Question

predict the product(s) of the double replacement reaction below: calcium bromide + sodium oxide ----> 2 nabr + o₂ cana₂ + br₂o canabro cao + 2 nabr

Explanation:

Step1: Understand double - replacement reaction

In a double - replacement reaction, the general form is \(AB+CD
ightarrow AD + CB\).

Step2: Write the chemical formulas

Calcium bromide is \(CaBr_{2}\), sodium oxide is \(Na_{2}O\).

Step3: Exchange ions

The \(Ca^{2 +}\) from \(CaBr_{2}\) combines with \(O^{2 -}\) from \(Na_{2}O\) to form \(CaO\), and the \(Na^{+}\) from \(Na_{2}O\) combines with \(Br^{-}\) from \(CaBr_{2}\) to form \(NaBr\).
The balanced chemical equation is \(CaBr_{2}+Na_{2}O
ightarrow CaO + 2NaBr\)

Answer:

Calcium oxide (\(CaO\)) and sodium bromide (\(NaBr\))
