b)Na2O + H2O --------->NaOH

c)Cu + AgNo3----------->Cu(No3)2 + Ag

d)K + H2O---------->KOH +H2

Answer 1

a, \(2Fe+3Cl_2\underrightarrow{t^o}2FeCl_3\)

b, \(Na_2O+H_2O\rightarrow2NaOH\)

c, \(Cu+2AgNO_3\rightarrow Cu\left(NO_3\right)_2+2Ag\)

d, \(2K+2H_2O\rightarrow2KOH+H_2\)

Answer 2

\(a)2Fe+3Cl_2\underrightarrow{t^o}2FeCl_3\) 

\(b)Na_2O+H_2O\rightarrow2NaOH\)

\(c)Cu+2AgNO_3\rightarrow Cu\left(NO_3\right)_2+2Ag\)

\(d)2K+2H_2O\rightarrow2KOH+H_2\uparrow\)
