Part a background information; solution already calculate the change in enthalpy (δh) for 1.0 mol of carbon dioxide (co2) initially at a volume of 5.00 l and a temperature of 298 k to a final volume of 10.00 l and a temperature of 373 k. explicitly state all assumptions along with a justification for any and all assumptions made. express your answer in units of kilojoules per mole (kj/mol)

the part i need with;

part b: the enthalpy is a common form of energy used in biochemical thermodynamics and is a state function, meaning the change in enthalpy (δh) for the process above should be independent of the path. explicitly illustrate this point by calculating the change in enthalpy for the expansion process above along a different path than you did in part (a) of this problem

not sure how to calculate along a different path. show work.

Since the gas in your graduated cylinder is a mixture of butane and water vapor, you must determine the partial pressure of the butane, pbutane, alone. to do this, consult a reference and record the partial pressure of the water vapor, pwater, at the temperature you recorded. use the following formula to compute the partial pressure of the butane. pbutane = atmosphere - pwater use the following combined gas law formula and compute the volume that the butane sample will occupy at stp. (hint: convert both temperatures to kelvin.) pbutane x voriginal = pstandard x vfinal troom tstandard use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. grams of butane you used “x” grams of butane ml of butane corrected to stp = 22,400 ml compute the theoretical molar mass of butane based on its formula and the atomic masses on the periodic table. compare your experimental results from #3 to the theoretical value of #4, computing a percent error of your findings using this formula: % error = measured value - accepted value x 100 accepted value use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. need asap

Select all of the statements which are true. electrons are located in shells or orbits around the atom. electrons orbit slowly around the atom. electrons travel in one flat path around the nucleus of an atom. the valence of an atom is determined by the number of electrons in the atom's outermost shell.

How are evaporation and sublimation similar? a both involve the formation of a gas. b both release energy to the surroundings. c both take place throughout a solid. d both take place at the surface of a liquid.
