Question

Расставьте все как нужно)) Cr+O2= Cl2+O2=Cl2O CH4+O2= C3H8+O2= Mn+O2=

Answer 1

4Cr+3O2=2Cr2O3

2Cl2+O2=2Cl2O

CH4+2O2=CO2+2H2O

C3H8+5O2=3CO2+4H2O

Mn+O2=MnO2

Answer 2

To balance the chemical equations, we need to ensure that the same number of atoms of each element appear on both sides of the equation. Here are the balanced chemical equations:

1. Cr + O2 = Cr2O3 (balanced)
2. Cl2 + O2 = Cl2O7 (balanced)
3. CH4 + 2O2 = CO2 + 2H2O (balanced)
4. C3H8 + 5O2 = 3CO2 + 4H2O (balanced)
5. Mn + O2 = MnO2 (balanced)
