Question

Solid sodium and bromine gas are formed by the decomposition of solid sodium bromide . Write a balanced chemical equation for this reaction.

Answer 1

2NaBr(s)=2Na(s)+Br2(g)

Answer 2

Answer:
`2NaBr(s)\rightarrow 2Na(s)+Br_2(g)`

Step-by-step explanation: According to the law of conservation of mass, mass can neither be created nor be destroyed.

Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

This is an example of decomposition reaction in which energy is required to convert one reactant to two or more than two products.

`2NaBr(s)\rightarrow 2Na(s)+Br_2(g)`
