At high pressures, real gases do not behave ideally. Use the van der waals equation and data in the text to calculate the pressure exerted by 18 gram of H2 at 20C in a 1.00L container. Repeat the calculation assuming that the gas behaves like an ideal gas.
Which has the larger hydration energy, AL+3 or Li+ (Both ions are about the same size)
What is the ionization state of aniline (protonated, deprotonated, or a mix) at pH 1, 4.6, and 14?
Nitric acid is gernerated by the action of sulfuric acid on sodium nitrate. Nitrous acid is prepared by the action of hydrochloric acid on sodium nitrite. Why is nitrous acid prepared in situ rather than obtained from the reagent self.
When 1717 J of heat energy is added to 40.0 g of ethanol, C2H6O, the temperature increases by 17.5 °C. Calculate the molar heat capacity of C2H6O.
we had used a red dye, what changes would you make in your experimental procedure to determine the rate law for the oxidation of the red dye by sodium hypo-chloride?
Calculate the dye concentration. (3) 5.00 mL of 0.00500 M ferric nitrate is added to 5.00 mL of nitric acid and 10.0 mL of 0.00250 M thiocyanate solution. Calculate the initial Fe3+ concentration before reaction.
The two phases are allowed to come to equilibrium with their product ammonia in a vessel of fixed volume and at a temperature
Describe how this observation is consistent with the law of conservation of charge.
What type of error is this associated with the concentration of Cu2+ and why is it so? what is the concentration (in mole/L or M) of Cu2+ and NO3- in the final solution
If a few drops of water on the outside of the hot water syringe used to dispense the 5.00 mL sample into the calorimeter well for the Kcal determination fell into the well
100 mL of a 0.125 M solution of HBr was titrated with a 0.100 M solution of KOH at 25 C. The equivalence point will be reached after addition of what volume of the titrant?
what is the number of valence electrons for nh4+ and what is the lewis structure for that molecule. and how many remaining electrons are there and how do you find the formal charge.
