When 14.0ml of HCl of unknown concentration (but less than that of the base) are reacted with 15 ml of 3.218M NaOH, 2.01KJ of heat are released. What is the molarity of the HCl solution
Give structural formulas( condensedor bond-line)for all of the different alkenes that can be hydrogenated with H2/pt to produce 3-methylheptane.
Standard reduction potentials are given on the next page. (a) Draw a diagram of the electrochemical cell, labeling all electrodes and solutions. (b) What is the pH in the Pt | H+ | H2 half-cell (c) What is the value of the equilibrium constant for..
Calculate the molarity of a solution made by adding 22.1 mL of concentrated ammonia (28.0 % by mass, density 0.880 g/mL) to some water in a volumetric flask, then adding water to the mark to make exactly 500 mL of solution.

A sample of phosgene is collected in a 250 mL flask at STP. How many moles are present in the sample of phosgene
how could you improve the resolution better separation of chlorophyll a and b? would this make the experiment take a
Why are the products attached to C3 of 1,4 pentadiene more acidic than the methyl hydrogen atoms of propene? Maybe you can help me with this one. Are the C3 atoms more acidic because there is more s character involved with the atoms and as the s ch..
