Answer to: (a) If a substance has a high melting point, is it more likely to have an ionic or covalent bond? (b) Why? By signing up, you'll get...
Which substance has the highest melting point? a. silicon carbide, SiC b. phosphorus pentachloride, PCl5 c. sulfur, S8 d. phosgene, COCl2 Rank the following in order of increasing melting point: *NF3 *NCl3 *PCl3 *KCl *CO2 *H2O *H2 Why do the boiling...
OK. We’ll find out the later if you were right. Now, whether it’s TV shows like ‘The Apprentice’ or the big success of companies in California’s Silicon Valley, the last decade saw a huge growth in 20 and 30-year-olds starting...
Graphene has a very high melting point and isvery strong because of its large regular arrangement of carbon atoms joined by covalent bonds. Like graphite, graphene conducts electricity well because it has delocalised electrons that are free to move through its structure. Why is graphene the stronge...
and spintronic devices11,12. Growth of ZnO on Si is vital for integrating this material into the present microelectronic technology. One peculiar observation that has become more easily apparent with the growth of ZnO nanowires is that on substrates such as glass and silicon, that do not provide...

Glass, usually made of silicon dioxide,doesn't change its shape over the short timescales relevant to humans, says chemist Paddy Royall of the University of Bristol, England. (If it does change shape, that process takes billions of years.) ...
Sorry if I'm dumb, but Apple silicon is ,according to rumors, supposed to be more power efficient generate less heat but also more powerful (a14x better than core i9?) and also be cheaper. Then why has x86 ever become popular/the standard if Apple silicon/Arm is, I guess, better...
Discovered by Johannes Diederik van der Waals, these forces are known to have lower melting points and high dependence to distance between molecules. Answer and Explanation: In the periodic table, Fluorine is located on top of Chl...
(1) completely. From the horse's mouth - er, fingers - "However . . . several web sites talk about PTFE having very weak van der Waals forces.That has got to be completely untrue.If it had very weak van der Waals forces, it would be a gas - not a fairly high melting point ...
