Question

a) NaClO3 -> NaCl + O2------------------------DESCOMPOSICION b) HNO3 +Fe -> H2 + Fe (NO3)2------------SIMPLE SUSTITUCION c) Kl + Pb (NO3)2 -> Pbl2 + KNO3--------DOBLE SUSTITUCION d) C + O2 -> CO2-----------------------COMBINACION o SINTESIS e) Ca(HCO3)2 -> CaCO3 + CO2 + H2O--no estoy seguro pero en todo caso DESCOMPOSICION

Answer 1

a) 2 NaClO₃= 2 NaCl + 3 O₂ ( decomposition )

b) 2 HNO₃ + Fe = H₂ + Fe(NO₃)₂ ( single replacement )

c) 2 Kl + Pb(NO₃)₂ -> Pbl₂ + 2 KNO₃ ( double replacement )

d) C + O₂ -> CO₂ ( synthesis )

e) Ca(HCO₃)₂ = CaCO₃ + CO₂ + H₂O ( decomposition)

hope this helps!
