Science / Chemistry / Displacement: A reaction in which a fragment of one reactant is replaced by another reactant (or by a fragent of another reactant). Displacement reactions have the same number of products as reactants, and are described by equations of the form A + BC rightarrow AB + C (single displacement) or AB + CD rightarrow AC + BD (double displacement).
Science / Chemistry / Double Displacement: A double displacement or metathesis is a reaction in which two reactants trade fragments: AB + CD = AC + BD, Most commonly, the fragments are ions, e. G. Agno3(aq) + nacl(aq) = agcl(s) + nano3(aq) MORE
Science / Marine Biology / Character Displacement: A pattern in which two species with overlapping ecological requirements differ more when they co-occur than when they do not. The difference is usually in a morphological feature related to resource e MORE
