Kwayoyin nauyi: jigon da sinadaran nuna alama, hanyoyin tabbatar da dalilin

A kwayoyin nauyi ne nauyi dukkan kwayoyin halitta na dauke a cikin Game da kwayoyin. Wannan nuna alama da aka bayyana a cikin amu (Atomic taro raka'a).

A sunadarai wani lokacin darajar lasafta a kilo. Don wannan karshen, shi ne ta tara da 1.66057 * 10 ^-27. Wannan lambar ita ce 1 amu taro yayi dace da 1/12 da kuma nauyin daya zarra nuclide ¹² C. A mafi yawan lokuta, yin amfani da dangi kwayoyin nauyi, wanda shine kwayoyin nauyi rabo daga cikin nauyi na daya atomic naúrar.

Shi ne ya kamata a lura da cewa wannan adadi zai taimaka wa faye hali da taro na wani kwayoyin da duk isotopes cewa, samar da m sinadaran fili.

A macroscopic naúrar adadin abu, da ake kira "mol" shi ne wani m yawan barbashi - kwayoyin halitta ko kwayoyin, wani electron ko ion nau'i-nau'i. Wannan adadin shi ne 6.022 * 10 ²³ (ake kira Avogadro m). Don samun zumunta kwayoyin nauyi, kwayoyin nauyi dole su yawaita a da lambar kuma raba shi da samfurin na Avogadro m da taro na daya atomic naúrar.

Kamar yadda ƙaddara da kwayoyin nauyi na abu?

A mafi sauki hanya domin sanin wannan siga ne in yi amfani da musamman dabara, bisa ga abin a fili dole nauyi raba da ta lambar.

Idan muka sani da sinadaran dabara na wani fili wanda kwayoyin nauyi ne sauƙi m via lokaci-lokaci tebur, saboda shi, wannan darajar da aka nuna ga kowane abu da kuma ta m ordinal lambar. Ya isa a samu Naira Miliyan Xari da kwayoyin kaya masu nauyi daga abin da aka gyara na connection.

A cewar Avogadro ta Shari'a, a cikin wannan adadin gas dauke da wannan adadin kwayoyin barbashi. A ra'ayi na wannan alamu Mendeleev-Clapeyron lissafi aka samu. Kwayoyin taro na gas za a iya ƙaddara ta amfani da dabara. Ga lissafin kana bukatar ka sani da yawa Manuniya - nauyin da abu, da duniya gas akai, da yawan zafin jiki a Kelvin, da kuma matsa lamba a Pascals da girma a cikin m ^3. Saboda wannan adadin data kurakurai a cikin lissafi na m, amma ya kamata a lura da cewa Jadawalin Mendeleev-Clapeyron aiki ne kawai don gaseous abubuwa.

A kwayoyin nauyi na maras tabbas mahadi za a iya ƙaddara da taro spectrometry ko gas chromatography yin amfani da iskar gas nauyi Martin. A talakawan darajar wannan index ga polymeric kayan da wani babban Polymerization mataki da aka lasafta bisa laákari da rheological halaye da kuma kaddarorin su da mafita (msl, danko, ko haske watsi ikon).

Don sanin abin da kwayoyin nauyi?

The lamba darajar wannan yawa da ake amfani da su gane daban-daban sinadaran mahadi da kuma gane mutum nucleotides a cikin gwajin abu. Bayan da sinadaran nuna alama ne sau da yawa m da bincike da kuma kira na macromolecular mahadi, wato Properties dogara ne a kan wannan siga.
