Final answer:
The statement that HCl is formed as a result of the reaction is true, as indicated by the provided balanced chemical equation SiCl₄ + 2 H₂O → SiO₂ + 4 HCl.
Step-by-step explanation:
Based on the balanced chemical equation provided, SiCl₄ + 2 H₂O → SiO₂ + 4 HCl, the statement "HCl is formed as a result of the reaction" is true. In this reaction, silicon tetrachloride (SiCl₄) reacts with water (H₂O) to produce silicon dioxide (SiO₂) and hydrochloric acid (HCl). When balancing chemical equations, it is essential to ensure that there are equal numbers of each type of atom on both sides of the equation. Equations like H₂ + Cl₂ → 2 HCl provide examples of simple combinations resulting in the formation of hydrochloric acid.
Moreover, in chemical reactions such as SiO2 (s) + 2C(s) + 2Cl2(g) → SiCl4 (g) + 2CO(g), silicon tetrachloride is generated SiCl4, further illustrating various types of reactions where balancing is crucial.
