Gas and Particulates Flashcards
What is atomic mass?
the average weight of an atom that includes the protons and neutrons measured in grams compared to Carbon
What is Avogadro’s Number?
6.02 x 1023 atoms or 1 mole
Atomic weight of Na
23
Atomic weight of H
1
Atomic weight of C
12
Atomic weight of N
14
Atomic weight of O
16
Atomic Number
number of protons found in the nucleus of an atom
Valence Electrons
Electrons in the outer shell of an atom
Ionic Bonds
two atoms exchange electrons
Colavent Bonds
two atoms share electrons
Molar Mass
grams per mole
Compound
substance composed of all the same kinds of molecurles
Molecule
is a unit of matter formed by the chemical combination of two or more atoms, usually from different elements
Mixtures
are not compounds. They do not form from bonds but are different element mixed together like a solution. Elements retain their own chemical properties
pH formula
pH = -log|H+|
Acid
pH below 7
Base
pH above 7
Boyle’s Law
at a constant temperature, a fixed mass of gas occupies a volume that is inversely proportional to the pressure exerted upon it
Boyle’s Law Formula
P1V1 = P2V2
Charle’s Law
At constant pressure, the volume occupied by a fixed mass of gas is directly proportional to the absolute temperature
Charle’s Law Formula
V1/T1 = V2/T2
Ideal Gas Law
a gas where all internal energy is kinetic energy form and any change causes a change in temperature
Ideal Gas Law formula
PV = nRT
R (Universal Gas Constant)
8.2145 J/mol K
