A sample of gas occupies a volume of 364 mL at 1.28 atm and 27 oC. Calculate the volume of the gas if its temperature is changed to 57.0 oC while its pressure is held constant.
solution of the nonvolatile solute ethylene glycol, C2H4(OH)2, in water is prepared. Calculate the vapor pressure of the solution to three significant figures.
If 31.82 g of a metal oxide reacted with excess carbon and 4.08 L of CO2 formed at 100 C and 1.5 atm what is the identity of the metal
Calculate the equilibrium concentrations of NH3 and H2S if a sample of solid NH4HS is placed in a closed vessel and decomposes until equilibrium is reached
What is the boiling point of the solution produced by adding 363 g of ethylene glycol (molar mass = 62.1 g/mol) to 1.5 kg of water? For each mole of nonvolatile solute, the boiling point of 1 kg of water is raised 0.51°C.
A rigid flask is initially filled with 4.00 atm of NO2(g) and no N2O4(g) at 100 C. After equilibrium is achieved, the pressure of NO2 is 1.56 atm.
calculations to determine the amount of ascorbic acid? Does the volume of ascorbic acid solution added before titration influence how much iodine solution will be needed?
A gas originally at 27 degrees celsius and 1.00 atm pressure in a 3.9 L flask is cooled at constant pressure until the temperature is 11 degrees celsius. determine the new volume of the gas and express your answer in Litre.
How many moles of potassium carbonate will be produced if 400.0 g of potassium hydrogen carbonate are heated?
However, if you treat formaldehyde (CH2O) with potassium cyanide in water, you will not produce the cyanohydrin. You may even produce C3H6O3 (i.e., dihydroxyacetone and glyceraldehyde). Explain this either in words or reactions.
What is the silver ion concentration in a solution prepared by mixing 357 mL of 0.392 M silver nitrate with 469 mL of 0.504 M sodium phosphate?
What are bonding theories? Why are they important? What may they be used for. HI has a force contents of 314 Nm^-1 and a bond length of 160.92 pm.
A gaseous compound is 78.14 percent boron and 21 86 percent hydrogen . At 27 degrees celcius, 74.3 ml of gas exerted a pressure of 1.12 atm.
