1 A 5.00 L air sample at a temperature of -10.0oC has a pressure of 107 kPa. What will be the new pressure if the temperature is raised to 95oC and the volume expands to 8.00L? Show your work! 2 What pressure will be exerted by 0.450g of H2 at 78oC if it is contained in a 0.750 L vessel?

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).
