|
What are 3 factors that affect the rate of a chemical reaction
|
Surface area, temperature, strength/concentration
|
|
|
Defina a catalyst
|
something that speeds up reactions but doesnt take part in them. Usually lower the activation energy of reaction

Decomp 1.
Binary compounds break into elements Synthesis 1. Elements produce binarys Decomp 2. Carbonates (x(metallic)CO3) break into CO2 + X(+ ion)O Synthesis 2. CO2 + XO produce carbonates (XCO3) Decomp 3. Chlorates (X(+ ion, metallic)CO3) break into XCl + O2 Synthesis 3. XCl + O2 produces chlorates (XClO3) Decomp 4. Bases (X(metallic ion)OH) break into H2O + XO(metallic oxide) Synthesis 4. H20 + XO(metallic oxide) produce bases (XOH) Decomp 5. Acids break into H2) + non metallic oxide Synthesis 5. H2O and non metal oxides produce acids |

Define a chemical equation
|
an expression that describes a chemical reaction using chemical formulas and other symbols
|
|
|
Define an element
|
matter in which all atoms are alike. Cannot be broken down any further and retain its original properties
|
|
|
Define a compound
|
matter that is a combination of 2+ different atoms that are chemically combines, can be chemically broken down into elements
|
|
|
Define a mixture
|
a material made up of 2+ substances which are not chemically combined, can be seperated by physical means
|
|
|
In the single replacement lab what was the Blue? Brown?
|
Blue-Copper (Cu) ions
Brown- Copper (Cu) as an element |
