The correct answer is B. 50 feet divided by 3.28084 feet (1 meter).
Small peak at 3000large peak at 1685F: it contains two benzene rings that is connected by a bunch of carbons and ketone-Explanation: The spectrum shows a stretching absorption consistent with a ketone functional group: carbonyl C=O stretching at ~1685 cm-1. (An aldehyde, by contrast, would also show a ~2700 cm-1 absorption for the carbonyl C-H stretch.) The C=O stretching frequency is consistent with an aromatic ketone, such as in compound F (1,4-diphenyl-1,4-butanedione). In contrast, an aliphatic ketone absorbs at higher energy (~1710 cm-1). The spectrum also shows the typical ~1600 & ~1500 cm-1 absorptions of a phenyl group.
Answer:
Water and Salt are the products of simplest types of acid-base reactions.
Examples:
Base Acid Salt Water
NaOH + HCl → NaCl + H₂O
2 NaOH + H₂SO₄ → Na₂SO₄ + 2 H₂O
NaOH + CH₃CO₂H → CH₃COONa + H₂O
In all theses simple reactions the base (i.e. OH⁻) abstracts proton from the acid and forming a conjugate base with negative charge. Thus the negative charged conjugate base forms a salt with positively charged sodium ions.
