Yini tinzuzo ethanol njengemkhicito wekubulala emagciwane?
Imikhicito Yekubulala Tigciwane Tjwala lobunencenye yevolumu lengetulu kwa 99.5% bubitwa ngekutsi yi ethanol lephelele. Ku biology, isetjentiswa ngoba imibala kuma chloroplasts iyancibilika etinhlayiya letiphilako letifana ne ethanol lephelele (noma i-acetone), ngako iethanol lephelele ingasetjentiswa kukhipha lemibala. 95% tjwala busetjentiswa...Fundza kabanti -
