Hello, Why does the water inside a bottle condense within a few minutes/hours after drinking from it by mouth? I would prefer a scientific chemical explanation with you; I can imagine that it has something to do with saliva and bacteria.
Does anyone know a good simulator to demonstrate the autoprotolysis of water? or general chemical reactions
Why is the formula for copper sulfide CuS and not Cu₂S? Copper has one electron in its outermost shell. Sulfur has six, so it needs two electrons of copper to fill the shell.
Good evening, Can you explain to me what happens during reduction and oxidation using an example? For example, when rust rusts. Do you know of similar examples? Lg

Eq = m * c* delta T
use c of water.
you can do if you shy the effort to search in the net for the exact values.
The error becomes smaller when starting from 80 ml of water and not from 81.5 g.
