loss of electrons
what is reduction
gain of electrons

please stop calling me a careless zebra, instead try learning how copper saves gold
what is a displacement reaction
when a more reactive metal displaces a less reactive metal
how are unreactive metals found
in the earth as an ore
how can metals less reactive than carbon be extracted
reduction with carbon
what do acids produce when reacting with some metals
salts and hydrogen

what is the pH scale
0 to 14, is a measure of the acidity or alkalinity of a solution, and can be measured using universal indicator or a pH probe
what happen in a neutralization reaction
hydrogen ions react with hydroxide ions to produce water
what are strong acids
they are completely ionized
