Answer to Question #155158 in General Chemistry for Alex

Question

Select the coefficients using the electronic balance method:

a) Cu(NO3)2→ CuO+NO2+O2

b) FeCl3 +KI →FeCl2+I2+KCl

c) KOH+Cl2 → KClO3+KCl+H20

d) CH4+O2+NH3 → HCN+H2O

Answer 1

a)

2 Cu ( NO₃ ) ₂ = 2CuO + 4 NO₂ + O₂ .

b )

2FeCl₃ + 2KI = 2FeCl₂ + I₂ + 2KCl .

c )

12KOH + 6Cl₂ = 10KCl + 2KClO₃ + 6H₂O

d )

2CH₄ + 3O₂ + 2NH₃ = 2HCN + 6H₂O
