Question

is this chemical equation \balanced\ or \unbalanced\?
nabr + naf + cabr2
caf2 + balanced unbalanced

Explanation:

Step1: Count atoms on each side

On the left - hand side (LHS):

• For Na: 1 atom (from NaF)
• For F: 1 atom (from NaF)
• For Ca: 1 atom (from CaBr₂)
• For Br: 2 atoms (from CaBr₂)

On the right - hand side (RHS):

• For Na: 1 atom (from NaBr)
• For Br: 1 atom (from NaBr)
• For Ca: 1 atom (from CaF₂)
• For F: 2 atoms (from CaF₂)

Step2: Check balance

Since the number of Br atoms (2 on LHS vs 1 on RHS) and F atoms (1 on LHS vs 2 on RHS) are not equal on both sides of the equation.

Answer:

Unbalanced
