2HCI + Na2SO4 → 2NaCl + H2SO4 How many moles of H2SO4 are included in the reaction when H2SO4 has a mass of 12.72g?
0.33 mol
0.65 mol
0.67 mol
0.13 mol

answer: a chemical reaction

explanation:

im not wrong

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).

c) should be the answer.
