Question

CrI3 + Cl2 = CrCl3 + I2 is this is this combination reaction, decomposition reaction, single replacement, double replacement, or combustion?

Answer 1

A single-displacement reaction, also called single-replacement reaction, is a
type of oxidation-reduction chemical reaction when an element or ion moves out
of one compound and into another. One element (Cl) is replaced by another (I) in
a compound(CrI3).)
CrI3 + Cl2 = CrCl3 + I2
