Why ammonium oxalate is added in calcium carbonte solution?
ammonium oxalate is added to calcium carbonate because in the reaction between the two a crystal is formed that contain the Ca+2 ion. This is useful because if you have a sample of sodium carbonate with an unknown molarity you can use the oxalate to extract this calcium and determine what the molarity of the unknown solution was
A scientist suspect that a mineral sample is a carbonate. which useful for identifying the sample as a carbonate?
A sample of carbonate is acid. Acid is what identifies carbonate in science studies.
A 15.7g sample of sodium carbonate is added to a solution of acetic acid weighing 18.9 g and after reaction weighing 26.3g what is mass of carbon dioxide?
8.7g
How many moles of ammonium sulfate are in 150g sample?
150/132 equals 1.136moles
Can density of an entire solution be measured from a small sample?
Yes, because the definition of a solution is a homogenous mixture. Therefore, one part of the solution will have the sample definite properties as the entire solution.
How many moles of ammonium ions does a 22.5 gram sample of ammonium carbonate?
A 22.5 gram sample of ammonium carbonate contains 4.5 moles of ammonium ions.

How would a dry sample of sodium carbonate be obtained from a mixture of sodium carbonate and calcium carbonate?
Calcium carbonate is not soluble in water, sodium carbonate is soluble in water. Dissolve the mixture and filter: the Na2CO3 pass the filter as a solution and CaCO3 remain on the filter. Gently warm the solution to obtain crystallized sodium carbonate.
What is the purpose of dissolving unknown Fe in the acid?
The purpose is to prepare a sample solution for analysis.
