(DONE) Lecture 12 + 14 + 15 Flashcards
1
Q
List the prefixes that indicate the number of each element up to 8
A
- mono
- di
- tri
- tetra
- penta
- hexa
- hepta
- octa
2
Q
define: electrolyte
A
- substance whose aqueous solutions conduct electricity due to a presence of charged particles in the solution
3
Q
synthesis reaction
A
2 substances combine to create a new substance
4
Q
decomposition reaction
A
1 compound breaks into 2 or more substances
5
Q
replacement reaction (single and double/metathesis)
A
- A single element exchanges with a part of a compound
- 2 compounds exchange parts
6
Q
combustion reaction
A
- the reaction of an element or compound with oxygen at high temp
7
Q
acid base neutralization reaction
A
acid + base –> salt and water
8
Q
explain oxidation and reduction reactions and the difference between the two
A
- transfer of electron reaction
- oxidation: loss of electron(s)
- reduction: gain of electron(s)
- OIL RIG (oxidation is loss, reduction is gain)
9
Q
precipitation reaction
A
- the mix of 2 solutions that involves the formation of a solid (insoluble) compound
10
Q
define a solution
A
- homogeneous mixture of 2 or more substances
- 1 phase
- concentration given in molarity
11
Q
differentiate between a solvent and a solute
A
- component of a mixture in the greatest amount
- component with the smaller amount
12
Q
In an aqueous solution, what is the solvent?
A
- water
13
Q
Define solubility
A
- the maximum amount of solute that will dissolve in a given amount of solvent
14
Q
Define a saturated solution
A
- solution containing the max amount of dissolved solute
15
Q
What factors impact solubility (3)?
A
- Degree of subdivision of particles of the solute (greater the surface area the more it dissolves)
- Agitating the solution (stirring)
- Temperature (higher temp= molecules move rapidly so rate of solute solvent interactions increase, higher rate of solubility
