Spontaneous combustion prevention of iron sulfide, must accomplish the following several points: one is the container when in use, the operator should be strictly in accordance with the procedures, constantly keep container within the normal level; the second is when the container to temporarily stop production, and the material and released. When the two equations are added together, the AgNO 3 (s) cancels out as does 1 ⁄ 2 O 2 (g) and we are left with the formation equation for AgNO 2 (s), the equation given in step 2.

Now, before you you need to double check to ensure that there is the same number of elements on both side. For example, if one sides has 2 Iron, then the other side needs to have two iron as-well. So ensure that the ratio is equal on both sides The combustion behavior of pulverized sponge iron (PSI) burning in exhausts of methane/air flames was investigated by Tóth et al. using high-magnification shadowgraphy. They observed that PSI combusts heterogeneously, with most of the particle mass converting to an intact, solid oxide For complete combustion, carbon becomes CO₂ and hydrogen becomes H₂O: 8 C + 16 O → 8 CO₂. 18 H + 9 O → 9 H₂O. Adding together: C₈H₁₈ + 25 O → 8 CO₂ + 9 H₂O. But, the substances in chemical equations must always be shown in the molecular form, not as atoms, therefore, and since oxygen comes in the form of a diatomic.
