AI Thread Summary
The discussion focuses on verifying net ionic equations for reactions involving sulfur trioxide, carbon dioxide, strontium chloride, sodium sulfate, hydrochloric acid, and sodium hydroxide. The first equation is incorrect as it mistakenly includes water as a reactant; the correct reaction involves sulfur trioxide and carbon dioxide without a net ionic equation due to no soluble species. The second equation for strontium chloride and sodium sulfate is confirmed correct, with the net ionic equation accurately representing the formation of solid strontium sulfate. The third equation involving hydrochloric acid and sodium hydroxide is generally acceptable, though some participants express uncertainty due to a lack of recent practice in the subject. Overall, the discussion emphasizes the need for careful attention to reactants and the conditions of each reaction.

I need to include net ionic eq, phase symbols, etc.
1. Sulfur trioxide is heated with carbon dioxide.
2. A solution of strontium chloride is mixed with a solution of sodium sulfate.
3. Hydrochloric acid is added to sodium hydroxide

My work:
1. SO3(g)+H2O(l)---->H2SO4(aq)
2. Sr^{2+}(aq)+SO4^{2-}------> SrSO4(s)
3. HCl(aq)+NaOH(aq)------->H2O(l)+NaCl(aq)
H^{+}(aq)+OH^{-}(aq)----->H2O(l)

Are these right? Any corrections?

carbon dioxide?
 
the first one is def. wrong. where did u get H20 as a reactant? the original problem states "Sulfur trioxide is heated with carbon dioxide." Re-work the first one, and for a hint, there will be no net ionic reaction for this one b/c nothing is in solution.

the second one is right. the overall is SrCl2 + Na2SO4 ---> SrSO4 + 2 NaCl, and the net ionic reation you have looks good.

the third on looks ok, but I am not too sure. that chemistry is now buried under a semester of organic chem, so forgive me if I am rusty

Thread 'Confusion regarding a chemical kinetics problem'

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
