urea
Yog li ntawd, Wohler tau tsim urea li cas?
Hauv qhov kev sim no, Wohler yog sim ua kom ammonia cyanate, tab sis thaum ammonia cyanate tsim nyob rau hauv cov mob no nws decomposed thiab ces tsim. urea . Muaj peb kauj ruam nyob rau hauv cov tshuaj tiv thaiv: ntsev rearrangement, tsim ammonium cyanate. Ammonium decomposes tsim ammonia thiab cyanic acid.
Vim li cas Wohlers nrhiav tau ua rau kev txhim kho ntawm cov organic chemistry? Frederich Wohler yog ib kws tshuaj leej twg cais ntshiab txhuas. Nws yog suav nrog ntau kws tshuaj ua leej txiv organic chemistry vim nws tau qhia tias koj tuaj yeem noj cov ntxhia tsis muaj sia (ammonium cyanate) thiab ua ib yam khoom uas yog tam sim no nyob rau hauv cov tsiaj txhu (urea los ntawm cov zis).
Ntawm no, dab tsi yog qhov synthesis ntawm urea?
Vitalism thiab synthesis ntawm urea . Xyoo 1828, Friedrich Wöhler, tus kws kho mob German thiab kws kho mob los ntawm kev cob qhia, tau luam tawm ib daim ntawv uas piav qhia txog kev tsim cov tshuaj. urea , paub txij li xyoo 1773 los ua ib feem tseem ceeb ntawm cov zis mammalian, los ntawm kev sib txuas cyanic acid thiab ammonium hauv vitro.
Leej twg yog leej txiv ntawm organic chemistry?
Friedrich Wöhler

Dab tsi yog qhov cuab yeej tsim nyog ua ntej kev tshawb xav ntawm tes yuav tsim tau?
Lub microscope yog tsim nyog ua ntej qhov kev xav ntawm tes yuav tsim. Peb tus kws tshawb fawb twg tau txais qhab nia rau cov pov thawj ncaj qha ua rau txoj kev xav ntawm tes? Matthias Schleiden, Theodor Schwann, thiab Rudolph Virchow peb yog txhua tus kws tshawb fawb uas tau pab txhawb txoj kev xav ntawm tes
LEEJ TWG ceeb toom FDR cov neeg German tau tsim riam phom atomic thiab US xav tau ua ib yam?
Xya caum tsib xyoos dhau los, Hungarian-American physicist Leo Szilard tau sau ib tsab ntawv mus rau Tebchaws Meskas Thawj Tswj Hwm Franklin Roosevelt qhia kev txhawj xeeb tias cov kws tshawb fawb German yuav sai sai no qhib qhov zais cia los tsim thawj lub foob pob tawg
Dab tsi yog qhov txawv ntawm kev xaiv khoom tsim thiab kev tsim noob caj noob ces?
Artificial xaiv xaiv rau cov yam ntxwv uas twb muaj nyob rau hauv ib hom, whereas genetic engineering tsim cov yam ntxwv tshiab. Hauv kev xaiv dag, cov kws tshawb fawb yug tsuas yog cov tib neeg uas xav tau qhov zoo. Los ntawm kev xaiv kev yug me nyuam, cov kws tshawb fawb muaj peev xwm hloov cov cwj pwm hauv cov neeg. Evolution tau tshwm sim
Lub chaw tsim hluav taws xob nuclear tsim tau li cas?
Nuclear fission tsim cua sov Reactors siv uranium rau nuclear roj. Cov uranium tau ua tiav rau hauv cov me me ceramic pellets thiab muab tso ua ke rau hauv cov raj hlau kaw hu ua roj rods. Lub tshav kub tsim los ntawm fission hloov cov dej mus rau hauv chav, uas tig lub turbine los tsim hluav taws xob tsis muaj carbon
Henri Becquerel nrhiav tau dab tsi uas ua rau nws tau txais 1903 Nobel nqi zog Nws nrhiav tau dab tsi txog lub caij uranium?
Teb: Henri Becquerel tau txais ib nrab ntawm qhov khoom plig rau nws qhov kev tshawb pom ntawm cov hluav taws xob tsis zoo. Teb: Marie Curie tau kawm txog cov hluav taws xob ntawm tag nrho cov tebchaw uas muaj cov xov tooj cua paub, suav nrog uranium thiab thorium, uas nws tom qab pom kuj tseem muaj xov tooj cua
