At 20 degrees C, 0.164 mg of H2 dissolves in 100.0 g of water when the H2 pressure above the water is 1.000 atm. Find the Henry's law constant for H2 is water at 20 degrees C.
what is the structure of an ester of 2-methylpropionic acid that has the molecular formula: C8H13ClO2 and 5 signals in its 1H NMR spectrum?
Draw a structure consistent with the following set of data: a hydrocarbon with a molecular ion at m/z = 68 and an IR absorptions at 3310
The thermal decomposition of phosphate into phosphorous and molecular hydrogen is a first order reaction : 4PH3(g) -----> P(g) + 6H2(g), The half life of the reaction is 35.0 s at 680*c
Change in internal energy E, At 25'C, enthalpy change H for the combustion of liquid octane, C8H8(l), to form CO2(g) and H2O(l) is -5471kJmol-1
A solution that contains 87.2g of an unknown compound in 392.4g of water freezes at -8.00 degrees C. Calculate the molar mass(in units of g/mol) of the solute. Kf of water is 1.86 degrees C/m.
suppose 2.8 moles of methane are allowed to react with 5 moles of oxygen? what is the limiting reagent?How many moles of CO2 can be made from this mixture? How many grams of CO2 would produce?
A sample of 0.0020 mole of HCl is dissolved in water to make a 2000-mL solution. Calculate the molarity of the HCl solution, the [H3O+], and the pH. For a strong acid such as HCI, the [H3O+] is the same as the molarity of the HCl solution.
