Question

make the following follow the law of conservation of matter. ____ NaBr+____ CaF2-->____ NaF+____ CaBr2

Answer 1

2NaBr + CaF₂ ⟶ 2NaF + CaBr₂

Step-by-step explanation:

Put a 1 in front of the most complicated-looking formula (CaF₂?):

NaBr + 1CaF₂ ⟶ NaF + CaBr₂

Balance Ca: NaBr + 1CaF₂ ⟶ NaF + 1CaBr₂

Balance F: NaBr + 1CaF₂ ⟶ 2NaF + 1CaBr₂

Balance Na: 2NaBr + 1CaF₂ ⟶ 2NaF + 1CaBr₂
