‘It doesn’t mean that every time we’re bloated, we have a GI problem and need to be concerned.’ What is concerning is if any of the problems above are chronic, meaning they come and go for an extended period of time. ‘There are many definitions of a chronic condition, but in...
For example, could I use HCl to separate Bi3+ and Ag+ from Ni2+? Why does sugar dissolve but not dissociate in water even though it is a polar molecule? How do I tell if something can dissolve into another? For example, how would I tell if a solvent will dissolve in salt, NaCl?
All-over color is a great option if you want to cover gray hair, want to complement a new, edgier hairstyle or want something completely different than your natural color. Heres why you might want to choose highlights: You're looking or a subtle change. Highlights are more about accenting...

The best way to tell if something will dissolve is to look at the polarities of the solvent and the solute. If the polarities of the solvent and solute match (both are polar or both are nonpolar), then the solute will probably dissolve. If the polarities of the solvent and solute are...
For mortar and plaster, the best compatible materials are inorganic, and set through a reaction forming insoluble products. The distribution of the consolidant should match the degraded substrate and produce a homogeneously distributed porosity (ideally similar to that of the original system). ...
2) Muller and glass slab – A muller is a special tool used to grind pigments into a carrier such as linseed oil. Glass is used most often because it’s not porous and easy to clean. If you don’t have a muller, improvise! I’ve had luck using the flat side of a piece of glas...

Like detergents, soaps work by surrounding particles of grease or dirt with their molecules, thereby allowing them to be carried away. Unlike detergents, soap reacts with the minerals common in most water, forming an insoluble film that remains on fabrics. For this reason soap is not as ...
