|
What elements are the naturally occuring Diatomic Molecules? |
H2, N2, O2, Cl2, Br2, I2 |
|
|
How many diatomic molecule altogether? |
7 elements |
|
|
lists of active metals |
Li>K>Ba>Sr>Ca>Na
|
|
|
Combination reation |
When two or more reatants combine to form a single product
|
|
|
A + Z ------> AZ |
combination reaction |
|
|
decomposition reation |
when a single compound breaks down into two or more simpler substances, often with a use of catalyst to speed up the reaction |
|
|
AZ ------> A + Z |
decomposition reaction |
|
|
single replacement reaction |
when one element displaces another. For this to occur, a more active element that is higher in the activity series displaces an element that is lower in the series. |
|
|
A + BZ ----> AZ + B |
single- replacement reaction |
|
|
double-replacement reation |
when two substances in aqueous solution switch partners; that is, an anion of ome substances exchanges with another. Usually one of the substance is called a precipitate. |
|
|
AX + BZ ----> AZ +BX |
double-replacement reaction |
|
|
neutralization reaction |
when an acid and a base react to form a salt and water. This is a special type of double-replacement reaction. |
|
|
HX +BOH ---> BX + HOH |
neutralization reaction |
|
|
-------> |
produces, yields (separates the reactants from the product) |
|
|
+ |
reacts with, added to ( separates two or more reactants or products) |
|
|
NR |
no reaction |
|
|
(s) |
solid substance or precipitant |
|
|
(aq) |
aqueous solution |
|
|
(g) |
gaseous substance |
|
|
(l) |
liquid substance |
|
|
what are the 4 evidence for a chemical reaction? |
1) a gas is released 2) a precipitate is produced 3) a permanent color change 4) an energy change such as heat or light being given off |
