In this study, the effect of N-acetylglucosamine on the metabolome of Streptomyces sp. RM66 was investigated using three actinomycetes media (ISP2, M1 and MA). In total, twelve extracts were produced using solid and liquid fermentation approaches. Liquid chromatography-high resolution tandem mass ...

解:除去\rm{NaNO_{3}}溶液中混有的\rm{AgNO_{3}},则\rm{c(Ag^{+})}相同,生成沉淀时,\rm{c(NaCl)= \dfrac {1.8×10^{-10}}{c(Ag^{+})}mol/L},\rm{c(NaBr)= \dfrac {4.9×10^{-13}}{c(Ag^{+})}mol/L},\rm{c(NaI)= \dfrac {1.0×10^{-16}}{c(Ag^{+})}...
解:\(\rm{Mn^{2+}}\)沉淀较为完全时的浓度\(\rm{\leqslant 1×10^{-5}mol/L}\),已知\(\rm{K_{sp}=c(Mn^{2+})×c^{2}(OH^{-})}\), 则\(\rm{c(OH^{-})\geqslant \sqrt { \dfrac {K_{sp}}{c(Mn^{2+})}}= \sqrt { \dfrac {2×10^{-13}}{1\times 10...

由\rm{K_{sp}(AgCl)=1.8×10^{-10}},\rm{K_{sp}(AgBr)=5×10^{-13}},可知在\rm{AgCl}和\rm{AgBr}两饱和溶液中,\rm{c(Cl^{-}) > c(Br^{-})},向两饱和溶液中,加入\rm{AgNO_{3}},\rm{AgCl}与\rm{AgBr}的溶解平衡向左移动,但是饱和溶液中\rm{AgBr}的溶解度更小,所以...
Nicknamed “The American Dream,” the 333 SP project was particularly appealing to the higher-ups in Maranello, since Ferrari’s sports car racing effort was aimed at the key North American market, because there were no F1 races in the United States at that time. Instead, there was the IMS...
