Sorry, for returning to this forum for help again, but my teacher is not exactly the best, and I'm not the brightest student. Acid Initial Buret Reading (mL): 3.70 Acid Final Buret Reading (mL): 13.70 Base Initial Buret Reading (mL): 11.65 Base Final Buret Reading (mL): 23.55 The base, NaOH(aq), was...

Hello, it's me again! Could someone please help me with one of my analyses of my Epsom Salt lab? Here's my data table: Data and Calculation Table Part I 1. Mass of crucible and cover 22.39 g 2. Mass of crucible, cover, and hydrate 24.969 g 3. Mass of hydrate 2.579 g 4. Mass of crucible, cover, and a...

Thank you!

This is one of the problems I can't answer for this lab: 1. Heat CuSO4*5H2O 2. Add H2O to CuSO4 3. Add NH3 to CuSO4(aq) 4. Add H2SO4 to Cu(NH3)4 2+ Why can't carbonates, chlorates, or hydroxides be used in this experiment? Explain and specify what is produced when these compounds are heated. I answe...

An experiment is performed to determine the empirical formula of a copper iodide formed by direct combination of elements. A clean strip of copper metal is weighed accurately. It is suspended in a test tube containing iodine vapor generated by heating solid iodine, A white compound forms on the stri...
