Question

1. Написати рівняння хімічних реакцій горіння таких речовин S,Si2H6

Answer 1

S + O₂ → SO₂

2Si₂H₆ + 7O₂ → 4SiO₂ + 6H₂O

Answer 2

I can help you with your chemistry question.

1. To write the equations of combustion reactions of such substances as S and Si2H6, you need to know the products of these reactions and balance the coefficients of the reactants and products. The products of combustion reactions are usually oxides of the elements involved. For example, sulfur (S) reacts with oxygen (O2) to form sulfur dioxide (SO2), and silicon hydride (Si2H6) reacts with oxygen to form silicon dioxide (SiO2) and water (H2O). The balanced equations are:

$$S + O_2 \rightarrow SO_2$$ $$2Si_2H_6 + 7O_2 \rightarrow 4SiO_2 + 6H_2O$$

You can check the validity of these equations by counting the number of atoms of each element on both sides of the arrow. They should be equal. You can also use online tools to balance chemical equations, such as [this one](https://chemequations.com/ru/).
