If C4H9OH (n-butanol) burns in air to produce CO2 and water, explain how many moles of oxygen's are required for the complete consumption of one mole of n-butanol?
Draw the Lewis Structure for the ClF2+ion and AlF4-. For each ion, what are its electron-pair and molecular geometries? What orbitals on Cl and F overlap to form bonds between these elements
In a proton nmr spectrum a methylene peak appeared at delta = 2.1 ppm when a simple 60 MHz spectrometer was used. At what frequency would this peak appear if the scale were instead given in Hertz
Propose a neutral structure for each compound that is consistent with the data. Note that the absolute stereochemical configurations of chiral substances cannot be determined from the data. Arbitrarily draw a configuration for an enantiomer (and b..
What is the central atom for NH3, how many bonds are formed, what's the polarity and what's the direction of electronegativity
How many grams of C6H14 are needed to heat 1.00 kg of water from 29.5 degrees celsius to 77.5 degrees celsius. Assume that all of the heat released during the combustion is used to heat the water.
If a 484 mL sample of gas at 232 °C is allowed to expand (at constant pressure) to a volume of 494 mL, what will be the new temperature (in °C).
The experimenter at this time finds that the vessel and it contents weigh 10.5 g more than the vessel full of ethanol only. The density of the ethanol is .789g/cm^3. Explain what is the density of the object
what is the molarity of each ion in a solution prepared by dissolving 0.550 g of na2so4 1.192 g of na3po4 and 0.228 g
Through what factor would one expect the intensity of carbon tetrachloride Raman lines to increase while changing the laser source wavelength from 868.8 nm to 450.3 nm
Esters can be hydrolyzed when heated with water and strong acids or bases- the reverse of Fischer esterification. However, whereas Fischer esterification is reversible, ester hydrolysis when carried out in aqueous base is not. This is because
If 29.1 mL of 0.4 M NaOH is used to reach the endpoint when titrating 20.1 mL of acetic acid, what is the concentration of the acetic acid in moles/L
Determine the molarity of Fe+3 ions and SO4-2 ions in a solution prepared by dissolving 48.05g of Fe2(SO4)3 in enough water to make 800.0mL of solution.
