What is a synthesis reaction?
two or more substances combine to form a new compound.
What is the general chemical equation for a Group 2 synthesis reaction that forms a sulfide?
M + S --> MS
What is a decomposition reaction?
a single compound undergoes a reaction that produces two or more simpler substances.
Describe i your own words what happens when solid aluminum is put in a solution of lead (II) nitrate.
More reactive aluminum displaces less reactive Pb(NO3)2 and forms aluminum nitrate.
Explain why the following chem equation is true: Br2 (l) + KCl(aq) --> no reaction
Because Br cannot displace Cl because it is less reactive.
List three forms that the products of a double displacements reaction usually take.
1. Precipitate
2. Insoluble gas
3. Other molecular compound like water
What is the difference between a single replacement reaction and a double replacement reaction?
In single displacement: one element replaces another.
In double displacement: two compounds exchange ions.
What is released during a combustion reaction?
energy in the form of light and heat
Define single displacement
one element replaces another
Define double displacement
two compounds exchange ions
Combustion reactionsubstance combines with oxygen releasing energy in the form of light and heat.List three requirements for a correctly written chemical equation1. Must correctly represent the elements 2. Correct formula for the given reactants and products. 3. Must satisfy the law of conservation of mass.How are most decomposition reactions initiated?electricity or heatA substance is decomposed by an electric current.
