Students have asked these similar questions
student found a bottle of unknown origin in the basement of an
"CAUTION—contains С₁H₁O.” No other
A
old house. The bottle was labelled
information was given, but inside the bottle were some white crystals.
The student took the bottle to a chemistry laboratory, where she analyzed the
crystals with the help of the laboratory staff. C₁2H₁6O reacted with Br₂ in CCl4
adding one mole of Br, and forming C₁₂H₁OB2₂.
When a sample of C₁₂H₂O was reacted with O3 followed by Zn/H₂O, two
different samples, J and K, were obtained. Compound J had a molecular formula
of C.HgO₂, and its NMR is shown below.
Compound K had a molecular formula of C₂H₂O, and it could be oxidized to
compound L, with a molecular formula of C₂H₂O₂. The IR spectrum of L showed
a very wide, strong band centred around 3000 cm*¹. The NMR spectrum of L
showed only two different absorptions: a doublet (6H) at 0.9 ppm and a septet
(1H) at 3.6 ppm. There was also a singlet (1H) off the scale at 11.8 ppm.

A sample of iron weighing 15.0 g was heated with potassium chlorate (KCIO3) in an evacuated container. The oxygen generated from the
decomposition of KCIO3 converted some of the Fe to Fe2Oe. If the combined mass of Fe and Fe203 was 17.9 g, calculate the mass of Fe203
formed and the mass of KCIO3 decomposed. Please show your work for credit and comment on another students such as asking a question or
pointing the student in the right direction.

- • Sucrose: C12 H22O11 • Copper (I) Chloride: CuCl • lodine: I2 • Potassium lodide: KI Our goal is to try to find a pattern for which compounds conduct electricity when dissolved in water, and which don't. One hint is to look for patterns in which kinds of atoms form substances that conduct when dissolved, and which kinds of atoms form substances that don't conduct when dissolved.
