Experimenting with Acids & Bases: DeltaH, Dissociation & Bond Strength

AI Thread Summary
The experiment compared the heat of energy released during reactions of a strong acid (HCl) with a strong base (NaOH) and a weak acid (ethanoic) with the same strong base. The results indicated that the reaction involving the strong acid produced a greater heat of energy than the reaction with the weak acid. This difference is attributed to the complete dissociation of strong acids compared to the partial dissociation of weak acids. The discussion also highlights the importance of bond strengths and dissociation in determining the energy changes in these reactions. Clarification on specific numerical values from the experiments was requested for further analysis.

I did an experiment with

a) strong acid (HCl) and strong base (NaOH)

b) weak acid (ethanoic) and strong base (NaOH)

so, I am looking at the heat of energy for both the reactions, and so i found that reaction a had a greater heat of energy was that of the reaction b) weak acid and strong base, (using the formula deltaH= mcT)

why would this be, in terms of dissociation or bond strenghths? i know that acids completely dissociate, but not too sure about the difference between weak acid and strong acid... help please!

Weak acids are not completely dissociated.

Are you neutralizing here? What are the values that you got?

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...
