Draw the major organic substitution product(s) for (2R,3S)-2-bromo-3-methylpentane reacting with the given nucleophile. Indicate the stereochemistry, including H\'s, at each stereogenic center. Omit any byproducts.
Indicate the solubility of the following solutes in 100 g of water
A sample of vanadium haveing 5.67 grams of mass upon heating combined with oxegen of 4.45gramsto make vanadium oxide. Determine the emperical formula for this compound?
The enthalpies of formation of oxalic acid in the solid and aqueous phases are -826.8 and -818.8 kJ/mol, respectively. The heat capacity of water is 4.184 J/g*K. Ignore the heat capacity of oxalic acid.
The Haber process is utilized to synthesize ammonia from hydrogen and nitrogen. How much hydrogen is required to produce 42.8 kg of ammonia. A 2.0 L vessel is filled with 7.3´ 10-4 mol hydrogen and 6.8´ 10-4 mol oxygen. Explain how much water can be..
Clausthalite is a mineral composed of lead selenide (PbSe). The mineral adopts a NaCl-type structure. The density of PbSe at 25C is 8.27g/cm^3. Calculate the length of an edge of the PbSe unit cell in Angstroms.
Hydrogen chloride gas is more soluble in water as compared to how soluble propane gas is in water, even though hcl (g) has a lower boiling point. Explain the difference between the solubility of both compounds.
What is the triple point of material X. Consider melting 3.00 moles of material X at 1.00 atm. Assuming that the melting co-existence curve is a straight line, what is X's normal melting temperature
