What would be the effect of increasing the temperature on the following reaction? C2H2(g) + H2O(g) <=> CH3CHO(g) DHrxn = -15 1 kJ 1. [CH3CHO] would increase 2. [CH3CHO] would decrease 3. [CH3CHO] would stay the same
Calculate the concentrations of H2SO3, HSO3-, SO32-, H3O+ and OH- in a 0.025M H2SO3. The pH is 1.88 and the Ka1= 1.5 x 10-2 and Ka2 = 6.3 x 10-8.
For reaction a+ b = c the colorless reactants produce deep red complex. Heating makes the color dissapear. Once cooled the deep red color retuns
A direct current was passed through a solution containing alanine, Match the behavior with correct amino acid. The isoelectric point of histidine is 10.0.
maleic anhydride gives a compound A that undergoes acid-catalyzed dehydration to give 3,6-dimethylphthalic anhydride.
oleci acid has following compostions : 76.54%C, 12.13%H, 11.33% O. If the experimental molar mass is 282.g/mol, what is the molecular formula of oleic acid?
Acid-catalyzed dehydration of secondary and tertiary alcohols proceeds through an E1 mechanism. The first step is the protonation of the alcohol oxygen to form an oxonium ion.
In trans-1,2-dibenzoylethylene, even though the conjugated C=O group frequency coincides directly with the expected C=C stretching fequency, we would not have expected to observe the late stretching mode in the infrared spectum. Why?
Consider the following standard reduction potentials in acid solution: Cr3+ + 3e- ? Cr Eo = -0.74 V, Co2 + 2e- ? Co Eo = -0.28 V, MnO4 + 8H+ + 5e- ? Mn2+ + 4H2 Eo = +1.51 V
