Consider the titration of 100.0 mL of 0.100 M NaOH with 1.00 M HBr. Find the pH at the following volumes of acid added and make a graph of pH versus Va: Va = 0, 1,5,9, 9.9, 10. 10.1. and 12 mL.
a compoud is known to contain only carbon, hydrogen and oxygen. If the complete combustion of a .150 g sample of this compoud produces
SO3 can be produced in the following two-step process: FeS2 + O2 ---> Fe2O3 + SO2 , SO2 + O2 ----> SO3 Assuming that all the FeS2 reacts, how many grams of SO3 are produced when 20.0 g of the FeS2 reacts with 16.0 g of O2?
calculate the approximate concentration of the solution in mol/kg and determine the volume change of the ballon when it ascends from 1 atm pressure to 240 torr pressure ?
Calculate the molar solubility and the solubility of iron (II) hydroxide in pure water then in 0.125M NaOH(aq).
Why would be difficult to isolate neutral p-aminobenzoic acid. What effect will pH have on the structure of your product
N2O2 draw valence bond drawings for the resonance forms-clearly labeling the sigma and pi bonds and hybrid orbitals.
The reaction vessel is charged initially with SO3(g) and NO(g), each at a partial pressure of 0.500 atm. In the space below, enter the equilibrium the partial pressure of SO2(g) in units of atm
a) what is the total pressure in the reaction vessel b) what is the partial pressure of N2 c) If the volume of the reaction vessel is decreased to 5.0 L, would you expect the pressure of the gases to increase or decrease
What is the molecular formula of a gas that has a density of 1.88 g/L at STP? this is not the actual numbers but it would be nice to know how to do this.
Draw both conformers and suggest which of them is stable. Suggest a reason why the unstable conformer is unstable.
What is the pH of the solution created by combining 8.00 mL of the 0.10 M base with 8.00 mL of the 0.10 M acid?
What is the net ionic equation for the following redox reation in basic solution? CrO4{2-} oxidizesHSnO3{-} and reduces to CRO2{-}
