Answer 1

Step-by-step explanation:

II.C.12 Hydrogen Fluoride–Tantalum Pentafluoride

HF:TaF5 is a catalyst for various hydrocarbon conversions of practical importance. In contrast to antimony pentafluoride, tantalum pentafluoride is stable in a reducing environment. The HF:TaF5 superacid system has attracted attention mainly through the studies concerning alkane alkylation and aromatic protonation. Generally, heterogeneous mixtures such as 10:1 and 30:1 HF:TaF5 have been used because of the low solubility of TaF5 in HF (0.9% at 19 °C and 0.6% at 0 °C). For this reason, acidity measurements have been limited to very dilute solutions, and an H0 value of −18.85 has been found for the 0.6% solution. Both electrochemical studies and aromatic protonation studies indicate that the HF:TaF5 system is a weaker superacid than HF:SbF5.

Answer 2

Answer:

Milder forms of pain may be relieved by over-the-counter medications such as Tylenol (acetaminophen) or nonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin, ibuprofen, and naproxen.
