Answer 1

Answer:

a] 4P + O2 + P205

b] NaO + H2O + NaOH

dj Fe + H2O = Fe 04 + H2

e CaO + HC> CaCl2 + H2O

g] Al + H2O → Al2O3 + H2 h] Al + H2SO4 → Al2(SO4)3 + H2

il C + H2SO4 → CO2 + H2O + SO2 k] Pb304 → PbO + O2

m] NO + O2 + NO2

n] ZnS + O2 → ZnO + SO2

p] ZnO + NaOH → Na ZnO2 + H2O q] HS + Cl2 → S + HCI

s] Fe2O3 + CO → Fe + CO2 t] KHCO3 → K2CO3 + H2O + CO2
