Organic chemistry is difficult. Those who study it have alkynes of trouble.

The prefixes you ignore when alphabetizing are di-, tri-, tetra-...
Iso and neo are part of the group name so they are alphabetized.

I'm not quite sure what example you are talking about but you can tell it is an alkyne because of the triple bond. Also, you can tell that it is an alkyne because of the molecular formula C(n)H(2n-2) Are you talking about the structure? If so, you would have something like C /// \ H-C C-H-H-H (The f...

Resonance structures are used instead of single Lewis structures to better show the delocalized electrons in a molecule. For resonance structures, we want to minimize the charge so we want to minimize charge separation. Charge separation is basically the amount of positive and negative charges in a ...

Midterm Winter 2016
The following reaction is used in the acidic solution in the Breathalyzer test to determine the level of alcohol in the blood:

H+(aq) + (Cr2O7)-2(aq) + C2H5OH(aq) ---> (Cr)3+(aq) + C2H4O(aq) + H2O(l)

I need help figuring out how to get a balanced redox equation

In addition, oxygen can even have a -.5 charge in superoxides.

Spontaneous reactions are usually exergonic, meaning that energy flows from the system to the surroundings. The energy released, free energy, can be used to do work.

I got 245.4 kJ
I'm not too sure of the limiting reagent though
