You measure 2.34 g of K2Cr2O7 into a volumetric flask. You dilute the K2Cr2O7 with water to a volume of 250 mL. It takes 35.7 mL of this solution to titrate 17.8 mL of a solution of Na2C2O4 in the presence of excess acid. What was the concentration of the original Na2C2O4 solution?
why is it important to have gas laws relating to this hypothetical situation?
mgnh4po4.6h2o loses h2o stepwise as it is heated. between 40c and 60 the monohydrate is formed and above 100 celcius
Calculate the pH at the equivalence point for the titration of 0.20 M HCl with 0.20 M NH3 (Kb = 1.8x10-5)
How many grams of aluminum hydroxide are obtained from 18.2g of aluminum sulfide?
If the density of mercury is 13.6 g/mL. What is the mass in grams of 15.6 L of mercury?
A 30.5 g sample of an alloy at 91.8°C is placed into 50.5 g water at 22.1°C in an insulated coffee cup. The heat capacity of the coffee cup (without the water) is 9.2 J/K.
It takes 208.4 kJ of energy to remove 1 mole of electrons from 1 mole of atoms on the surface of rubidium metal. How much energy does it take to remove a single electron from an atom on the surface of solid rubidium
If it takes 526 J of energy to warm 7.40 g of water by 17 °C, how much energy would be needed to warm 7.40 g of water by 55 °C?
A 354 gram sample of C6H12O6 has a pressure of 648 torr at 31°C. What is the volume (L) of the container?
Calculate E°cell and indicate whether the overall reaction shown is spontaneous or nonspontaneous. O2(g) + 4H+(aq) + 4e- Picture 2H2O(l); E° = 1.229 V Al3+(aq) + 3e- Picture Al(s); E° = -1.662 V Overall reaction: 4Al(s) + 3O2(g) + 12H+(aq) ? 4Al3+..
write the chem equation for the reaction which occurs when solutions of potassium sulfide and iron (II) chloride are mixed.
The temoerature rose by 3.65C. Next, a small piece of calcium carbonate was placed in the same calorimeter and .100L of dilute HCl was poured over it.
