Thermal decomposition of Li[IF4] givesALiF + IF3 BLiF + LiI + F2 + I2 CLil + 2F2 DLi + I2 + F2
Question
Thermal decomposition of Li[IF4] gives:
- A) LiF + IF3
- B) LiF + LiI + F2 + I2
- C) LiI + 2F2
- D) Li + I2 + F2
Solution
The thermal decomposition of Li[IF4] would result in the formation of LiF and IF3. Therefore, the correct answer is A: LiF + IF3.
Here's a step-by-step breakdown:
-
Identify the reactant: The reactant in this reaction is Li[IF4].
-
Predict the products: When Li[IF4] is heated, it breaks down into simpler substances. Lithium (Li) will likely bond with one of the fluorine (F) atoms because lithium is a metal and fluorine is a non-metal, and metals tend to donate electrons to non-metals in chemical reactions. This forms LiF. The remaining IF3 molecule is left as is.
-
Write the balanced chemical equation: The balanced chemical equation for this reaction is Li[IF4] -> LiF + IF3.
So, the correct answer is A: LiF + IF3.
