Question

Write word equations for the following skeletal equations:

(a) KClO3 → KCl + O2

(b) Zn + HCl → ZnCl2 + H2

(c)FeCl2 + Cl2 → FeCl3

(d) CO + O2 → CO2

(e) Ca + O2 → CaO

(f) Na + O2 → Na2O

(g) NaOH + H2SO4 → Na2SO4 + H2O

(h) AgBr → Ag + Br2

(i) KNO2 → KNO2 + O2

Answer 1

(a) 2KClO3 → 2KCl + O2

(b) Zn + 2HCl → ZnCl2 + H2

(c) 2FeCl2 + Cl2 → 2FeCl3

(d) 2CO + O2 → 2CO2

(e) 2Ca + O2 → 2CaO

(f) 4Na + O2 → 2Na2O

(g) 2NaOH + H2SO4 → Na2SO4 + 2H2O

(h) 2AgBr → 2Ag + Br2

(i) 2KNO2 → 2KNO2 + O2
