Double replacement
Double-replacement
This kind of chemical reaction is usually called "displacement" and sometimes "substitution".
The general form for a double-displacement reaction is AB + CD -> AD + CB, where two compounds swap anions or cations to form two new compounds.
The general equation for an endothermic double replacement reaction is: AB + CD → AD + CB + heat absorbed. In this reaction, the reactants AB and CD exchange ions to form the products AD and CB, with the absorption of heat from the surroundings.
This kind of reaction is called a double replacement or double displacement reaction, and has the pattern AB + CD --> AD + CB.
AB + CD ==> AD + CB
Synthesis - A + B = AB Decomposition - AB = A + B Single Replacement - A + BC = B + AC Double Replacement - AB + CD = AD + CB Combustion - either a synthesis, decomposition, or single replacement reaction. It combines with oxygen.
other name for an exchange reaction but metathesis reaction. This reaction usually occurs in hydrolysis and is AB+CD=AD+CB
When many were taught chemistry in the 1970s this was called a double decomposition reaction. It is now called a salt metathesis reaction and also double displacement reaction. There are examples and more information at the related link.
Ab+cd > ad+cb. A and c are the metals or the positive ion
im pretty sure it depends on the type of reaction wether its a synthesis (a+B=ab), single displacment (a+bc=b+ac) or double displacment(ab+cd=ad+bc).
Single replacement
