What is the balanced chemical equation for the reaction that takes place between bromine and sodium iodide?

Br₂ + 2NaI →  2NaBr + I₂

Explanation:

This is the reaction:

Br₂ + 2NaI →  2NaBr + I₂

It's a sort of redox, where the bromime is reducted to bromide and iodide is oxidated to iodine.

Br₂ + 2e⁻ → 2Br⁻

2I⁻ → I₂ + 2e⁻

im not exactly sure but i think its b!

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
