Which of the following is a balanced chemical equation for the synthesis of NaBr from Na and Br2? A. 2Na + Br2 --> 2NaBr B. NaBr --> Na + Br2 C. 2NaBr --> 2Na + Br 2 D. 2Na + Br2 → NaBr
Answer:
A) 2Na + \(Br_{2}\) = 2NaBr
Explanation:
As the problem says that you should find the balanced chemical equation for the synthesis of NaBr from Na and \(Br_{2}\), the reactants are Na and \(Br_{2}\) and the product is NaBr, so it can be writen as:
Na + \(Br_{2}\) = NaBr
Then you shoud balance the equation, it means that you should have the same number of each element in each part of the equation, so if you put a number 2 for the NaBr and the Na, the equation will be balanced:
2Na + \(Br_{2}\) = 2NaBr
