I am in no way confident with my answer but that first equation doesn't really seem to make sense, why would the synthesis of a compound release energy don't reactions such as that require energy?

Well after reading what you have said i do kind of have a visual model that works for me to visualize with although i'm not sure if it is usefull or not. But basically i'm picturing a particle kind of like a strong concentration of magnetic fields (kind of like the atom without the nucleus as everything overlaps) which seems to be good for me to understandi kind of, however this still begs the question of what is creating such fields? but i think that is almost a philosophical question lol

In biology i learnt that osmosis is the phenomena you commonly see in semi-permeable membranes of a cell were water moves from a dilute area (lots of H2O molecules) to a concentrated area (more solute in the water). And then it is pretty much left at that in biology, from a chemistry stand why is this exactly? is it because the ionic charge of the salt that is being diluted attracts more water molecules through the membrane? Or is it more to do with water having more ability to 'move about' in a concentrated solution like other types of diffusion? (which made no sense to me but seemed to be the way my bio teacher was explaining it)

Ok this is likely to be wrong but i got 0.0027 grams of PbCO3, although i have a feeling that may kill her lol

Sorry if i don't word this coherrently because i can't really articulate what i'm thinking in my head. But basically my question is i learnt in chem class that non-polar solutes can't be disolved in polar solvents because the solvent is more attracted to itself then the solute, and that non-polar solutes can only be disolved in non-polar solvents (like dissolves like). What i don't get is why the solute would be diluted at all even in a non-polar solvent, wouldn't it just stay in a more solid state floating in the non-polar solvent having no interaction with it because it has no charge?

Hi, before i ask my question i would firt like to explain that i am not a physics student and that my only source for information of wave-particle duality is from the incredibly unreliable internet. Anyway while reading about the quantum theory of the atom and the idea of electrons acting as both particles and waves i have found myself completely unable to picture this in my head (which is something i really need when i learn something fairly abstract in science). This is because my visualization of a wave is simply a movement of matter, and therefore i can't really see how something could be both a particle and a wave or form of energy. This is really confusing me, as i can't even view a single electron as anything but a particle and therefore feel very limited in furthering my understanding of quantum mechanics. Anyway i figured as students/physicis i was wondering how you picture the wave/particle duality in your heads to see if you could possible help me. Thanks in advance.

Are you sure you can't still use the calculator even if they see that youve cleared all the programmes? they allow those type of calculators at my school as long as they are easily cleared.

Hi i am a new member here and i'm sorry for this paticular amateurish question but its been confusing me in my biology class. My question is why uracil is used to replace thymine in messenger RNA manufacture, while during DNA replication thymine is used? They both are formed from free-floating nucleotides within the nucleus so this has just kind of confused me. Also if this is answered in another post (i have to admit i havn't look too hard) please can i have a link. Thank you in advance.
