Question

SiH4+O2Help)Очень нужно

Answer 1

Ну раз очень нужно) 
SiH4+2O2= SiO2+2H2O

Нужно) это реакция обмена.
К кремний(Si) прибавляется кислород(О2),а к водороду(H2) кислород (О2)
образуется = окид кремния и вода.
осталось только уравнять 
 SiH4+2O2 = SiO2+2H2O

Answer 2

SiH4 + O2 Reaction

The reaction between SiH4 (silane) and O2 (oxygen) can be represented as follows:

SiH4 + 2O2 → SiO2 + 2H2O [[7]](https://www.chem.msu.su/rus/school/svitanko-2012/fulltext.pdf)

In this reaction, silane (SiH4) reacts with oxygen (O2) to produce silicon dioxide (SiO2) and water (H2O).

Explanation

Silane (SiH4) is a colorless, flammable gas that consists of silicon (Si) and hydrogen (H) atoms. Oxygen (O2) is a diatomic molecule that is essential for combustion and supports various chemical reactions.

When SiH4 reacts with O2, the silicon (Si) atom in SiH4 combines with two oxygen (O) atoms from O2 to form silicon dioxide (SiO2). At the same time, the four hydrogen (H) atoms in SiH4 combine with one oxygen (O) atom from O2 to form water (H2O). The balanced equation for this reaction shows that two molecules of O2 are required to react with one molecule of SiH4.

Balanced Equation

The balanced equation for the reaction between SiH4 and O2 is:

SiH4 + 2O2 → SiO2 + 2H2O This equation shows that one molecule of SiH4 reacts with two molecules of O2 to produce one molecule of SiO2 and two molecules of H2O.

Conclusion

In summary, when SiH4 reacts with O2, it forms SiO2 and H2O according to the balanced equation: SiH4 + 2O2 → SiO2 + 2H2O
