What spectral features including mass spectra, IR spectra, proton spectra and carbon spectra allow you to differeniate the product (methyl benzoate) from the starting material (benzoic acid)?
What is the concentration of [Cl?] in a solution of 10 mL of 12 M HCl when 6 mL of water is added
A chemist produces 460 mL of oxygen gas at - 43 °C and constant pressure. To what Celsius temperature must the oxygen be warmed in order for it to have a volume of 600 mL?
When a glow stick is placed in a freezer, its chemiluminescence lasts a significant time longer. How might this come about?
A 53.5 g of an ideal gas of molecular weight = 10.5 g/mol is confined at a pressure of 50 kPa. The density of the gas is 0.164 g/L. Compute the temperature of the gas in degrees Celsius.
How many milliliters of 0.200 M NaOH are needed to neutralize 100. mL of 0.100 M HCl
Solids generally expand as the temperature increases. Such an expansion results from an increase in the bond length between adjacent atoms as the vibrational amplitude increases.
Suppose that 0.650mol of methane, CH4(g), is reacted with 0.800mol of fluorine, F2(g), forming CF4(g) and HF(g) as sole products. Assuming that the reaction occurs at constant pressure, how much heat is released
Calculate the cell potential for the following reaction as written at 59 °C, given that [Zn2 ] = 0.874 M and [Sn2 ] = 0.0170 M. Standard reduction potentials can be found here.
a corrosion technologist pipetted a 100 ml hard water sample and titrated it with 37.64 ml of 0.01 M EDTA solution for a total endpoint, and 29.32 ml of 0.01 M EDTA solution for a calcium endpoint.
When caffeine is treated with HCl what solvent is the resulting compound more soluble in? Methylene chloride, chloroform, or water When carboxylic acid is treated with a base such as NaOH
Determine the boiling point of a solution of 72.4 g of glycerol dissolved in 122.5 g of water.
For the reaction CO(g) + H2O(g) CO2(g) + H2(g), Kp = 0.64 at 900 K. If the reaction is initiated with just H2(g) and CO2(g), each at a partial pressure of 0.540 atm, what is the partial pressure of CO(g) at equilibrium
