Why is water less dense as a solid? What makes water such an attractive recrystallizing solvent, especially when done on a large industrial scale? Why do non-polar substances not dissolve in water? Why is pure water neutral? Why should the recrystallization solvent have a fairly low boiling ...
Waste can bring a lot of problems. Although China has rich resources(资源), we are short of something, such as fresh water. It is reported that we will have no coal or oil in 100 years. So if we go on wasting resources, we will use nothing in the future. We should say no to th...
Cyclohexanone does not form hydrogen bonding with the water molecules because cyclohexanone is a non-polar molecule. Also, water has an asymmetrical... Learn more about this topic: Compound Solubility in Water | Overview & Examples from Chapter 6/ Lesson 5 ...
A molecule is considered polar if it has an overall dipole moment. The dipole moment of the compound depends if the compound has polar bonds and if the geometry of the compound will permit a net dipole moment. Bond dipole moments occur due to differences in electronegativity....
The researchers discovered a set of genes 7 ( regulate ) by the chemical compound superoxide, which 8 ( associate ) with metabolic activity. And they found by stopping the production of superoxide, they also stopped the effect of sugar 9 these circadian clock genes in the evening, 10 ( reve...
This makes waterpolar, meaning it has negative and positive poles (similar to how a magnet has north and south poles). The polarity of water means it is attracted to other polar molecules, as well as to charged particles like ions. Consequently, water is good at dissolving awhole lotof ot...
what water is. Water is a two-hydrogens-one-oxygen molecule, in which the atoms are kept together by a polar bond. On top of that, one could also picture hydrogen and oxygen as small balls with peculiar appendages, which would allow them to fit together, and water could be imagined to...
