1. Calculate the molar solubility of bbarium sulfate, BaSO4, in 0.010 M Sodium Sulfate, Na2SO4, solution at 25C. Compare this to the solubility of BaSO4 in pure H2O. What is the common ion?
2. We mix 100 mL of 0.010 M Potassium Sulfate, K2SO4, and 100 mL of 0.10 M lead (II) nitrate, Pb(NO3)2, solutions. WIll a precipitate form?
The explosive, TNT, is composed of 37.0% carbon, 2.2% hydrogen, 18.5% nitrogen and the rest oxygen. if the molar mass of TNT is 227 g/mol, what is the empirical and molecular formula for TNT?
One cup is equivalent to 237. mL. If 1 cup of oil has a mass of 210. g, what is the density of the oil (in grams per cubic centimeter)?
Choose an acid below and determine how much of the acid in mL that you need to add to 0.800 g of the sodium salt of its conjugate base to prepare a buffer with a pH of 3.8. 3.0 M formic acid
we are doing an analysis of cola lab in my chem I lab. We have to do pre-lab questions and one of them is- how will you use compounds of different colors to determine the relationship between percet transmittance and wavelength? or between absorba..
a mixture of 2- percent ammonia 55 percent hydrogen and 25 percent nitrogen by a volume 9.8 newton per square meter. what is partial pressure of ammonia?
While shutdown, the core accidentally went critical and the reactor pressure vessel rose in temperature and was hot for two hours, but all instrumentation has failed and no one is sure what the temperature was.
Calculate the average molecular weight of a gaseous mixture with the following composition on a mole % basis: CH4= 30%, H2= 10% and N2= 60%.
The solubility of oxygen in lakes high in the Rocky Mountains is affected by the altitude. If the solubility of O2 from the air is 2.67 × 10-4 M at sea level and 25°C.
A 4.000-g sample of the metal nitrate M(NO3)2 was dissolved in water and treated with excess aqueous sodium sulfate. The sulfate salt that formed weighed 3.318 g. Determine the identity of the metal.
Calculate the number of molesof each reactant. Determine the limiting reactant in each of the following three reactions. The limiting reactant that you determine here will be used directly in this experiment.
