What are all the alcohols with that molecular formula?

What would be the effect of an increase in temp on the rate constant of a) the forward reaction b) reverse reaction and my second Q is..why is it important to specify the temp when giving a value for Ke? Thanks

did u see my note at the top..I said that all the branched off ones are under C..so none are on the 1st (the reason its on the first is because somehow when I post it they always move to the 1st position)

nm, I figured this out. however, I don't see how to do it the other way around: I have some substances and I need to name them. a) [Cu(Cl4)-2 b) Ag(NH3)+2 c) Cu(NH3)4SO-4 d) Al(H2O)6Cl3 Thanks a lot.

note: the branched of are always under or below C. ok, I have a few more here, which I'll attempt: CH3 | CH3 - CH2 - C - CH - CH3 | | CH3 CH3 so I identify the longest chain of C..which is 5, so once againt its...

thought I'd ask here too..I have 2 quick questions. One is on naming compounds (hydrocarbons) a) CH3 - C = CH - CH2 - CH3 | CH3 (the CH3 should be under the C) what's the key? is number one counting up how many C and H's there are? which element is first? my second question is...

these questions may very well be easy for you..but I am not familiar with calculating voltage and charge. I don't need the answer, just a helpful hint. (a site, or something..I don't mind doing the work but I don't see any useful info about it in my book)

Here is two: Specific heat capacity water - 4.187 kJ/kgK Ammonia 0.037 kJ/(mol Its very easy to find, if you look up the substance like ammonia, just look under thermal properties.

Well, an oxidized substance is one that has lost electrons in the process of getting oxidized and a reduction substance is one that has gained in the process of reduction. I don't understand the half-cell method though. I have looked at examples of balancing an equation using that method but...

1. I have to calculate the voltage of a standard cell with the following half-cell reactions: Ni(s) ---> Ni2+ + 2e- 2e- + Cl2(g) ---> 2Cl- 2. By the electrolysis of water, 11.2L of oxygen at STP was prepared a) What charge was required? b) If a current of 0.5A was used, how long did it...

It aks me to balance some equations, using this method. It says to show both half-cell reactions, and identify them as oxidation or reduction. a) SO3^2 + MnO4- + H+ <----- Mn2+ + SO4^2- + H2O (l) -------> b) Cl2(g) + OH- <----- Cl- + ClO3- + H2O(l)...

Whats the formula for this conjugate bases? how do I get them? a) HSO3tothe(-) b) NH3 c) HCL and how is the lewis acid and lewis base identified? thanks

ok, but the way I am thinking, wouldn't calculation three look the same as one then? I have the 5.5g in Reaction 3, so I would be using the moles of NaOH (0.1375)? Hess's law would be deltaH1 + deltaH2 = deltaH3

Thanks apchemstudent! Here is reaction 1 and 2. I think using Hess's law you can figure out what the third reaction answer should be as well. (a way to check if its right) Can someone who knows show me that. 1) deltaH = m * c * deltaT deltaH = 200g * 1cal/moldegcel * 0.00418kj/cal *...
