Which information can you determine about a chemical reaction from a complete chemical equation

From a complete chemical equation, you can determine the reactants and products that were involved in the reaction. For each reactant and product, you will also know its physical state (like aqueous, liquid, solid or gas) before and after the reaction.

You can also determine the type of reaction that it was (like single/double displacement, neutralization, combustion, synthesis or decomposition).

In a balanced equation, you will also know how many atoms there were.

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).

the answer is barium and copper bromide
