3. Which type of reaction is described by the following equation? CS + H2O > CSOH + H2

A)synthesis
B)combustion
C)decomposition
D)single-replacement

CS + H2O > CSOH + H2 is described by a :

D) Single-Replacement reaction

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.

+2

Explanation:

The nitrate ion is a radical with an overall charge of -1. To get the oxidation number of lead, add up all the oxidation numbers and equate to zero. Therefore the oxidation state of lead is +2.
