Acid rain is caused in part by burning coal that contains sulfur impurities. The sulfur is converted first to SO2, which reacts with oxygen and atmospheric moisture to produce sulfuric acid, H2SO4. If a particular coal contains 1.45% sulfur (by mass), calculate the mass of sulfuric acid produced by burning a metric ton (1000 kg) of the coal.
The methyl benzoate and acetanilide react with HNO3, H2SO4, and glacial acetic acid. Need to know the possible products and then the one that actually forms.
Calculate the mass of aluminum deposited on the purified aluminum metal by the application of a current of 1.225 kiloamperes for 30 minutes from a very large quantity of a solution containing Al3+ ion in the Al2O3/Na3AlF6 molten state.
Identify the substance produced in the liver that helps catalyze this reaction.
an aqueous solution of an unknown solute is tested with litmus paper and found to be acidic. the solution is weakly
a 60 liter tank containing an ideal gas at a pressure of 40 atmospheres is connected by a valve to a 30 liter tank of
How come when you add an electron to an anion, the ionic radius increases, but as you go right across a periodic table, atomic radius decreases
Calculate the percent dissociation of the acid to 3 significant figures. % ============= 2. The pH of a 4.28×10-3 M solution of a weak base that will accept only one proton is 7.17. Calculate the percent dissociation of the base to 3 significant f..
The binding energy of electrons to copper metal is 389.3 kJ/mol. What is the longest wavelength of light that will eject electrons from copper metal? Enter units.
What is the volume occupied by 25.6 g of argon gas at a pressure of 1.41 atm and a temperature of 411 K?
If Ka is 1.85 x 10-5 for acetic acid, what is the pH of the solution at the equivalence point during a titration of 50.0 mL of 0.100 M acetic acid with 0.100 M NaOH
Explain why a solution of one mole of potassiium carbonate in one litter of water has higher boiling point than a solution of one mole of sodium bicarbonate
Consider the air pollutants NO and NO2, contributors to photochemical smog. Both can be formed by the reation between atmospheric nitrogen and oxygen. At 25 C
