Re: Combining IUPAC with Common Name iso, neo, sec...

Is there a reason that tert is used instead of neo?

Re: Oxidation States

Is there a way to figure out what each oxidation state is or does it just have to be memorized for each atom?

Re: identifying oxidation states

I still do not understand how to find oxidation states, could anyone explain how to obtain them?

Why ethanol?

The book says that the new fuels scientists are developing are mostly organic compounds like ethanol. Why are we researching fuels like these if they still contribute to global warming and require significant amounts of energy and water to produce? Why aren't we pursuing clean energies like solar an...

Re: Question on 8.65

I think they were just making the simplest reaction possible to obtain the desired product. That equation is not necessary to solve the problem.

Heat capacity of an ideal gas

According to our textbook, the molar heat capacity of an ideal gas at a constant pressure is greater than the molar heat capacity at a constant volume. I do not fully understand why this is the case and was wondering if someone could help explain it?

Re: Radicals Damaging DNA

Yes, when free radicals interact with DNA, they can cause mutations through oxidation of the DNA. Free radicals are often created as a byproduct when the body metabolizes certain substances such as alcohol, fried food, pesticides, and pollutants. The mutations caused by free radicals often lead to c...

Question 17 A on the Photoelectric Effect Video Module

Question 17 A says; "Light hits a sodium metal surface and the velocity of the ejected electron is 6.61 x 10 5 m/s. The work function for sodium is 150.6 kJ/mol. What is the kinetic energy of the electron?" I know that E(kinetic energy of the electron) = 1/2mv 2 , and E(photon)= work funct...

Re: Classical and Quantum mechanics

I was under the impression that quantum mechanics specifically referred to the energy that can be transferred to or from a particle. Thus it would only deal with electrons and photons rather than large molecules. Is this not the case?
