What is the general equation for the four types of chemical reactions.?

Question

I missed chemistry for a week Please give me a site or the answer

Answer 1

Every chemical reaction can be placed into one of 4 general categories:

1- Synthesis
A synthesis reaction is when two or more simple compounds combine to form a more complicated one. These reactions come in the general form of:
A + B ---> AB

2- Decomposition
A decomposition reaction is the opposite of a synthesis reaction - a complex molecule breaks down to make simpler ones. These reactions come in the general form:
AB ---> A + B

3- Single Displacement
This is when one element trades places with another element in a compound. These reactions come in the general form of:
A + BC ---> AC + B

4- Double Displacement
This is when the anions and cations of two different molecules switch places, forming two entirely different compounds. These reactions are in the general form:
AB + CD ---> AD + CB

Answer 2

All chemical reactions might want to be positioned into one in each and every of six diverse sorts. right here they are, in no particular order: a million) Combustion: A combustion reaction is at the same time as oxygen combines with yet another compound to variety water and carbon dioxide. those reactions are exothermic, meaning they produce warmth. An get mutually of one of those reaction is the burning of napthalene: C10H8 + 12 O2 ---> 10 CO2 + 4 H2O 2) Synthesis: A synthesis reaction is at the same time as 2 or extra easy compounds combine to variety a extra complicated one. those reactions are available the overall variety of: A + B ---> AB One get mutually of a synthesis reaction is the mixture of iron and sulfur to variety iron (II) sulfide: 8 Fe + S8 ---> 8 FeS 3) Decomposition: A decomposition reaction is the option of a synthesis reaction - a complicated molecule breaks right down to make less difficult ones. those reactions are available the overall variety: AB ---> A + B One get mutually of a decomposition reaction is the electrolysis of water to make oxygen and hydrogen gas: 2 H2O ---> 2 H2 + O2 4) unmarried displacement: it is at the same time as one aspect trades places with yet another aspect in a compound. those reactions are available the overall variety of: A + BC ---> AC + B One get mutually of a unmarried displacement reaction is at the same time as magnesium replaces hydrogen in water to make magnesium hydroxide and hydrogen gas: Mg + 2 H2O ---> Mg(OH)2 + H2 5) Double displacement: it is at the same time as the anions and cations of two diverse molecules swap places, forming 2 completely diverse compounds. those reactions are in the overall variety: AB + CD ---> ad + CB One get mutually of a double displacement reaction is the reaction of lead (II) nitrate with potassium iodide to variety lead (II) iodide and potassium nitrate: Pb(NO3)2 + 2 KI ---> PbI2 + 2 KNO3 6) Acid-base: it is a particular type of double displacement reaction that takes position at the same time as an acid and base react with one yet another. The H+ ion in the acid reacts with the OH- ion in the bottom, causing the formation of water. commonly, the made from this reaction is a few ionic salt and water: HA + BOH ---> H2O + BA One get mutually of an acid-base reaction is the reaction of hydrobromic acid (HBr) with sodium hydroxide: HBr + NaOH ---> NaBr + H2O

Answer 4

aA + bB = cC + dD
Reactions are oxidation, addition, substitution, and elimination
