A sample of 4.60 g of methane occupies 11.0 dm3 at 310K. Calculate (a) the work done when the gas expands isothermally against a constant external pressure of 200 Torr until its volume has increased by 3.6 dm3, and (b) the work that would be done if the same expansion had occurred reversibly.
Another solution of the same chemical is measured under the same conditions and has an absorbance of 0.81. What is its concentration?
Why is gravity filtration and not suction filtration used to remove suspended impurities
a) If the initial sample is 8.50 g, what mass of the original iridium-192 remains after 130 days? b) Estimate the half-life of the radioisotope. c) How many days would it take for one-fourth of the sample to decay?
What you need to know about Problems, The Ksp of La(IO3)3 is 1.0×10-11. Using activities, what is the molar solubility of La(IO3)3 in a 0.050 M solution of NaNO3?
A solution of 62.4 g of insulin in enough water to make 1.000 L of solution has an osmotic pressure of 0.305 atm at 25°C. Based on these data, what is the molar mass of insulin?
Calculate the molarity of a solution of 25.2mL of methanol combined with enough water to make 622mL of solution (density of methanol is 0.79180g/mL).
A total of 0.155 of this subunit was dissolved in enough water to produce 2.00 of solution. At 28 the osmotic pressure produced by the solution was 0.138 . What is the molar mass of the protein?
Assuming that the water is contaminated, devise a method for disposing of the contaminated water without contaminating the environment, but allowing the recycling plant to resume operations as soon as possible.
determine if a redox reaction would occur if you were to mix them in a single solution. For those pairs of substances that would not react, calculate the EOCELL of the unfavored reaction between the two substances.
When 1 of a fuel is burned at constant pressure, it produces 3452 of heat and does 13 of work. What is the value of delta H for the combustion of the fuel?
Write equations for the reaction of each of the following with (1) Mg in ether followed by (2) additione of D2O to the resulting solution:
Compounds with nearly identical molar masses often have very different physcial properties. Choose the compound with the lower value. Solubility in water: di-ethylether or 1-butanol. Why is it lower?
