Scientific Notation
When a number isn't in scientific notation it is in this.
What is standard form(notation)?
The first column of the periodic table.
What are alkali metals?
A microscopic substance that all matter is made of.
What are atoms?
The ability for a given substance (the solute), to dissolve in a solvent.
What is the definition of soluble?
Determines the amount of product that is formed.
What is the limiting reactant?
1.92 x 105 in standard form.
What is 192,000?
The group(s) that only include nonmetals on the periodic table.
What are halogens and noble gases?
When mixtures are completely mixed together, they're this.
What is homogeneous?
Will not dissolve in a solvent even after mixing (eg; sand and water).
What is the definition of insoluble?
Comes in a greater amount than necessary to react completely.
What is an excess reactant?
The number that indicates how many times a base is multiplied against itself.
What is an exponent?

What is Calcium, 20, 20, 20, and 20?
A solution is made up of these two parts.
What is a solute and a solvent?

What is atomic radius, electronegativity, and right
This pure substance is made of two or more elements joined in a specific way.

The answer to 2.0 x 101 * 1.12 x 105 with the correct amount of significant figures.
What is 2.2 x 106?
An element that has the same atomic number and nearly the same chemical behavior but with a different atomic mass and physical properties.
What is an isotope?
A heterogenous mixture includes colloids, which are particles that don't settle, and particles that settle called this.
What are suspensions?
An ammonium ion plus any ion form a compound which is soluble.
