Respuesta:

CH4 + 2O2 = CO2 + 2H2O

4 H 4

4 O 4

1 C 1

H = 1 × 4 = 4g

O = 16 × 4 = 64g + = 80g

C = 12 × 1 = 12g

N2O5 + H2O = 2HNO3

2 H 2

6 O 6

2 N 2

H = 1 × 2 = 2g

O = 16 × 6 = 96g + = 126 g

N = 14 × 2 = 28g

C5H12 + 8O2 = 5CO2 + 6H2O

12 H 12

16 O 16

5 C 5

H = 1 × 12 = 12g

O = 16 × 16 = 256g + = 328g

C = 12 × 5 = 60g

2C2H6 + 7O2 = 4CO2 + 6H2O

12 H 12

14 O 14

4 C 4

H = 1 × 12 = 12g

O = 16 × 14 = 224g + = 284g

C = 12 × 4 = 48g
