Exactly 100 pounds of cane sugar (dextrose), C12H22O11, were accidentally discharged into a small stream saturated with oxygen from the air at 25 celcius. How many liters of this water could be contaminated to the extent of removing all the dissolved oxygen by biodegradation?
Compute the density of dry air and molar mass at zero degree Celsius temperature and 1.0 atm of pressure.
The coinage metals-copper, silver, and gold-crystallize in a cubic closest packed structure. Use the density of copper (8.95g/cm3) and its molar mass
Include all constitutional isomers(except those with carbon-carbon double bond or triple bonds). For each constitutional isomer, identify the functional group and indicate whether there are stereoisomers other than conformers.
How many liters of CO2 will be produced with the complete combustion of of methane (CH4) with 4.3L of oxygen?
Using the Nersnst Eqaution [E=E^0 + (RT/nF)In(a1/a2) ] in terms of teh partial pressures of the components (specify assumptions). Also, calculate the Gibbs Free energy of the complete rxn.
Osmium has a density of 22.6 g/cm3. What volume would be occupied by a 21.8 g sample of osmium?
The reference electrode is attached to the positive terminal of the potentiometer, and the silver electrode is attached to the negative terminal. The solubility constant of TlBr is Ksp = 3.6 × 10-6 and the solubility constant of AgBr is Ksp = 5.0 ..
What kinetic energy must the electrons have in order to resolve a protein molecule that is 5.10 nm in diameter? Take the mass of an electron to be 9.11× 10-31 kg.
If 60.0 g of H3PO4 is dissolved in enough water to form 175 mL of solution, what is the molarity (M) of the solution?
Calculate the Z for the fourth ionization of Ti when it requires 425.6 kJ of energy to ionize 0.185 moles of Ti^3+ to Ti^4+ ( The electron being removed is in the outermost valence orbital of Ti^3+ ground state, therefore n = 3)
What is the mass of a piece of concrete that starts at 90.0 C, us immersed in a calorimeter with 350.0 g of water at 26.0 C
A piece of metal ore weighs 8.25 g. When a student places it into a container of water, the liquid level rises from 21.25 mL to 26.47 mL. What is the density of the ore?
