7) A high-altitude balloon travels from an altitude of 18 km to an altitude of 30 km above sea level. On it's ascension, the temperature of the gas changes from - 62 °C to -38 °C. What
happened to the pressure of the gas inside the balloon as the balloon ascended? Explain in
terms of the frequency and force of collisions against the walls of the balloon.

if the concentration of products is decreased, the equilibrium will shift toward the products). add an inert gas (one that is not involved in the reaction) to the constant-volume reaction mixture: this will increase the total pressure of the system, but will have no effect on the equilibrium condition.

explanation:

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 option a.
