Question 1. Yes, because for a molecule to be formed there must be an effective collision between its constituent atoms. Question 2. Think of it this way, if you powder something it gives more area for the other atoms or molecules to collide with it. But, if you leave something in a brick the atoms or molecules that need to interract with it are only limited to the molecules of the substance on the surface. So thus the more area available for the reaction to take place the faster the reaction.

intermolecular activity is not considered as a chemical reaction but a physical reaction instead since phase changes (solid -> liquid) are not chemical. however im only saying that the dissociation of NaCl APPEARS similar to dissociation when melting a pure peice of salt. one is caused by addition of energy, exciting the salt, the other is caused by dipole-ion forces. (see next post)
@CaitlinB000012 жыл бұрын
I'm just slightly confused by the graph you created to explain activated state and activation energy. On the video, you labeled the y-axis potential energy, but later you referred to heat helping to get up to the activated state. Does the y-axis just represent energy in general, or does heat have a way of changing potential energy that I am not familiar with? (It's late, I hope my question makes sense.) By the way, thanks for all the great videos!!!

i think what causes dissociation is key here and if dipole-ion forces are considered as a physical process instead of chemical, then dissociation of salt in water is a physical process.
@hgfjyrdetryu12 жыл бұрын
i dont think its a chemical reaction since NaCl is an ionic solid meaning each atom is already ionized and independent. the interaction between Na and Cl seems more intermolecular than intramolecular to me because each Na+ ion is not stuck to or permanently designated to a specific Cl- ion, you could melt a pure piece of salt and the Na+ and Cl- ions could be rearranged without going under a chemical reaction (NaCl(s) -> NaCl(l)). (see next post)

well that is a bold assumption because it is different teaching something you know than to answer questions written by others in different manners. Although he would most likely do very well he would probably be prone to making a few errors due to wording or style of the question eventhough he understands the concepts
@chissstardestroyer2 жыл бұрын
Reason if the temperature increases the likelihood increases is simple: temperature at the atomic scale really is the ambient energy of the atoms; so the higher the temperature, the more active they are, and the more likely they are to collide with higher force. Course these things never collide, and the reason for that is at the scale they are at, the electromagnetic force is easily sufficient to stop them from impacting; had they impacted, you'd have a nuclear explosion- and that'd be really bad for the scientists in the lab to put it mildly, as well as the lab in question. Frankly; I doubt very strongly you'd find anything left of the scientists or their experiment if that happened. And that's *if* you can even go near there; due to the radioactive nature of the area post an atomic explosion, as well as finding the epicenter thereof.

@Jordan5066 Just to note that although his equation was balanced, he said "two moles of hydrogen" and "two moles of iodine" which was technically incorrect since H2 is a mole in itself, and the same goes with I2. Correct phrasing: One mole of Hydrogen and one mole of iodine make 2 moles of Hydrogen iodide. H2 is one molecule, and I2 is also a single molecule. It was a long time ago but maybe I was trying to get at that.

These chemicals aren't operating by chance; they are attracted to eachother via electromagnatism- very strongly attracted at that; they are frankly pulled together, due to the electrical charges in the subatomic parts of the atoms.
