Answer

4HF +SiO$_{2}$ --> SiF$_{4}$ +2H$_{2}$O

Work Step by Step

Use prefixes and naming rules to find the chemical formulas from the word descriptions. Then, write the reaction HF +SO$_{2}$ --> SiF$_{4}$ +H$_{2}$O. This reaction is not balanced. Balance it by first balancing the fluorine atoms, then the hydrogen atoms. After doing that we find that the oxygen and silicon atoms are also balanced so we are done.
