Based on the chemistry of an ion-exchange chromotography describe how you will calculate Mpc for your water samples.
A gaseous reaction occurs at a constant pressure of 50.0 atm and releases 73.4 kj of heat. Before the reaction, the volume of the system was 7.40L .
what determines the order in which the component elements of binary compounds are written?
Draw the skeletal structure of the major organic product produced when 2-methylpropanoyl chloride reacts with 3-methylbutanoic acid
Some alloys of early and late transition metals (e.g., ZrPt3) have much higher enthalpies of vaporization (per metal atom) than either of the pure metals
Consider the solution reaction AlCl3 + 3AgNO3 -> 3AgCl + Al(NO3)3. What volume of 0.100 M AlCl3 will exactly react with 55.0 mL of 0.162 M AgNO3?
Strontium carbonate decomposes upon heating to strontium oxide and carbon dioxide. Calculate the number of g of carbon dioxide produced by heating 10.7 g of strontium.
What is the equilibrium concentration of I2, Br2, and IBr? If you could show each step you do to solve for x that would be great.
I dissolved .5 grams of mustard in 3 mL of distilled water. I was asked to determine the mass percentage of acetic acid in mustard, so I added 2.5 mL of NaOH to turn the mustard solution red.
For each pair of substances below, which one will have the higher molar entropy. Justify each choice with a brief explanation. Which substance has greater molar entropy. Why is its entropy greater
A student weighed 0.0961 g of calcium carbonate (FW: 100.08 g/mol) into a 100-mL volumetric flask, dissolved the powder using nitric acid, and diluted to the mark with 0.2% nitric acid.
