Atoms
The smallest particle of an element that retains the element's properties.
What is an atom?
What is the Law of Conservation of Mass?
An ion compound of more than one atom.
What is a polyatomic ion?
Hydrogen, Nitrogen, Oxygen, Fluorine, Bromine, Chlorine, and Iodine.
What are the diatomic molecules?
Measuring the amounts of elements and compounds involved in a reaction.
What is stoichiometry?
A measure of the concentration of solute in the solution.
What is molarity?
The small positively-charged center of the atom.
What is the nucleus?
Two or more substances combine to form one substance. A + X -> AX.
These tell us what compounds are able to be dissolved in water. They have an order and they have lots of expectations.
An atom cannot exist by itself.
A collection that contains the same number of particles.
What is a mole (mol)?
The measure of how much solute is dissolved in a specific amount of solvent or solution in total and it can be expressed in many different units.
Identifies each isotope of an element.
One substance reacts to form two or more substances. AX -> A + X.
What is decomposition?
All salts containing: Ammonium, NH4+, and Group 1A ions: Li+, Na+, K+, Rb+, Cs+.
What is rule #1 of the solubility rules?
One element displaces another in a compound. A + BC -> AC + B.
What is single-displacement?
6.022x1023.
What is Avogadro's number?
Defined as the negative logarithm (log) of a hydronium ion concentration.
What is pH?
The weighted average mass of the isotopes of a specific element.
What is the atomic mass?
Ions of two compounds exchange places with each other. AX + BY -> AY + BX.
What is double-displacement?
SO42-.
What is the element for sulfate?
They have different reactivates and do not always replace each other.
States a specific number of items.
What is a collection term?
Similar to the pH scale, expect that it's associated with the OH concentration of an aqueous solution.
What is the pOH scale?
Protons - Electrons.
What is the charge?
This results when a hydrocarbon combines with oxygen. O2 -> H2O + CO2.
What is combustion?
BO33-.
These will not always replace themselves in a compound dissolving in water because of differing reactivity.
What are metals?
1 nitrogen atom and 1 oxygen atom.
What is NO?
A term that comes from the Latin word acidus, which means "sour."
What is acid?
