What type of chemical reaction is occurring when chlorine gas is bubbled through a calcium bromide solution, resulting in the solution turning brown?
gpt
A Single-Replacement reaction.
Explanation: In a single-replacement reaction, one element displaces another element from a compound. In this case, chlorine gas (Cl2) reacts with calcium bromide (CaBr2) to displace bromine (Br2) from the solution, resulting in the formation of calcium chloride (CaCl2) and bromine gas, which is brown in color.
