How does a nitrogen atom form a bond with 4 hydrogen atoms in amino groups when in water? Why are molecular and ionic formulas important in chemistry? What kind of information do they provide that words don't? How can I differentiate ...
更新2: Please e back.更新3: Please e back michael 更新4: Ca=N-Ca-N=Ca is the molecule of Ca3N2. My question is why Ca2N2 does not exist. But cheungwaito gave an opinion saying that Ca3N2 is not stable? I do not understand.It is impossible to form only one ...
Which of the following does not contribute to the non-covalent interactions that stabilize the helical strands of DNA? a. hydrophobic interactions b. phosphodiester bonds c. hydrogen bonds d. base stacking e. none of the above Could water...
(thus leading to water, or H2O), and nitrogen only three (thus leading to ammonia, or NH3), but carbon can stably hold onto up to four different atoms at once (thus giving us methane, or CH4). Tetravalency is a powerful basis for building molecules that are both strong and ...
Question: Why does atomic radius increase down the group? Periodic Properties: The periodic table categorizes the elements according to their properties and atomic number (number of protons or electrons). Along the period (rows), the atomic number increases. Down the group (columns), chemical pro...
Complete answer: The order from strongest to weakest bonds is: Covalent bond > ionic bond > hydrogen bond >Van der Waals forces. What is the most polar bond in the following list? The answer is b) N - H. The quick answer - right from the get-go, since nitrogen is one of the ...
Which of the following gas has minimum molecular mass? 1) oxygen 2) nitrogen 3) hydrogen 4) methane 1. What is the electron configuration for chlorine? One common ion of chlorine is Cl ^1- . How many valence electrons does...
Still, Martin thinks pursuing green hydrogen is important for all its other uses, like industrial processes and theHaber-Bosch process, which converts hydrogen and nitrogen to ammonia to use in fertilizer. The Haber-Bosch process is credited with massively increasing food production and helping to ...
has more protons and thus the electrons will be closer to the fluorine atom than the carbon atom. This is an unequal sharing of electrons between two bonded atoms and such bonds are known as polar bonds. The bond between the nitrogen and the hydrogen atoms are also similar in case of ammo...
Why do atoms form covalent bonds versus ionic bonds? Which intermolecular forces does a polar molecule have? Which intermolecular forces does a non-polar molecule have? What is the strongest intermolecular force observed for noble gases? Why are covalent bonds between hydrogen and nitrogen or o...
