find 10 moles in KCl

Suppose we have 8 distinguishable particles that have a total energy equal to 6 units. The distribution for this system are labelled (no, n1, n2 , n3 ). Calculate the number of microstates (W) for each of the following distributions; (a) ( 6, 0, 0, 2), (b) ( 5, 1, 1, 1), (c) (4, 2, 2, 0), (d) (2, 6, 0, 0)

What will be the number of microstates (W) when 10 molecules are equally distributed among five energy levels.What is the value of W if one molecule is removed from one state and added to another?

In the Tools menu, check Width to enable a ruler below the box. Drag the handle on the left and adjust the length of the box to 5 nm. (Because no other dimensions of the box change, its length can be used as a substitute for volume.) Pump the pump handle once fully. This should add 40 to 50 gas molecules to the container. The pressure gauge will fluctuate a little bit, so watch it for a minute to estimate an average value. Record the pressure in the table.

In the Constant Parameter menu, select Temperature. Then drag the handle of the box to change its length to each of the other values in the data table. Record the pressure for each length.

N₂+ 3H₂ → 2NH₃ If 14.00 g of N₂ reacts with the correct amount of H₂ and produces 17.03 g of NH₃ then what mass of H₂ is required for a complete reaction, with no waste reactant?
