What would be potential of a battery formed by perchlorate/chlorate ion pair and Fe/FE(OH)2 pair in basic solution
when .65 moles of iron metal react with 40.0 mL of a 2.5 M copper (II)chloride solution to produce copper metal and iron (III) chloride. How many moles of copper will be produced?
Draw the major and minor products generated in the reaction of 1-Bromo-3methylene-cyclopentane in methyl alcohol and heat.
Suppose you were asked to carry out an aldol condensation reaction between benzaldehyde and 5-methylhexanal, modeled after the experiment you performed with benzaldehyde and acetone.
How many grams of aqueous iron bromide will be needed to react with an excess of potassium phosphate,K3PO4,to produce 17.1 g of solid iron phosphate?
Why do solutions of iodide ion in water appear yellow when I- is oxidized to I2 by a suitable oxidizing agent, while solutions of I- in CCl4 or CHCl2 appear violet when the same oxidationis done?
the cytoplasmic concentration is 0.4 micromolar, and the extracellular concentration is 1.5 micromolar, and the membrane potential is -60 mV?
Calculate the concentration of the acetate ion (mol/L) in a solution prepared by dissolving 1.00×10-2 mol of HCl(g) in 1.00 L of 9.00×10-1 M aqueous acetic acid. Equilibrium constants may be found in an appendix to your text.
Magnesium hydroxide is only very slightly soluble in water. The reaction by which it goes into solution is: Mg(OH)_2 (s) Mg^2+ (aq) +2 OH- (aq)
Write ionic and net ionic equations for the following reactions. (Use the lowest possible coefficients. Include states-of-matter under SATP conditions in your answer.)
C.A. Yates was given a 50.0mL sample of the weak acid. The known concentration of the weak acid is .25M. After preparing a buret he delivers 25.0mL of the weak acid into a 100mL Erlenmyer flask. He then titrated this solution using a standardized ..
Find what is the initial concentration of the chlorine before dilution - unknown concentrated chlorine
Imagine a researcher allowed the paper chromatogram to develop for far longer than necessary in the mobile phase, such that the solvent front ran into the top edge of the paper and the spots continued to move.
