A homogeneous solution of hydrated ions is initially observed, when a further 1 g of KCI is added, this additional KCI is also observed to dissolve. O d. A homogeneous solution of hydrated ions is observed before spontaneous crystallisation of KCI occurs when the solution is poured onto a crystal of KCI.

Nitrogen dioxide is one of the many oxides of nitrogen (often collectively called "NOx") that are of interest to atmospheric chemistry. It can react with itself to form another form of NOx, dinitrogen tetroxide. A chemical engineer studying this reaction fills a 50 L tank with 22. mol of nitrogen dioxide gas. When the mixture has come to equilibrium she determines that it contains 6.0 mol of nitrogen dioxide gas. The engineer then adds another 5.5 mol of nitrogen dioxide, and allows the mixture to come to equilibrium again. Calculate the moles of dinitrogen tetroxide after equilibrium is reached the second time. Round your answer to 2 significant digits. mol D X S
