One mole of an ideal gas at 400 K is reversibly and isothermally compressed from a volume of 25.0L to a volume of 10.0L. Because it is very large, the temperature of the surrounding remains essentially constant during the process. Calculate deltaSsystem, deltaSsurroundings and deltaStotal.
The chemical nature of an element is independent of A. its atomic number. B. the number of protons or electrons present in it. C. the number of neutrons present in it. D. none of these.
A temperature increase of 67.4 K was recorded after 1.500 g of metallic magnesium (24.305 amu) reacted completely with 100.0 mL of 1.00 M aqueous HCl in a non-ideal coffee cup calorimeter with a heat capacity of 16.0 J/K.
Solutions of sodium carbonate and silver nitrate react to form solid silver carbonate and a solution of sodium nitrate. A solution containing 3.60g of sodium carbonate is mixed with one containing 5.14 of silver nitrate.
An experiment requires 45.8 g of ethylene glycol, a liquid whose density is 1.114 g/mL. Rather than weigh the sample on a balance, a chemist chooses to dispense the liquid using a graduated cylinder.
Describe the intermolecular force that must be overcome in converting each of the following from a liquid to a gas
What will be the molarity of a compound (1 litre) with a molecular weight of 169 and purity as 41%.
How many moles of Allyl Sulfide (C3H5)2S in 23.2g? How many H atoms are in 0.85 mole of allyl sulfide?How many atoms of Carbon are in 4.20 X 10^23 molecules of allyl sulfide.
Iranian President Mahmoud Ahmadinejad has a mass of 130 lbs. If Iran abandoned it's nuclear energy program and instead converted its President entirely to energy
If toluene(density 0.87) were used to extract ethylene bromohydrin (density 2.41) from an aqueous solution.
Seperate this redox reaction into its component half reactions( use the symbol e- for an electron)
If solubility of a gas is 7.5 g/L at 404 kPa pressure, what is the solubility of the gas when the pressure is 2021 kPa?
The pH of the resulting solution is 2.65. Calculate the Ka for the acid.
