Calculate the volume of all gases evolved by the complete oxidation of 0.380 of the amino acid alanine if the products are liquid water, nitrogen gas, and carbon dioxide gas; the total pressure is 1.02 ; and = 295.
Compute the equilibrium constant for the reaction between Sn2+ (aq) and Cd(s)
Write balanced net ionic equation for the neutralization of equal molar amounts of KOH and HClO_4
why is it easier to analyze a mixture of atomic species by absorption spectroscopy than it is to analyze a mixture of molecular species?
What weight of malononitrile would be recovered by extraction with (a) three 100-mL portions of ether; (b) one 300-mL portion of ether.
Calculate the work done in Joules (for each case) when one mole of an ideal gas, initially at P = 9atm, T = 298K is expanded isothermally to P=1atm if
What are some reasons why there would be a difference between the expected and actual values for the moles of copper oxide produced from heating copper in the air.
Is the Br2 a gas, and what is the net ionic equation for this reaction?
At high temperatures phosgene (COCl2) decomposes to give carbon monoxide CO and Cl2. In a typical experiment, 0.631 g of COCl2 is injected into a flask of volume 472 cc. When equilibrium is established, it is found that the total pressure is 2.175..
When 3.8 L of propane gas is completely combusted to form water vapor and carbon dioxide at 350°C and 0.936 atm, what mass of water vapor results?
Phosphorous trichloride (PCl3) is produced from the reaction of white phosphorous (P4) and chlorine: P4(s) + 6 Cl2(g) → 4 PCl3(g) . A sample of PCl3 of mass 298 g was collected from the reaction of 75.37 g of P4 with excess chlorine.
Calculate the pH of a solution prepared by dissolving 18.32 grams of benzoic acid and 43.23 grams of sodium benzoate in water sufficient to yield 1.00 L of solution.
How much heat is produced by the complete combustion of 253g of CH4? Ch4(g) +2 O2(g) ----> CO2(g) + 2H2O (g)
