1. Suggest a suitable series of reactions for carrying out each of the following synthetic transformations:
The saturated calomel electrode (S.C.E.) is one commonly used reference electrode, with a potential of 0.242 V versus the S.H.E. Using a table of standard reductions, determine what the potential of each reduction below would be versus the S.C.E.
In the reaction between butanal and propanal, two different aldehydes are used and thus four different aldol addition products can be formed (which makes this an undesirable route for making aldols). Depict the skeletal structure of the aldol addi..
Depict a Lewis structure for the most significant resonance form of each ion showing formal charges and oxidation numbers of the atoms (a) AsO43- (b) ClO-2 Explain what are the oxidation numbers for As and O in ASO43-
A sample of vinegar (dilute acetic acid) weighing 5.056 g is titrated with 30.25 mL of 0.1022 M NaOH. What is the weight percent of acetic acid (CH3COOH) in the sample
calculate the molality, molarity, and mol fraction of HF in a solution made by dissolving 5.0g of HF in 250g of water
The specific heat of liquid ethanol, C2H5OH(l), is 2.46 J/g·°C and the heat of vaporization is 39.3 kJ/mol. The boiling point of ethanol is 78.3 °C. The molecular weight of ethanol 46 g/mol.
The rate of the subsequent reaction is 0.720 M/s. Define what is the relative rate of change of each species in the reaction. A + 4B yields 2C
In the blood of an adult human, there are approximately 2.69e13 red blood cells with a total of 2.90 g of iron. On the average, how many iron atoms are present in each red blood cell. (molar mass (Fe) = 55.85 g)
a concentration of 8.00 x 102 ppm by volume of carbon monoxide is considered lethal to humans. calculate the volume in
Calculate the molar solubility of PbCl2 in a 0.20 M NaCl solution. The Ksp of PbCl2 = 1.7 x 10-5. Can any assumptions be made to simplify this calculation
D-maltose is a disaccharide and D means the OH on the second to last carbon to the bottom is on the Right and L means left how do we draw a structure of D-maltose or alpa-D-maltose
Calculate the pH of a buffer solution that contains 0.25 M benzoic acid (C6H5CO2H) and 0.15 M sodium benzoate (C6H5COONa). [Ka = 6.5 ? 10-5 for benzoic acid]
