Question

2. Balance the following chemical equations with steps a) NaOH + H2SO4→ Na2SO4 + H2O b) Hg (NO3)2 + KI → Hg I2 +KNO3 c) H2 + O2→ H2O d) KClO3→KCl + O2 e) C3H8 + O2→ CO2 + H2O

Answer 1

A- 2NaOH + H2SO4=Na2SO4 +2H2O.
B- Hg (NO3)2 +2KI=HgI2 + 2KNO3.
C-2H2+O2= 2H2O.
D-2KClO3=2KCl+3O2.
E-C3H8+5O2=3CO2+4H2O.
