This increases the rate of reaction without being used up in the reaction.
Catalyst
What has a pH level of 7?
H20
What is Oxygen?
Temperature decreases, what happens to volume?
What is volume decreases?
As you move from left to right on a periodic table, what happens to the atomic radius?
Decreases
State in which both the reactants and the products are present in concentration in which there are no further changes with respect to time.
Equilibrium
Whats the chemical formula for sodium hydroxide and is it an acid or base?
NaOH, Base
In a Lewis dot structure, how many total lone pairs does Carbon have?
What are 2 lone pairs?
What is temperature measured in?
What is Kelvin?
This trend increases across a period and decreases down and describes the energy needed to remove a valence electron.
Ionization energy
This type of reaction has negative ΔH (Change in heat).
Exothermic reaction.
What happens to the concentration of hydrogen ions as pH decreases
Concentration Increases
