(4)由题意可知,7.84 g摩尔盐中含有H2O的质量为7.84 g-5.68 g=2.16 g,则n(H2O)=0.12 mol;NH3的质量为0.68 g,则n(NH4+)=0.04 mol;加入适量3%的H2O2溶液,充分振荡后滤出沉淀,洗净、干燥、灼烧后,得到Fe2O3,测得其质量为1.6 g,则n(Fe2O3)=0.01 mol,则7.84 g摩尔盐中含有的n(Fe2+)=0.02 mol,...

To confirm the binding activity, the F2 region was divided into f3oouf r22 small fragments (F2-1 to F2-4) that were further tested in a Y1H assay (Figure 1A). Here, LacZ was used as a reporter gene. We found that STOP1 could only bind to the F2 and F2- 2Ff2ra-2gmfraegnmtse...
(1)加水稀释,一水合氨的电离平衡向右移动,即电离被促进,电离出更多的氢氧根,故将0.10mol/L NH3H2O溶液稀释10倍,则稀释后的溶液中c(OH﹣)大于原来的十分之一,故答案为:大于。 (2)根据电荷守恒可以知道:c(OH﹣)+c(CH3COO﹣)= c(H+)+ c(NH4+),0.10mol/L CH3COONH4溶液的pH=7,即c(OH﹣)=c(H+)...
