Why is nh3 A gas and h2o a liquid? given that the nitrogen ATOM has ONLY the one lone pair..the opportunity for intermolecular interaction via hydrogen-bonding isdiminishedwith respect to water. ... i.e. nitrogen IS LESS electronegative than oxygen, and polarity is not pronounced in the am...
Why would a heat treated enzyme behave differently than a non-heated enzyme? Why does diamond have a lower entropy than graphite? Why don't ionic compounds have electrical conductivity as a solid but they do as a liquid? Why is CH_3OH amphoteric?Explore...
Why are water liquid and carbon dioxide gas? Why does the earth's atmosphere contain only small amounts of carbon dioxide? Why doesn't bromocyclopropane react under SN2 conditions? Explain why only one C=C of geraniol is epoxidized with the Sharpless reagent. ...
Efficiency is much more of a product of the cycle type than the fluid. Using H2O, you commit to using a Rankine cycle (because water is liquid at room temperature). An alternative is an all-gas Brayton cycle. There are meaningful differences between these two routes, but what matters even...
You can't see the water vapor, because it's a gas, but it is still there.由于水蒸气是气态的，所以我们看不到它，但它依然真实存在。Water can be either solid as ice, liquid as water, or gas, which is a vapor.水能以固态存在，比如冰；能以液态存在，比如水；或以气态存在，那就是水蒸气...
Why is it necessary to heat the hydrate gently at first and then more strongly only after most of the water has been driven off? Explain why it is important to drink 8 cups of water in a day. What effect does water have on the body? Explain why a liquid should not be di...
aNote in the figure below that the H2O molecules remain H2O regardless of the physical state (solid, liquid, or gas). 不管物理状态固体、液体或者气体,笔记在图在 (那之下H2O分子依然是H2O)。[translate] awho gave me a morning kiss 开始[translate] ...
3. Water as a Universal Solvent: - Water (H2O) is called the universal solvent because it can dissolve more substances than any other liquid. This property is crucial for many biological and chemical processes. 4. Chemical Composition of Water: - Water is made up of two hydrogen atoms and...
Laboratory simulations revealed that adding a splash of H2O makes guaiacol rise to "the air-liquid interface," Bjorn Karlsson and Ran Friedman of Linnaeus University in Kalmar, Sweden reported in the journal Scientific Reports. "Because this drink is consumed at the interface first," they continued...
acomplete combustion produces mainly carbon dioxide (CO2) and water (H2O); however, small quantities of carbon monoxide (CO) and partially reacted flue gas constituents (gases and liquid or solid aerosols) may form. Most conventional fuels also contain small amounts of sulfur, which is oxidized...
