A. Briefly explain how a loss of water by evaporation would affect the initial calculation of the solubility of your salt. B. Would this initial evaporation affect the calculated solubility of your salt at each subsequent experimental saturation temperature, or just the initial temperature? Explain.

Following are the solution to this question:

Explanation:

Please find the complete question in the attached file.

In point a:

When some water evaporates from its mixture, then when a thick layer is initiated, it reduces salt solubility, but sodium remains unclear throughout the solution (ppt solte).  

In point b:

Ksp is measured by calculating the mass of its solvent reduction process, decreasing salt solubility and hence decreasing Ksp.  

In point c:

From of the graph are calculated by v/s lnKsp  

(decrease) LnKsp may shift,  

So, both are decreasing

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).

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
