How often do you need answers to your chemistry questions? Students face difficulties over and over again when solving their chemistry problems. One solution is to get answers to chemistry questions online. There are few resources that offer chemistry answers for free, and sometimes it takes hours to find an answer to the exact chemistry question you have. Some students need AP chemistry free response answers, some search for chemistry quiz answers or even exam review answers, while others have a hard time answering their chemistry worksheets or homework assignments. Chances are that someone has already asked for a solution to your chemistry problem, or at least to a similar one, and you will be able to view the answer online. However, more often than not, students realize that the answer to this particular chemistry question is nowhere to be found. We offer the perfect solution to your struggle with chemistry. If you have a problem in any branch of chemistry, including General, Organic, Inorganic, Analytical, Physical and Macromolecular Chemistry, and Biochemistry, our experts will gladly offer their professional help. Ask your question here and get chemistry answers quickly and to the point. If you need a solution to more advanced problems, such as AP chemistry free response questions, order now, and our chemistry experts will help you for a reasonable price.

I could not find too much information in my book or the internet besides the basics (chemical formula, physical or chemical characteristics, etc.), but I did find what it can be used in. For example, fertilizer, feed additives for livestock, nutrient flavor enhancer, pharmaceuticals, leather and fur production, coloring fabrics, fermentation in beer, paper production, sewage treatment, cosmetics, but nothing about how or why chemistry labs would use it. What is its purpose?
Each time I tried to look it up other products that sounded similar but not the same appeared such as MgSO4⋅H2O or manganese sulfate, manganous sulfate etc.
19. What should be reported as the best estimate of the Br content of the unknown sample?
All the CaCO3 reacts, releasing carbon dioxide gas, and leaving a clear solution.
35.00 mL of the solution is pipetted into another flask.
28.8 mL of 0.0509 M NaOH is required to titrate the HCl remaining in this 35.00-mL portion.
What was the original mass of CaCO3 in the piece of chalk?
a. Calculate the theoretical yield of acetylsalicylic acid (molar mass = 180.2 g/mol) for this synthesis.
b. After completing the Experimental Procedure, a mass of 1.78 g of acetylsalicylic acid was recovered. What is the experimental yield for its synthesis? Express the yield with the correct number of significant figures.
2. Recrystallizing the aspirin removes some (or all) of the impurities in the sample. Explain how the recrystallization process performs this function.
