Explain and calculate the mass of solution in a pipette if the following data has been recorded during a lab experiment:
mass of pipette 0.46g
mass pipette + solution 3.57g
giving that water has a molar enthlphy of vaporization of 40.79 kJ/mol, how many grams of water could be vaporized by 623 J
What is delta S for the conversion of 10 g of supercooled water at -10 degrees Celsius and 1 atm to ice at 10-10 degrees Celsius and 1 atm?
A student assay a solution of H3PO4 by titrating 20.00mL of the solution with .01020M NaOH. An endpoint at ph 5 was observed after 10.11 mL of NaOH had been added.
The decomposition of NO2 (shown below) has a KP = 4.8 × 10-6 at a certain temperature. If 1.36 atm of NO2 is placed in a flask at this temperature
For a formaldehyde and bisulfite reaction, discuss in detail the effect of changing the concentration on reaction rate with respect to each reactant
you have a mixture of oxygen and argon in a 2.50 L container. You know that the oxygen has a mass of 3.44 grams. The total pressure of the gases is 1.86 atm, and their temperature is 22 degrees C.
Molecules are mobile in a gas and some reactions can be run in the gas phase. Give several reasons solutions are preferable for synthetic reactions.
Calculate the equilibrium compostion when 1.00 mol N2 is mixed with 3.00 mol H2 in a 2.00 L vessel.
Calculate the mass of urea that should be dissolved in 201 g of water at 35°C to produce a solution with a vapor pressure of 37.1 mmHg.
If 30.0mL of .150M calcium chloride is added to 15.0 mL of .100 M silver nitrate what will be the final concentration of all ions the remain in the solution?
The age of a rock was was estimated using 238U radiometric dating. The ratio of 238U to 206Pb (238U decays to 206Pb) was approximately equal to 1. If the half-life of 238U is 4.5 billion y, and if it is assumed there was no 206Pb initially, how ol..
Calculate the number of moles of gas in a 3.24 L basketball inflated to a total pressure of 24.3 psi (pounds per square inch) at room temperature (25 degrees Celsius).
