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
The debate is a complex one but how I look at it, I believe it is murder. Murder seems to be too strong of a word but it is a termination of potential life. I just do not believe that we should stop a natural process from happening. I don't care how far it is into the process, that's beside the...
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
