Answer:
Depends since Chemical equation is not written clearly...
Explanation:
if if the comma represents an equal sign then I would assume that this would be a single replacement... however if this is all one equation I would assume it is a double replacement.
The type of chemical reaction shown in the question is a: A. Single replacement.
A chemical reaction can be defined as a chemical process involving the continuous transformation (rearrangement) of either the ionic, atomic or molecular structure of a chemical element, especially through the breakdown and formation of chemical bonds, in order to produce a new chemical compound.
In Chemistry, there are five (5) main types of chemical reaction and these include;
A single-replacement reaction is also referred to as a single-displacement reaction and it can be defined as a type of chemical reaction wherein a single (one) chemical element of the reacting chemical compound is replaced (substituted) by a similar chemical element.
Basically, a single-replacement reaction typically involves a single element ([tex]O_2[/tex]) replacing another element ([tex]Cl_6[/tex]) within a chemical compound ([tex]SeCl_6[/tex]).
[tex]SeCl_6+O_2[/tex] ----> [tex]SeO_2 + 3Cl_2[/tex]
In conclusion, the above chemical reaction is a single-replacement reaction because oxygen gas replaces the chlorine molecules in selenium hexachloride.
