Single replacement ex: 2K + 2HCl --> 2KCl + H2
Double replacement ex: Na2SO4 + 2CaCO3 --> Na2CO3 + CaSO4
Combustion ex: H2CO3 --> H2O + CO2
Synthesis ex: 2Fe + O2 --> 2FeO

The four different types of chemical weathering are hydration, oxidation, carbonic acid action and hydrolysis. Chemical weathering is a chemical reaction that erodes certain things such as building materials and rocks.
If one knows the mole ratio of a reactant and product in a chemical reaction one can

There are various ways to categorize reactions, but broadly speaking, they can be classified into four main types: synthesis, decomposition, single displacement, and double displacement reactions. Each type of reaction involves a different rearrangement of atoms between reactants and products.
Some indicators of a chemical reaction are: - change of color - change of odor - release of a gas - change of the temperature - change of the viscosity - formation of a precipitate - change of general appearance - possible explosion - possible chemiluminiscence -formation of new compounds
the four components of fire are heat, fuel, oxygen and the sustaining chemical reaction
potential light heat and chemical
- forming a homogeneous solution- forming a precipitate by chemical reaction- sedimentation of an insoluble phase, without chemical reaction
four tyes of precipitation are rain, snow, sleet, and hail
Precipitation formsProduction of bubblesTemperature changeColor change
Four factors are:- temperature- pressure- catalysts- stirring
