Carbon Monoxide at a pressure of 720 mmhg reacts completely with O2 at a pressure of 360 mmhg in a sealed vessel to produce CO2. what is the final pressure of the flask?
Calculate the number of molecules in 37.0 mL of ethanol, CH3CH2OH. The density of ethanol is 0.789 g/mL.
A gas mixture with a total pressure of 750mmHg contains each of the following gases at the indicated partial pressures:CO2 , 133mmHg ; Ar,215mmHg and O2,177mmHg
Calculate the percent yield for the reaction. A scientist performs this reaction in the lab by starting with 30.02 g of Mg and 0.992 moles of Cl2 gas
What is the freezing point of a solution of aluminum chloride that contains 42.0 g AlCl3 dissolved in 530. g of water?
An unknown compound contains only carbon, hydrogen, and oxygen. Combustion of 4.00 g of this compound produced 5.87 g of carbon dioxide and 2.40 g of water.
Assuming the solution has a heat capacity of 4.18 J/°C·g and assuming no heat loss to the calorimeter, calculate the enthalpy change for the dissolution of NH4NO3 in units of kJ/mol.
Compute the equilibrium constant, Keq, for the reaction of equimolar amounts of acetophenone, C6H5COCH3, and hydroxide ion to generate the enolate ion.
if 6.73 g of NaCo3 is dissolved in enough water to make 250. mL of solution what is the molarity of the sodium carbonate ?
Calculate the maximum number of moles and grams of H2S that can form when 152 g aluminum sulfide reacts with 147 g water.
25 g of a certain metal is heated in boiling water and then poured into 90 mL of water initially at 22.0oC. After the water has resumed a constant temperature.
assuming that the gas behaes ideally. Then repeat the calculation by using the van der Waals equation
A muon is an elementary particle with a negative charge equal to the charge of an electron and a mass approximately 200 times that of the mass of an electron.
