Why are active on-duty firefighters likely to experience the adverse health effects from inhaling 300 ppm of carbon monoxide faster than nonactive off-duty firefighters who inhale the same concentration of the same substance?
A solution is prepared by mixing 500. mL of 0.10 M NaOCl and 500. mL of 0.20 M HOCl. What is the pH of this solution? [Ka(HOCl) = 3.2x10-8]
A reaction vessel contains these compounds at equilibrium. What will happen if the volume of the container is reduced by 50% at constant temperature?
Using the van der Waals equation, calculate the pressure exerted by 15.0 mol of carbon dioxide confined to a 3.00-L vessel at 56.0 oC. Note: Values for a and b in the van der Waals equation: a = 3.59 L2.atm/mol2, and b = 0.0427 L/mol.
In an acid-base titration experiment, 50.00 mL of a 0.0500 M solution of acetic acid (ka=1.75 x 10^-5) was titrated with a 0.0500 M solution of NaOH at 25 degree C
3.64 g of calcium hydroxide react with excess sodium sulfate in aqueous solution to produce solid sulfate and aqueous sodium hydroxide. How many moles of calcium atoms are reacting ?
A laboratory method of preparing oxygen gas involves decomposition of solid potassium chlorate. The products of the reaction are solid potassium chloride and oxygen gas.
The original conditions on a container filled with gas at a constant temperature are 180 cc and 300 mm Hg. The desired new volume is 90 cc.
A tank contains helium gas at 490. mmHg, nitrogen gas at 0.750 atm, and neon at 520. torr. What is the total pressure in atm?
how many kilojoules and kilocalories of heat are required to raise 40.0 g of water from -12 degrees Celsius to 130 degrees Celsius?
The value of Kf for cyclohexane is 20.0°C/m, and its normal freezing point is 6.6°C. A mass of 1.604 g of a waxy solid dissolved in 10.000 g of cyclohexane results in a freezing point of 4.4°C. Calculate the molar mass of the solid.
if the half life of a certain radioactive element is 1,250 years what is the percent of atoms remaining after 7,500 years is ?
A powder contains FeSO4·7H2O (molar mass = 278.01 g/mol) among other components. A 3.585-g sample of the powder was dissolved in HNO3 and heated to convert all iron to Fe3
