Naming of Hydrocarbons on the Final

Will we need to know the common names of hydrocarbons on the final or is memorizing the IUPAC naming strategies adequate.

The Functions of Hydrocarbons on the Final

Are we going to need to know the biological functions and smells of hydrocarbons on the final?

Finding the order of a reagent using method of initial rates

When trying to find the order of a reagent in a reaction, I don't understand why you're mathematically allowed to divide one rate formula by another. To me that doesn't seem like that's mathematically allowed. Divided equations by one another isn't something that's allowed in math last time I checke...

Is the differential rate law derived from experimental data?

Is the differential rate law derived from experimental data? Meaning, did chemists just do chemical reactions enough times and manipulated data enough times that they found combinations of terms that seemed meaningful in some way?

OR is there some way to truly derive the differential rate law?

Stoichiometric coefficients and rates

For a chemical reaction, why are the opposites of the chemical equation's stoichiometric coefficients the diving factors used to calculate the rates of the reaction? For example for the equation: 2NO 2 (g) ---> 2NO(g) + O 2 (g) The rate of reaction can be calculated as -1/2*(delta NO 2 )/(delta t) W...

Difference between Joules, Coulombs and Volts

What is the difference between joules, coulombs, and volts? To me they all seem like units of energy, either in the form of work or electric potential, so I don't understand how volts even exist...

Formation of metal ions when metals dissolve

Is it correct that when metals are dissolved in an aqueous solution by an acid the metals always form ions and lose electrons in the process?

Derivation of Boltzwann equation for n moles of gas

I don't understand how kB is changed into nR in the Boltzwann equation for n moles of gas. Can someone explain this please?

Understanding reversible, isothermic expansion

I do not understand how the external pressure can always be equal to the pressure of the gas during a reversible, isothermic reaction and how the dw=-P(ext)(dV) equation is derived. Can someone explain this please?

pH of a solution with a weak acid or a weak base

Because weak acids and bases only partially dissociate into solution and exist in equilibrium with their conjugate what are the pH's of such solutions? Because they exist in equilibrium it seems to me like the solutions would have a neutral pH. Where is my thinking going wrong?

Re: Delocalization of electrons

I have a further question. Specifically which electrons are delocalized when an atom exhibits resonance? For example in benzene there are technically 3 double bonds, but the molecule exhibits resonance, so instead there's an electron cloud full of delocalized electrons rather than 3 double bonds. I'...
