Singe Replacement Reaction
|
is a reaction in which one element takes the place of another element in a compound.
In a single-replacement reaction, both the reactants and the products are an element and a compound. |
|
Net ionic equation
|
Net ionic equations show only those particles directly involved in the reaction and is balanced with respect to mass and charge.
|
|
Coefficient
|
a small whole number that appears in front of a formula in a balanced chemical equation
|
|
Spectator ion
|
are ions that stay in solution.
(are the ions that do not form precipitants) |
|
Catalyst
|
is a substance that speeds up the reaction but is not used up in the reaction
A catalyst is neither a reactant nor a product, so its formula is written above the arrow in a chemical equation. |
|
Reactants
|
are substances that undergo a chemical change
|
|
Products
|
new substances formed from a chemical change
|
|
Synthesis or Combination Reaction
+ after the reaction there is always... |
is a reaction in which two or more substances combine to form a single product
-there is always a single product. |
|
Double replacement reaction
|
a chemical change that involves an exchange of positive ions between two compounds
-cations replace cations and the solid/precipitant can tell you which elements/ions will be spectator ions w/the rules of solubility |
|
Combustion
|
a chemical change in which an element or a compound reacts with oxygen, often producing energy in the form of heat and light
|
|
decomposition
|
a chemical change in which a single compound is broken down into two or more simpler products
|
|
The complete combustion of a hydrocarbon produces...
|
carbon dioxide and water.
|
|
A skeleton equation
|
is a chemical equation that does not indicate the relative amounts of reactants and products
|
|
Balanced equation
|
a chemical equation in which mass is conserved; each side of the equation has the same number of atoms of each element
|
|
Pt
--> |
A formula written above or below the yields sign indicates its use as a catalyst
|
|
Δ
--> or heat --> |
Indicates that heat is supplied to the reaction
|
|
What determines whether metal will replace another metal from a compound in a single- replacement reaction?
|
the levels of reactivity the metals hold determine whether a metal will replace another metal in a chemical reaction. A metal must be more reactive then the metal it is replacing/displacing otherwise that reaction can't take place.
