Re: Electrophilic Addition vs. Nucleophilic Substitution
Bimolecular nucleophilic substitution is a one-step reaction because the nucleophile is replacing the leaving group in one step. Unimolecular nucleophilic substitution, however, is a two-step reaction where the leaving group detaches followed by the nucleophile replacing it.

Re: Naming alkenes
Yes, when the alkene carbon chain has four or more carbon atoms then the position of the double bond needs to be given in the name.

Re: Midterm 2014 Number 8
I think it is because it is asking for the value of Ka for HF, so you want to get the overall rxn as HF = H+ + F-.

Re: work
In this case, the battery is the system. Since the system is doing work, work is negative.

Re: How to draw a heating curve?
The horizontal lines are the phase changes and the slopes are based off of the heat capacities. The x axis is the amount of heat inputted and the y axis is the temperature.

Re: Expansion work
Yes it means that the volume doesn't change. Instead, work is done by heat.

Re: bomb calorimeter
The combustion of glucose in a bomb calorimeter is isolated because no matter or energy can be exchanged with the environment.

Re: Exothermic vs. Endothermic
I believe this is an endothermic reaction because the ice pack takes up heat while the knee along with the surroundings will cool down.

Re: Metal oxides
Yes.
MO +H2O = MOH
For example:
CaO + H2O = Ca(OH)2
MO +H2O = MOH
For example:
CaO + H2O = Ca(OH)2

Re: Adding "-ate" to a metal
You add "-ate" to the TM when the complex has a negative charge.

Re: Lewis Structure of NO3-
Because Oxygen is not in the 3rd period or below. Therefore it cannot hold more than 8 valence electrons and has to abide to the octet rule.

Re: Polarity
Isn't there some uncertainty to this? You can't say it is nonpolar because you don't know whether the 2 F atoms or the 2 Cl atoms are across from each other in order for them to cancel out.

Re: Finding wavelenght when speed is given [ENDORSED]
Shouldn't it be 1.3 x 10^-31 m? Because if you convert 1.5 grams to kilograms, it becomes 1.5 x 10^-3 kg.

Re: Shorter vs Longer Wavelength
The smaller the wavelength, the larger the energy. The larger the wavelength, the smaller the energy.

Re: Chromatography?
Chromatography is a technique used to separate the different components of a mixture. This technique relies on the ability of different phases to absorb substances to different extents.
