Question

balance the equation cabr₂ + mg(no₃)₂ → ca(no₃)₂ + mgbr₂

Explanation:

Step1: Count atoms

Count the number of each atom on both sides.
Left side: \(Ca = 1\), \(Br = 2\), \(Mg = 1\), \(N = 2\), \(O = 6\).
Right side: \(Ca = 1\), \(Br = 2\), \(Mg = 1\), \(N = 2\), \(O = 6\).

Step2: Check coefficients

Since the number of each atom is the same on both sides already.

Answer:

\(1\) \(CaBr_{2}+1\) \(Mg(NO_{3})_{2}\to1\) \(Ca(NO_{3})_{2}+1\) \(MgBr_{2}\)
