The extremely small, positively charged, dense center of an atom that contains positively charged protons and neutral neutrons.
nucleus
Avogadro's number
6.02 x 1023
Standard temperature in Celsius.
0 °C
A combination of two or more pure substances in which each substance retains its individual chemical properties.
mixture
A solution with a pH of less than 7
Acidic
The atomic number of carbon.
6
The mass in grams of one mole of any pure substance.
molar mass
Standard pressure in atmospheres.
1 atm
Homogeneous mixture, where the particles are evenly distributed or blended.
solution
A solution that contains more hydroxide ions than hydrogen ions.
Basic
The electrons in an atom's outermost orbitals; determine the chemical properties of an element.
valence electrons
Ratio of aluminum to oxygen in Al2O3
2:3
The volume that 1 mol of gas occupies at given temperature and pressure conditions.
molar volume
Two liquids that can be mixed together but separate shortly after you cease mixing them
immiscible
The Bronsted-Lowry model describes acids as a donor of this element ion.
hydrogen ion
This block of the periodic table contains transition metals.
d-block
Number of moles of hydrogen in 5 moles of water.
10 moles
What happens to pressure for a fixed mass of gas when temperature increases and volume stays the same.
increases
The molarity of a solution made with 1.0 mol in 1.0 L of solution.
1.0 M
This type of acid or base in solution has a high electrical conductivity.

Avagadro's Principle
The scattering of light by colloidal particles
Tyndall effect
The difference in hydrogen ion concentration between a solution with a pH of 5.0 and a solution with a pH of 6.0.
5.0 has ten times the hydrogen ion concentration.
