CS + H2O -----> CSOH + H2 is described by a :
D) Single-Replacement reaction
Step-by-step explanation:
- A single replacement reaction occurs when one element replaces another element in one compound. 
 - This type of reaction is represented by: A + BC → B + AC. A double replacement reaction occurs when two ionic compounds exchange ions, producing two new ionic compounds.
 - A metal only replaces a metal, and a nonmetal only replaces a nonmetal. 
 - A single-replacement reaction replaces one element for another in a compound. The periodic table or an activity series can help predict whether single-replacement reactions occur. 
 - A double-replacement reaction exchanges the cations (or the anions) of two ionic compounds.
 - A real-world example of a single replacement reaction is the formation of rust.
