What is the mole fraction of each component in a mixture of 12.45g of H2, 60.67g of N2 and 2.38g of NH3?already have the answer, I just need to know how to get there. Please explain: NO explanation will get you 1 star, I also can look at the back of a book.
Using the technique of the previous problem ?E was found to be -2,000.00 kJ/mol at 298 K for an unknown liquid hydrocarbon. In another experiment it was determined that for each mole of hydrocarbon
The pressure is steeply increased to 100 bar. The volume of the liquid is decreased by 1 ml at this constant pressure. Find the deltaH and deltaU
Answer the questions below with the data provided: 15 mL of 5% NaOH (w/v) is used to deprotonate the unknown carboxylic acid. The TBME is washed with an additional 10 mL of the NaOH solution and then 20 mL of water which are all combined.
What is the the molar composition of the products when a stream of CH4 is combusted with 5% excess air if you have 1600 moles per hour of methane being fed into the reactor
already have a solution that contains 10 mmol of acetic acid. how many millimoles of acetate will you need to add to this solution? the pKa of acetic acid is 4.74
if the molarity of the HCl solution was actually greater then the lable indicated would it affect the calculated value for the number of moles of HCl that reacted.
A car engine cools efficiently when water is used as a coolant, but the engine does not cool as efficiently with pure ethyl glycol (antifreeze)
A 9.0×10-2 M solution of a monoprotic acid has a percent dissociation of 0.60%. Determine the acid ionization constant Ka for the acid.
The vapor pressure and enthalpy of vaporization of an unknown substance are measured to be 204.2 torr and 28.8 kJ/mol, respectively at room temperature (298.15 K). Estimate the normal boiling point of the substance at an atmospheric pressure of 76..
Blood is essentially an aqueous solution but it must transport a variety of non polar substances hormones for example
when a current of 308 mA is used for 8h, what volume of fluorine gas at 298 K and 1 atm can be produced from a molten mixture of potassium and hydrogen fluoride
Assuming the solution has a heat capacity of 4.18 J/°C·g and assuming no heat loss to the calorimeter, calculate the enthalpy change for the dissolution of NH4NO3 in units of kJ/mol.
