Question

I
identify balance chemical equation from the following
1) C+O2 ........Co2
2) H2+O2....... H2O
3) 2Pbo+C.......Pb+ Co2
4) Fe2o3+ 2Al .......Al2co3+2Fe
​

Answer 1

Answer:

1 c + o2 = co2 is the correct answer

Explaination:

because c = 1 and o = 2 on the left side and c = 1 and o = 2 on right side

so it's balanced

Answer 2

Answer:

first equation is balanced chemical equation

Explanation:

C + O2......CO2
