Term
Composition reaction
Definition
A+X-->AX
Term
Reactions of elements with oxygen and sulfur
Definition
metals combine with oxygen and sulfur to form oxides and sulfides
Term
reactions of metals with halogens
Definition
forms ionic or covalent compounds
Term
synthesis reactions with oxides
Definition
oxides of active metals react with water to produce metal hydroxides.
Term
decomposition reactions
Definition
a single compound undergoes a reaction that produces two or more simpler substances.
AX-->A+X
Term
decomposition of binary compounds
Definition
the decomposition of a binary compound into its simpler elements
for instance, 2 water atoms into 2 hydrogens diatomic molecules and 1 dioxide molecule.
Term
electrolysis
Definition
the separation of a substance via electricity
Term
decomposition of metal carbonates
Definition
produces a metal oxide and carbon dioxide gas
Term
decomposition of metal hydroxide
Definition
produces a metal oxide and water
Term
decomposition of metal chlorates

Term
replacement of a metal in a compound by another metal
Definition
a more active metal can replace a metal in a compound. see activity chart on p. 266
Term
replacement of hydrogen in water by a metal
Definition
the most active metals react vigorously with water to form hydrogen and metal hydroxides.
