Chem Chapter 7+8

What is a cation? A positive ion.
What is an anion? A negative ion.
How do you name monoatomic cations? Just name the element.
How do you name monoatomic anions? Keep the root name and add -ide. N = Nitride H = Hydride
How do you name elements with multiple charges? Co+2 = Cobalt (II) Co+3 = Cobalt (III) Sn+2 = Tin (II) Sn+4 = Tin (IV) Cu+1 = Copper (I) Cu+2 = Copper (II)
How do you name simple compounds? Always name cation first. Anion takes root + -ide. CsBr = Cesium Bromide CuCl = Copper (I) Chloride CuCl2 = Copper (II) Chloride
What is an oxyanion? A polyatomic ion that contains oxygen.
How do you name oxyanions? The name of the ion with the greater # of oxygen atoms ends in -ate; the name of the ion with the smaller # ens in -ite.
What is a binary covalent compound? A compound formed between two non-metals.

What does a Chemical Formula Tell Us? The number of atoms in a compound or molecule. ex NaCl = 1 Na; 1 Cl H2SO4 = 2 H; 1 S; 4 O
Formula Mass the sum of the atomic masses of the all atoms present. Has the units AMU ex HNO = 63 AMU
**Molecular formula? moles = grams/molar mass
NO3 (-1) Nitrate
NO2 (-1) Nitrite
SO4 (-2) Sulfate
SO3 (-2) Sulfite
PO4 (-3) Phosphate
PO3 (-3) Phosphite
ClO (-1) Hypochlorite
ClO2 (-1) Chlorite
ClO3 (-1) Chlorate
ClO4 (-1) Perchlorate
Cr2O7 (-2) Dichromate
MnO4 (-1) Permanganate
C2H3O2 (-1) or CH3COO (-1) Acetate
NH4 (+1) Ammonium
O2 (-2) Peroxide
CN (-1) Cyanide
Formula for % of element in a compound? mass of element in compound/mass of compound x 100
Empirical Formula Ratio of atoms in a compound ex glucose - CH2O
Molecular Formula Shows the actual number of atoms in a compound ex glucose - C6H12O6
How do i find the molecular formula? Divide the molar mass by the molar mass of the empirical formula, then multiply the empirical formula by the resulting integer
Name the Drivers for a chemical Reaction (6) 1. Color Change 2. Formation of a gas 3. Formation of a solid 4. Formation of H2O (water) 5. Transfer of electrons (Oxidation Reduction Reaction or Redox) 6. Evolution of energy in the form of heat or light
A chemical change always involves a? rearrangement of atoms
Law of Conservation of Mass In a chemical reaction, atoms are neither created nor destroyed. There must be the same # of atoms on the product side as the reactant side (balancing equations).
Chemical equation Shows the identities and relative amounts of reactants and products in a reaction using symbols and formulas. ex Zn(NO3)2 + 2HCl --> ZnCl2 + HNO3
Formula Equation With symbols and formulas, shows the reactans and products in a reaction. ex Zn(NO3)2 + HCl --> ZnCl2 + HNO3
What are 4 types of chemical reactions? 1. Formation of a gas 2. Formation of a solid (Precipitate) 3. Formation of Water 4. Transfer of e-s (Oxidation Reduction Reaction or redox)
Other ways to classify reactions? (5) 1. Combustion Reaction 2. Synthesis Reaction 3. Decomposition Reaction 4. Single Displacement Reaction 5. Double Displacement Reaction
Combustion Reaction In a combustion reaction, a substance combines with oxygen, releasing a large amount of energy in the form of light and heat. EX 2H2(g) + O2(g) --> 2H2O(g)
Synthesis Reaction In a synthesis Reaction, aka a composition reaction, two or more substances combine to form a new compound. A + X --> AX
Decomposition Reaction A single compound undergoes a reaction that produces two or more simpler substances. Usually requires heat or an electric current. AX --> A + X
Single Displacement Reaction aka a replacement reaction, where one element replaces a similar element in a compound A + BX --> AX + B
Double Displacement Reaction In a double displacement reaction the ions of two compounds exchange places in an aqueous solution to form two new compounds. AX + BY --> AY + BX
