why is vapor unlikly to behave as an ideal gas near the temperature at which the vapor would liquefy
To this was added 20.0 ml of DI water making to the total volume 30.0 ml. The concetration of the unknown acid was 0.868 M. What was the concentration of the original acid?
The ethylenediaminetetraacetate ion, H2Y 2-, forms a strong complex with the calcium ion. How does the addition of the H2Y 2- affect the molar solubility of Ca(OH)2? Explain.
a battery has a volume of 1.78l and contains 3.28x10^3 grams of sulfuric acid, what is the density of sulfuric acid in g/ml?
A strip of aluminium of mass 42.7g is dropped into a beaker of dilute hydrochloric acid. Calculate the work done (in J) on the surrounding atmosphere (1atm pressure, 24oC ) by the evolution of hydrogen in the subsequent reaction
At what Kelvin temperature will the reaction proceed 4.50 times faster than it did at 309 K?
explain why granulated activated charcoal is considered to be the best available treatment technology for dioxins in water.
At what wavenumber would you expect to see an absorbance in the IR if your sample contained water as an impurity?
Each 1.000 g of 238U that decays eventually produces 0.866 g of 206Pb. If the half-life of 238U is 4.468 x 10^9 years, what is the age of a mineral that has a 238U/206Pb mass ratio of 2.00?
If 37.4 grams of water decomposes at 297 Kelvin and 1.30 atmospheres, how many liters of oxygen gas can be produced? 2 H2O (l) yields 2 H2 (g) + O2 (g)
Sulfuric acid (H2SO4) is a very strong diprotic acid. If 0.025 moles of sulfuric acid is mixed with water to make 115 mililiter of solution, what is the molarity of H+?
The pH of a sample of rain is found to be 4.0. Calculate the percentage of HSO4- that is ionized in this sample, given that the acid dissociation constant for the second stage of ionization of H2SO4 is 1.2E-2.
