Which of the following best describes a double replacement reaction?

Answer 1

Atoms in one compound switch places with atoms in another compound.

Answer 2

A double replacment is a way of forming a new homogenous mixture. Generally double-replacement reactions involve the exchange of positive ions between two reacting compounds. Typically the compounds are in aqueous solution and are often characterized by the production of a precipitate. Explained: When dealing with two ionic compounds dissolved in water to form a homogenous mixture, there are two possiblities when they are mixed togeather. *They form a new homogenous mixture *A chemical reaction will occur,

Answer 3

It is a reaction between two compounds such that each exchanges radicals with other.

In this reaction one of the compounds formed is a precipitate which settles down at the

bottom of the cotton.

Example:-

Na2SO4 + BaCl2 -----> 2NaCl + BaSO4(s)

In this reaction, BaSO4 is a precipitate which settles down at the bottom and is insoluble in NaCl solution

Answer 4

A double replacement reaction is a chemical reaction where two compounds swap ions to form two new compounds. This typically occurs when the cations and anions of two ionic compounds switch partners. Double replacement reactions are also known as metathesis reactions.

Answer 5

A double replacement reaction involve change of bonds between two reactants as in this model:
A-B + C-D = A-C + B-D.
