Question

Question 3: When a sample of solid silver bromide decomposes over time it will form solid silver and bromine gas. This decomposition does reach completion and all reactant transitions to products.
A. Write the full reaction with the correct physical states and balance the equation with all required work/steps or explanation
2-5 sentences please

Answer 1

1) The balanced chemical reaction for the decomposition of solid silver bromide is:

2 AgBr(s) -> 2 Ag(s) + Br2(g)

2) First, count the number of atoms of each element on both sides of the equation. There are 2 silver atoms, 2 bromine atoms, and 2 bromide ions on the reactant side, and 2 silver atoms and 2 bromine atoms on the product side.

3) To balance the equation, we need to adjust the coefficients in front of the reactant and product. Therefore, the balanced equation for the decomposition of solid silver bromide is 2 AgBr(s) -> 2 Ag(s) + Br2(g).
