The total bonding energy for the products of a reaction is 1230 kj/mol and the bonding energy of the reactants is 565 kj/mol. calculate the change in enthalpy, and classify the reaction as endothermig or exothermic. -665 kj/mol, endothermic 665 kj/mol, exothermic -665 kj/mol, exothermic 665 kj/mol, endothermic

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).

catya your not at all which answer i've seen you do this on another question!
