Question

e) CaO+…. ---> Ca(OH)₂

f) SO2 + H2O --->  ...

g)... + H20 ---> H2SO4

h) .. + H2O ---> H3PO4

k) Sat (III) clorua + Canxi hiđroxit-> Sắt (III) hiđroxit + Canxi clorua

1) Kali sunfit+Đồng (II) nitrat =>Kali nitrat + Đồng (II) sunfit

Answer 1

\(CaO+H_2O\rightarrow Ca\left(OH\right)_2\\ f,SO_2+H_2O\rightarrow H_2SO_3\\ SO_3+H_2O\rightarrow H_2SO_4\\ P_2O_5+3H_2O\rightarrow2H_3PO_4\\ 2FeCl_3+3Ca\left(OH\right)_2\rightarrow2Fe\left(OH\right)_3+3CaCl_2\\ K_2SO_3+Cu\left(NO_3\right)_2\rightarrow2KNO_3+CuSO_3\)

Answer 2

e) CaO+…H2O. ---> Ca(OH)₂

f) SO2 + H2O --->  ...H2SO3

g)..SO3. + H20 ---> H2SO4

h) .. P2O5+ 3H2O ---> 2H3PO4

k) Sat (III) clorua + Canxi hiđroxit-> Sắt (III) hiđroxit + Canxi clorua

2FeCl3+3Ca(OH)2->2Fe(OH)3+3CaCl2

1) Kali sunfit+Đồng (II) nitrat =>Kali nitrat + Đồng (II) sunfit

K2SO3+Cu(NO3)2->2KNO3+CuSO3

Answer 3

\(CaO+H_2O\rightarrow Ca\left(OH\right)_2\\ SO_2+H_2O\rightarrow H_2SO_3\\ SO_3+H_2O\rightarrow H_2SO_4\\ P_2O_5+3H_2O\underrightarrow{t^o}2H_3PO_4\) 
\(2FeCl_3+3Ca\left(OH\right)_2\rightarrow2Fe\left(OH\right)_3+3CaCl_2\)
\(K_2SO_3+Cu\left(NO_3\right)_2\rightarrow2KNO_3+CuSO_3\)
