2) Chemical analyses of silicate minerals are given as weight percent oxides, to ensure that charges of cations and anions are balanced. It’s important to be able to interconvert mineral chemical formula and chemical analyses (see Klein pp. 99-104). Analysis of an olivine yields (all as weight percent): 36.63% SiO2, 30.96% MgO, 32.41% FeO; express this composition in terms of mole % forsterite (i.e., Fox, find x). You will need to calculate the formula weights of FeO and MgO. Please...

A) Determine the Solubility product of calcite at 25c and 40c. At which temperature is calcite more soluble? B)A sample of water has a calcium ion activity (aca2+) of 10^-3.04 and a carbonate ion activity of 10^-5.56. is this water sample in equlibrium with calcite?if not is calcite dissolving or precipitating? (assume STP< use information from A)

In this assignment, you will identify some minerals. The
ability to identify minerals is one of the most fundamental
geological skills. It is an essential skill in identifying rocks,
for one must first identify the minerals within a rock before the
rock itself can be identified. Only after minerals and rocks have
been identified can their origin, classification, and alteration be
adequately understood. The ability for a geologist to identify
minerals by using the simplest tools is often a necessity,...
