methane burns in oxygen to produce carbon dioxide and water. which of the following represents
correct chemical formulas?
reliminary, unbalanced equation with the
a. ch4 + o2 - co2 + h20
b. ch4 + co2 + o2 + h2o
c. co2 + h20 - ch4 + o2
d. ch4 - o2 + co2 + h20

A

Explanation:

CH4+O2-CO2+ H20

that mean methane has burn in oxygen to produce CO2

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).
