the equation from my textbook: 2k+2H2O yields 2KOH+H2 why? I thought that such reactions are when one element swaps with another but in this case, there is an extra H2

A single replacement reaction is a type of chemical reaction where one element replaces another element in a compound.
A single replacement reaction can be identified by the general form of A + BC → AC + B, where A and B are elements and BC is a compound. Additionally, a single replacement reaction typically involves a more reactive element replacing a less reactive element.
The purpose of a single replacement reaction is to produce a new compound by replacing one of the elements in a compound with a different element. This can result in a change in physical or chemical properties of the compound.
Some common examples of single replacement reactions include the reaction of iron with oxygen to form iron oxide, the reaction of zinc with hydrochloric acid to form zinc chloride, and the reaction of copper with silver nitrate to form copper nitrate and silver.
The rate of a single replacement reaction can be influenced by factors such as temperature, concentration of reactants, and the presence of catalysts. A higher temperature and higher concentration of reactants can typically result in a faster rate of reaction, while a catalyst can speed up the reaction without being consumed in the process.
