If 1.00 mol of argon is placed in a 0.500-L container at 18.0 C, what is the difference between the ideal pressure (as predicted by the ideal gas law) and the real pressure (as predicted by the van der Waals equation)?For argon, a=1.345(L^2 * atm)/mol^2 and b=0.03219 L/mol.
use the concept mof electron configuration to explain why the number of valence electrons in metals tend to be less the number in most nonmetals.
I dont understand how 'n' in the equation turned into 4.35x10^2...where did that number come from
What is the pH of the final solution when 25 mL of 0.022 M HCl has been added to 35 mL of ) .040 M HCl at 25 deg C
consider the compound alum al2so43 which has a molar mass of 342.14 gmol.a. how many moles of alum are there in 73.6 g
Aquated iron (II) ions undergo a disproportionation reaction to give Fe (s) and aquated iron (III) ions. That is, iron (II) ions are both oxidized and reduced in the same reaction
We do not have a reliable method for determining the number of molar equivalents of bleach being added because commercial preparations vary in concentration and "oxidizing power
I- is oxidized by MnO4- in basic solution to yield I2 and MnO2. The coefficient on H2O in the balanced redox reaction will be
Use the polygon in circle method to construct a pie molecular orbital diagram for the benzene dianion c6h6 -2 and explain why, on this basis, you would or would not expect it to be stable.
Hydrocarbons are often reacted with steam to form H2, as shown for propane: C3H8(g) + 6 H2O(g) 3 CO2(g) + 10 H2(g) Calculate Kp for this reaction at a particular temperature
What is the equation for the net reaction. A+B-->C delta H= -120 C+B-->D delta H=-40
During osmosis A) pure solvent diffuses through a membrane but solutes do not. B) pure solutes diffuse through a membrane but solvent does not. C) pure solvent and a solution both diffuse at the same time through a membrane.
