CalcuLate the mass of Naphthalene required to react stoichiometrically with the moles of 2 brom2 methylpropane that were placed in the flask (5 mL of 2 brom2 methylpropane).
Dispense that quantity of Naphthalene into the dish.
Suppose we start with 0.0530 mol of N2O5 in a volume of 5.2 L. How many minutes will it take for the quantity of N2O5 to drop to 0.0253 mol?
Benzene (A) melts at 6 0C and diphenylmethanol (B) melts at 65 0C. The solids are mutually immiscible. There is a eutectic at 1 0C, the eutectic solution being 20 mol % in B, and an unstable compound, AB2,
Celsius is allowed to expand into an evacuated vessel of 2.50 L volume. Does the gas do work? Explain
calculate the initial reaction rate when [O3] & [NO] remain essentially constant at the values [O3]0= 7.48 x 10-6 M & [NO]0= 3.26 x 10-5M, owing to continuous production from separate sources.
Calculating the Equivalent Weight of an Unknown Substance, An unknown organic carboxylic acid, mp = 139-141 degrees Celsius, is burned with a yellow, sooty flame. The sodium fusion test showed that nitrogen was present.
How much faster do ammonia (NH3) molecules effuse than carbon monoxide (CO) molecules? Enter the ratio of the rates of effusion.
Calculate the pH at the 6 points of titration (fraction titrated = 0, 0.25, 0.50, 0.75, 1.0, 1.25). Hint: Since these concentrations are not the same, first calculate the volume of NaOH required to reach the equivalent point.
which is limiting reagent when 42.0g of propane , C3H8, is burned with 115g of oxygen ? how many liters gaseous water are produced at STP
