Answer:
The most appropriate structure given the sparse spectral data is<u><em> 4-acetyl benzoic acid (see attached).</em></u>
Explanation:
It is difficult to accurately elucidate the structure of this compound without its chemical formula. But from the 1H NMR spectral data shows a total of 8 hydrogen atoms:
- 12.71 (1H. s) - confirms presence of carboxylic acid proton, C=O-OH
- 8.04 (2H, d) - confirms aromatic hydrogen
- 7.30 (2H, d) - confirms aromatic hydrogen
- 2.41 (3H,s) - confirms C=C hydrogen or ketone O=C-RCH3
The attached files show the structure and the neighboring hydrogen atoms.

Answer:
21.3 g of CaCl₂ are produced in this reaction
Explanation:
Reaction is this:
CaCO₃ + 2HCl → CaCl₂ + H₂CO₃
Molar mass salt : 100.08 g/m
Molar mass acid: 36.45 g/m
We have 28 g / 100.08 g/m = 0.279 moles of CaCO₃
We have 14 g / 36.45 g/m = 0.384 moles of HCl
Ratio is 1:2, so 0.279 moles of salt will need the double of moles of acid.
0.279 . 2 = 0.558 moles of acid needed. (I have only 0.384 moles, so the acid is the limiting reactant)
0.384 moles of HCl produce the half of moles of CaCl₂ (This ratio is 1:2) --> 0.192 moles
Molar mass of CaCl₂ = 110.98 g/m
Mol . molar mass = mass → 0.192 m . 110.98 g/m = 21.3 g
Answer:
Decompositon
Explanation:
Sodium chlorate → Sodium Chloride + Oxygen
Sodium chlorate is reactant.
Sodium chloride + Oxygen is the product.
