1 Balance the following equations 1 point a Na2CO3 HCl NaCl

1. Balance the following equations: (1 point) a. Na2CO3 + HCl NaCl + CO2 + H2O

b. Cl2 + KOH KCl + KClO3 + HCl

c. Fe(OH)2 + O2 + H2O Fe(OH)3

d. FeS + HCl FeCl2 + H2S

Solution

a) Balanced equation =

Na₂CO₃ + 2 HCl = 2 NaCl + CO₂ + H₂O

b) 3 Cl₂ + 3 KOH = 2 KCl + KClO₃ + 3 HCl
c) 4 Fe(OH)₂ + O₂ + 2 H₂O = 4 Fe(OH)₃

_d) FeS + 2 HCl = FeCl₂ + H₂S
