Answer (1)
The problem states that silicon dioxide reacts with hydrofluoric acid to produce silicon tetrafluoride and water.
Identify the products of the reaction.
The products are silicon tetrafluoride ( S i F 4 ) and water ( H 2 O ).
Therefore, the final answer is S i F 4 + H 2 O .
Explanation
Identifying Reactants and Products The problem states that silicon dioxide ( S i O 2 ) reacts with hydrofluoric acid ( H F ) to produce silicon tetrafluoride ( S i F 4 ) and water ( H 2 O ). We need to identify the products of this reaction.
Determining the Products The problem explicitly states that the products are silicon tetrafluoride ( S i F 4 ) and water ( H 2 O ).
Final Answer Therefore, the products of the reaction are S i F 4 and H 2 O .
Examples
In the manufacturing of semiconductors, hydrofluoric acid is used to etch silicon dioxide layers. The reaction produces silicon tetrafluoride and water as byproducts. Understanding this reaction is crucial for controlling the etching process and managing the waste products in semiconductor fabrication.
