How to write discussion for the experiment of identification of unknown solutions of amino acids and carbohydrates
Anthraquinone contains only carbon, hydrogen and oxygen as well as has an empirical formula of C2H4O.The freezing point of camphor is lowered by 22.3C when 1.32g anthraquinone is disolved in 11.4g camphor. Find out the molecular formula of anthraq..
What is the formal charge of any oxygen with 3 bonds?.. 2 bonds?.. And 1 bond?
The mole fraction of propane in the vapor phase is 0.67 and 0.40 in the liquid phase. Additional pure propane is added to the system and the system is brought again to equilibrium at 10 bar and 323 K. What is the effect of the propane addition on ..
Draw structural formulas for the organic product(s) formed when the following compound is heated at reflux in an excess of concentrated HI
Consider the following equilibrium process at 700°C. 2H2(g)+S2(g) 2H2S(g) Analysis shows that there are 2.50 moles of H2, 1.35 10-5 mole of S2, and 8.70 moles of H2S present in a 12.0 L flask. Calculate the equilibrium constant Kp for the reactio..
if you knew an electron transfer center in a protein had a reduction potential of -400 mv what would be the most likely
The voltage generated by the zinc concentration cell described by, Zn(s)|Zn2 (aq, 0.100 M)||Zn2 (aq, ? M)|Zn(s) is 28.0 mV at 25 °C. Calculate the concentration of the Zn2
Explain your reasoning for each by writing a balanced net ionic equation to describe its behavior in water.
Calculate the pH at the following points during the titration of 100.0 mL of 0.20 M acetic acid (Ka for acetic acid = 1.8 x 10-5) with 0.10M sodium hydroxide
A 25.0-mL solution of 0.0430 M EDTA was added to a 48.0-mL sample containing an unknown concentration of V3 . All V3 present formed a complex, leaving excess EDTA in solution. This solution was back-titrated with a 0.0440 M Ga3 solution until all ..
A solution contains 15mL 0.1 M KI, 15 mL of DI water and 5 mL o f3% H2O2. After the decomposition of H2O2 is complete, you titrate the solution with 0.1 M AgNO3. If the catalyst, I-, is not consumed in the reaction and is completely recovered, wha..
