Calculating equilibrium constants from equilibrium concentrations …

And since there's an implied one in front of N2O4, this is the concentration of N2O4 raised to the first power. Next, we plug in our equilibrium concentrations. So the equilibrium concentration of NO2 is 0.0172. So let's plug that in. So this is equal to 0.0172 squared divided by the equilibrium concentration of N2O4, which was 0.00140.

Calculating equilibrium concentrations from initial concentrations …

The concentrations in an equilibrium constant expression are equilibrium concentrations, therefore we can plug in the equilibrium concentrations from our ICE table. So the equilibrium concentration for BrCl was two x, the equilibrium concentration for Br2 was 0.60 minus x, and the same for chlorine, so we can plug that in as well.

Using an ICE Table | ChemTalk

Le Chatelier's principle is especially relevant to ICE tables because the change in the ICE table represents the shift in the position of equilibrium: that means that if the change shows an increase in concentration of reactants, then there will be a subsequent decrease in the concentration of products. Vice versa as well: if the change shows ...

Auschwitz | Holocaust Encyclopedia

Like some concentration camps, Auschwitz I had a gas chamber and crematorium. Initially, SS engineers constructed an improvised gas chamber in the basement of the prison block, Block 11. Later a larger, permanent gas chamber was constructed as part of the original crematorium in a separate building outside the prisoner compound.

Percent Concentration. One way to describe the concentration of a solution is by the percent of the solution that is composed of the solute. This percentage can be determined in one of three ways: (1) the mass of the solute divided by the mass of solution, (2) the volume of the solute divided by the volume of the solution, or (3) the mass of the solute divided …
