An oxide X in the normal form is almost non-reactive due to very high X - O bond enthalpy. It resists the attack by halogens, hydrogen and most of acids and metals even at elevated temperature. It is only attacked by HF and NaOH. The oxide X is.

1.	An oxide X in the normal form is almost non-reactive due to very high X - O bond enthalpy. It resists the attack by halogens, hydrogen and most of acids and metals even at elevated temperature. It is only attacked by HF and NaOH. The oxide X is.
Answer» `SiO_(2)` `CO_(2)` `SnO_(2)` `PbO_(2)` SOLUTION :`SiO_(2)` is attacked by HF and NaOH but not by chemicals under NORMAL conditions
