Question

Realize o balanceamento das equações abaixo e indique a resposta que caracteriza corretamente os conjuntos de coeficientes:

C4H10 + O2 --> CO2 + H2O

C3H8O2 + O2 --> CO2 + H2O

NO + NH3 --> N2 + H2O

P4 + O2 --> P4O10

FeCl3 + O2 --> Fe2O3 + Cl2

FeTiO3 + C + Cl2 --> FeCl3 + TiCl4 + CO2
Escolha uma:
a. [3,17,9,19]; [1,3,4,3]; [6,4,5,6]; [1,4,1]; [4,3,2,65]; [1,3,7,2,2,3]
b. [2,13,8,10]; [1,4,3,4]; [6,4,5,6]; [1,5,1]; [4,3,2,6]; [2,3,7,2,2,3]
c. [3,17,9,19]; [1,4,3,4]; [6,4,5,6]; [1,6,1]; [4,1,1,6]; [1,1,5,1,2,3]
d. [2,13,8,10]; [1,4,3,4]; [6,4,6,5]; [2,9,2]; [4,3,2,6]; [2,2,7,2,3,3]

Answer 1

(2)C4H10 + (13)O2 >  (8)CO2 + (10)H2O
(1)C3H8O2 + (4)O2 >   (3)CO2 + (4)H2O
(6)NO + (4)NH3 >  (5)N2 (6)H20
P4 + (5)O2 > P4O10
(4)FeCl3 + (3)O2 > (2)Fe2O3 +  (6)Cl2
(2)FeTiO3 + (3)C + (7)Cl2 > (2)FeCl3 + (2)TiCl4 + (3)CO2

RESPOSTA B
