6.A solution of aluminum chloride and bromine gas are produced when a solution of aluminum bromide and chlorine gas are combined
7.Potassium metal and chlorine gas combine to form potassium chloride
8.Hydrogen gas and nitrogen monoxide react to form water nitrogen gas

Answer 1

2,是水的蒸馏
3，置换反应，Cu+2AgNO3=Cu（NO3)2+2Ag
4，氧化反应，C6H12O6+6O2=点燃=6CO2+6H2O
5，Pb(NO3)2+Zn=Pb+Zn(NO3)2,
6， AlCl3 + 3H2O =加热= Al(OH)3 + 3HCl气体
Br2+H2O=HBr+HBrO，Al(OH)3 +3HBr=AlBr3+3H2O
7，2K+Cl2=2KCl
8，2NO+2H2=N2+2H2O
