Question

What would the products of a double-replacement reaction between KBr and CaO be? (Remember: In double-replacement reactions, the two cations switch places and the two anions switch places.)A.KBr and CaOB.CaBr2 and K2OC.Br2O and CaK2D.CaBr and KO

Answer 1

`\begin{gathered} \text{ 2KBr }+\text{ CaO }\rightarrow\text{ K}_2O\text{ }+\text{ CaBr}_2 \\ Option\text{ B} \end{gathered}`

Step-by-step explanation

Given that;

The two reactants are KBr and CaO

Double replacement reaction is a type of chemical reaction that occur when two reactants exchange cations and anions to yield new products.

`\text{ 2KBr + CaO }\rightarrow\text{ K}_2O\text{ + CaBr}_2`

Therefore, the resulting products of the given data are K2O + CaBr2

The correct answer is option B
