⩥ Dispersion Forces
Answer: Sometimes called London dispersion forces, are the weakest of
all the intermolecular forces.
⩥ Stoichiometry
Answer: Deals with the quantities and numeric relationships of the
participants in a chemical reaction
⩥ For a chemical reaction to be balanced, numbers called... are placed
infront of each compound
Answer: coefficients
⩥ Oxidation/reduction reactions are called...
Answer: redox, involve the transfer of electrons from one element to
another
⩥ Oxidation (O.I.L)
,Answer: Loss of electrons
⩥ Reduction (R.I.G)
Answer: Gain of electrons
⩥ The element that is oxidized
Answer: loses and electron
⩥ the element that is reduced
Answer: gains an electron
⩥ Acids
Answer: Corrosive o metals, they change blue litmus paper red and
become less acidic when mixed with bases
⩥ Bases (Alkaline Compounds)
Answer: are substances that denature proteins, making them feel very
slick; they change red litmus paper blue and become less basic when
mixed with acids
⩥ What are Hydrogen or proton donors?
Answer: Acids
, ⩥ Hydronium
Answer: is a water molecule plus a proton or hydrogen
⩥ ....are Hydrogen or proton acceptors
Answer: Bases
⩥ Concentration of acids is expressed as
Answer: pH
⩥ Neutral
Answer: Solution that is neither acidic nor basic has a value of 7
⩥ Lower numbers mean more
Answer: Acidic
