Precipitation
a solid compound is formed from two aqueous solutions
Neutralization
an acid and a base react to form a salt and water
oxidation
loss of electron
reduction
gain of electron
Redox (reduction-oxidation)
electrons are exchanged between atoms in the reacting compounds.
How do you find the molar mass of a compound
add up the atomic mass for each atom in the compound
Define Stoichiometry
The use of balanced chemical equations for quantifying the amount of materials in a given chemical reaction.
Why can’t a chemical equation be balanced by changing the subscripts of the reactants and / or products?
Because changing the subscripts means changing the identity of the chemicals
Ionic compounds are made up of ?
I metal (or transition metal) and 1 nonmetal
Covalent Compounds are made up of ?
2 nonmetals
Which type of compound uses prefixes like mono, di, and tri?
covalent
Ionic compound must be (BLANK)
Neutral (a + charge has to cancel out a - charge)
What must be included in the formula of any ionic compound?
A cation and an anion, written cation first, followed by anion.
What ionic compound was found in George Trepal’s garage?
Thallium (I) nitrate.
What is the phenomenon when cations and anions are arranged in a repeatable, three-dimensional pattern?
a crystal lattice
The limiting reagent is the
actual yield
Cation
