Not your ordinary hard water deposit Have you tried mixing hydrogen peroxide with sulfuric acid in the bowl? Powerful etchant. |

A quick method for separating liquids? @Georg, any chromatography will fail on any pigment? That's incorrect, the classical chromatography experiment is to separate leaf pigments. |

A quick method for separating liquids? Column chromatography, but you will need the appropriate glass tube, powdered silicate and an abundance of the appropriate solvent. This depends highly on what your paints actually are, but this is my "quick" response. |

Energy-efficiency aside, what are the chemical constraints on CO2 capture and methanation? When you first look at the periodic table you can immediately notice the alkali metals on the left and the halogens to the right. Noble gases are normally nonreactive and are being ignored here. Halides as a group tend to be very good at accepting electrons and alkali metals tend to be very good at donating electrons. Reactions such as carbon dioxide reduction require, for a single site, many steps that can be donating or accepting. Transition metals, as a group, tend to have the ability to be very adjustable in their ability to donate or accept e-s and as such are highly useful in catalysis. |

Definitions of autocatalysis The way this question is put is very curious, especially when you say "formal definition." You make it sound like you want something more mathematical. This is too obscure of an interest to have much luck in chemistry, so you'd probably have more luck on math.stackexchange.com |

How to calculate the equilibration time of two connected chambers of salt solution, initially at different concentrations? @picakhu Dispersion in this case is related to diffusion. Any convection in this case is related to diffusion and I don't see why you think this will be dominant. Unless you're stirring there is no bulk convection to consider in the classical treatment. |

How to calculate the equilibration time of two connected chambers of salt solution, initially at different concentrations? @picakhu, I have this book and I opened pg 47 which only speaks about free convection in a vertical tube. These are stirred solutions with a narrow tube connecting them. This is quite different from the situation presented here. Her advisor probably thinks she will be stirring the solution. And I don't think I agree with your definition of dispersion. |
