Chemical reactions
Displacement reactions
A +BC --> AC + B; In this reaction, one element displaces another in a compound.
Combustion reactions
A type of redox reaction. Characterized by the reaction of a substance with O2 to form one or more oxygen-containing compounds, often including water(water formed can be gaseous or liquid depending on the reaction conditions.. It's exothermic, emitting heat.
Double-Displacement reactions
AB + CD --> AD + CB; In this reaction, two elements or groups of elements in two different compounds exchange places to form two new compounds.
Decomposition reactions
AB --> A + B; in this reaction , a complex substance decomposes to form simpler substances.
Synthesis/Combinations Reactions
In this reaction, Simpler substances combine to form more complex substances. A + B --> AB
Classifying 5 chemical reactions?
Precipitation, Acid-Base, Gas Evolution, Oxidation-reduction, combustion
Oxidation-reduction reactions
Reactions involving the transfer of elections. is also called a redox reaction and is classified as a redox reaction if it met requirements: 1. a substance reacts with elemental oxygen 2. a metal reacts with a nonmetal 3. more generally, one substance transfers electrons to another substance.
4 Classifying chemical reactions by what atoms do
There's an alternative way to classify chemical reactions is by what atoms or groups of atoms do during the reaction. There are...Synthesis or combination, decomposition, displacement, double displacement
Gas evolution reaction
reactions that evolve a gas. also can be acid-base reactions. 1. reacts between cation and anion too. 2. form an intermediate product that then decomposes into a gas.
Precipitation reactions
reactions that form a solid upon mixing two aqueous. 1. only insoluble compounds form precipitates. 2. if potentially insoluble products are both solid, then no reactions offcurs. 3. if one or both of the potentially insoluble products are indeed insoluble, precipitates.
Acid-Base(neutralization) reactions
reactions that form water upon mixing of an acid and a base. 1. reacts between cation and anion. 2. acid is characterized by sour taste, ability to dissolve metals, and tendency to form H+ ions in solutions. 3. base is characterized by bitter taste, slippery feel, and its tendency to form OH- in solution.
