A buffer is made up of 0.1 M 15.0 mL of HC2H3O2 and 15.0 mL of 0.1 M N a C2H3O2. The solution is diluted with 30.0 mL of water. Five drops of 0.1 M N a O H is added. What was observed to happen to the pH and why?

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).

it would be a gas formation
