Which is a feature of a single replacement reaction? substance xyz breaks down into x and yz. substance g reacts with compound xy to form gy and x. substance x burns rapidly in the presence of oxygen. substance qr and gt exchange ions with each other.

Let us understand all the reactions

a) Substance XYZ breaks down into X and YZ: this is simple decomposition reaction

b) Substance G reacts with compound XY to form GY and X.

here G is replacing X in XY so this is single replacement reaction

c) Substance X burns rapidly in the presence of oxygen.

This is combustion reaction

d) Substance QR and GT exchange ions with each other

this is double displacement reaction

Substance G reacts with compound XY to form GY and X.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.

i'm wiling to try and you : )
