Question

balance the following the chemical equation: _na₂o + _cabr₂ → _nabr + _cao (1 point) o 2:1:1:1 o 1:2:1:1 1:1:2:1 o 1:1:1:2

Explanation:

Step1: Balance sodium atoms

On the left - hand side, there are 2 sodium atoms in $Na_2O$. On the right - hand side, there is 1 sodium atom in $NaBr$. So, we put a coefficient of 2 in front of $NaBr$: $Na_2O+CaBr_2
ightarrow2NaBr + CaO$.

Step2: Check other atoms

Calcium and oxygen atoms are already balanced on both sides. There is 1 calcium atom and 1 oxygen atom on each side.

Answer:

1:1:2:1
