The half-cell, Tl | Tl+(1 mol L?1), is connected to a Pt | H+ | H2(1 atm) half-cell in which the concentration of H+ is unknown. The measured cell voltage is 0.0841 V and the Pt | H2 | H+ half-cell is the cathode. 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 the reaction occurring in this cell
To better understand why, scientists synthesized artificial protein mimics that were linked by ester bonds instead of the amide functionality ( the R-group side chains all remained the same). They found that these mimics did not form highly organi..
if the tank is heated, what is the maximum pressure that will be attained in the tank before the plug will melt and release gas?

write the complete mechanism for the initiation and propagation steps using free radical notation for free radical notation mono-chlorination reaction of the alkane: 2, 4 - dimethylpentane.
One of the most common causes of inaccurate melting points is too rapid heating of the melting point apparatus near Tmelt. Under these circumstances, how will the observed melting point compare to the true melting point
