A 25.0 mL sample of river water was titrated with 0.0010 M Na2Cr2O7 and required 8.3 mL to reach the end-point. What is the chemical oxygen demand, in milligrams of O2 per liter, of the sample?
If a solution is made by adding 83 grams of sodium hyroxide to 750 ml of water what is the percent by mass of sodium hydroxide in this solutions ?
Climbers sometimes develop Acute Mountain Sickness (AMS) when ascending too rapidly without allowing their bodies time to acclimate to the lower oxygen concentrations in air at high elevations.
The reaction SiH4 --> Si + 2H2 has a k= 0.048M/min at 500 degrees Celsius and k= 49.0M/sec at 700 degrees celsius.
At 1000K , the value of Kc for the reaction C+H20 CO+ H2 is 3.0*10^-2. Calculate the equilibrium concentrations of H20, CO2, and H2, in a reaction mixture obtained by heating 5.70 mol of steam and an excess of solid carbon in a 5.50 L container.
At a certain temperature the vapor pressure of pure benzene and pure toluene are 380 torr and 130 torr, respectively.
The enthalpy change for melting ice at 0°C and constant atmospheric pressure is 6.01 kJ/mol. Calculate the quantity of energy required to melt a moderately large iceberg with a mass of 1.39 million metric tons. (A metric ton is 1000 kg.)
A compound contains only carbon, hydrogen, and oxygen. Combustion of 10.68 mg of the compound yields 16.01 mg CO2 and 4.37 mg H20.
