Explain the order of elution you would observe while performing gas chromatography during an elimination/dehydration process on 2-butanol. What property of the product molecules seems to be the most important in determining the relative retention times?
3.00×10-3 mol of HBr is dissolved in water to make 17.0 L of solution. What is the concentration of hydroxide ions, OH-, in this solution?
which element has the greatest density at STP? and why?
water as a solvent for TLC of amino acids have opposed to a 90:7:3 acetate/water/propanioc acid?
The mass of purified sample of impure benzoic acid was .630g. How would I find the percentage recovery of my impure benzoic acid? And are the numbers I got in the lab reasonably correct?
How would you change the reaction conditions of acid-catalyzed esterification to favor ester hydrolysis rather than ester formation
identify the type of reaction..Barium chloride + sulfuric acid ---> Barium sulfate (s) + hyrdochloric acid
Show that the ammonium ion NH4+, 1ppb(mole fraction) is equivalent to 0.56 ppb (mass fraction) or .74 ugm-3 at T=298 and 1 atm. Start by solving for mass concentration Note that mass fraction is related to mole fraction as
Write a balanced chemical equation for this reaction when Ferrophosphorus reacts with pyrite making iron (ll) sulfide and a compound that is
What volume of a 0.110 M NH4I solution is required to react with 923 mL of a 0.480 M Pb(NO3)2 solution? b. How many moles of PbI2 are formed from this reaction?
Confirm that the z-component of orbital angular momentum is a basis for an irreducible representation of A2 symmetry in C3v.
What is the pH of the formic acid solution before you begin titrating? b. What is the pH after 50.0 mL of the potassium hydroxide solution has been added?
The book wants to know what the ground-state electron configuration should be for Ag+. I understand that if you have a positive ion, that it is losing an electron, so the ground state would reflect Palladium.
