A sample of methane (CH4) has a volume of 25 mL at a pressure of 0.80 atm. What is the volume of the gas at each of the following pressures if there is no change in temperature? a) 0.40 atm; b) 2.00 atm; c) 2500 mmHg; d) 80.0 torr.
How much heat (in J) is evolved or absorbed when a 36.9 g sample of water (specific heat = 4.18 J/(g K)) cools from 87.7oC to 79.2oC
Use the three-step method described in the module to predict the actual precipitates which form (if such is the case) when the following solutions are mixed
Carboxypeptidase A is an exopeptidase, which means that it only cleaves the C-terminal residue from a polypeptide chain. Why is only the C-terminal residue cleaved, and no cleavage in the chain?
Write a detailed sheet/ flow chart for the isolation and purification of 1-bromobutane. Designate how each minor-product is removed form the major product and which layer holds the product in each experimental step performed.
if you burn 10.00g of octane. if the temperature is 500K, and you have an expansion of 1.00 atm, how much work in joule can be done by the system if the octane is completely converted to CO2 and water vapor. what will be the enthalpy change
Draw the Lewis structure of the molecule, assuming that the Cl atoms bond to a single C atom and that there is a C -C bond and two C - O bonds in the compound.
Determine the volume of the sample. (b) Plot the data. Now suppose you add another 5.00 mol of gas molecules into the same volume.
calculate the amount of heat in kJ absorbed if a 200-g sample of water is heated from 22.8 degrees celsius to 41.5 degrees celsius with the specific heat of water being 4.184 J/ g degree celsius
