Sidenote: this reasoning works pretty well for evaporation. There are even quantitative rules that, helped if needed by simple software, predict boiling points to typically 15K accuracy, as well as vapour pressure. But for melting points, which depend completely on packing lots of molecules tightly...
Alright? So you might have heard this in lab before, and all it means is this, this has to do with polarity. Okay? So remember that we learned how to figure out if molecules have a net dipole? That's all there is to it. We're going to figure out, okay, what we're...
In his essay, A Nice Cup of Tea, George Orwell laid out 11 basic principles to make a good cup of tea, from warming the pot beforehand to stirring the leaves before pouring. He insisted that "the water should be actually boiling at the moment of impact, which means that one should ...
Which compound has the lowest boiling point? Using intermolecular forces, predict which compound would have the highest boiling point? Explain when two molecules can interact through a dipole-dipole attraction and when hydrogen bonding may occur. Choose which molecule in each set of pairs h...
In scientific terms, they'rehydrocolloids. When hydrocolloids disperse in a liquid, they bind to the water molecules, which reduces their movement. This reduced movement is apparent to us, as increased viscosity or thickening. The most obvious example of using a stabilizer in cooking is when you...
The sulfur dioxide is used as the beaching agent of food. It is also used as a refrigerant to cool the substances in the refrigerant. The boiling point of sulfur dioxide is {eq}- 10{\rm{^\circ C}} {/eq}. Sulfur dioxide is heavier than air. It is very harmful to the eyes. ...
Also, the cross guard on a European sword can aid point control and manipulation of a blade. Guards can range from a simple crosspiece to a full basket that nearly encloses your hand. Hilt - The handle of the sword, a hilt is usually made from leather, wire or wood. It is fastened...
It's almost impossible to predict when your coffee will be ready. For this reason, percolators are no longer in demand and have been discontinued. Percolators can still be found on Amazon or eBay. They are mainly sold as souvenirs. How to Use a Percolator 1. Weigh your favorite coffee to...
"Covalent bonds are simple molecular substances consisting of molecules that are held together by weak forces, so these substances have a low melting and boiling point." Explain this concept. Also, what makes bonds stable?please answer the question and explain the ...
How does one predict that the chemical bonding between two elements is likely to be ionic? What are ionic bonds and what do they do? Give an example. What are they ways in which atoms bond to one another to form either molecules or ...
