SCIENCE QUESTIONS （会做的要帮忙!
1、what family or group are the halogens in name all elements in the halogen family.
2/what effect does silver nitrate solution have upon each of the halide salt solutions does a chemical reaction occur for each
3/write the chemical equations for the reaction of silver nitrate with each of the halide salt solution ...
4/what kind of chemical reaction occured (systhesis/decomposition/or replacement)
5/what effect does ammonium hydroxide have on each of the precipitates does a chemical reaction occur for each
6/write the chemical equations for any reactions that occur .

Answer 1

1.问的是卤素.是VIIA族元素
氟F氯Cl溴Br碘I砹At
2.问的是AgNO3是否会与卤盐反应
除了F-,Ag+会与X-生成沉淀.
3.AgNO3+NaCl=AgCl↓+NaNO3
AgNO3+NaBr=AgBr↓+NaNO3
AgNO3+NaI=AgI↓+NaNO3
AgNO3+NaAt=AgAt↓+NaNO3
4.replacement复分解反应
5.你这里指氨水和什么反应导致析出?如果是和前面生成的沉淀的话
那么只有AgCl溶解,其余得都不溶解.
6.AgCl+2NH3·H2O=[Ag(NH3)2]Cl+2H2O
