Hi, in an endothermic reaction:
If the products have gained energy, why do the products get colder?
vice versa with exothermic.
is it that it is stored energy and it is that it's just the surroundings that become colder ?
also. polar molecules:
I dont get the meaning of "cancels out" when describing balanced charges in non-polar molecules due to symmetrical arrangement. Like, it's not like maths. What is actually happening when we say" it cancels out"
Thanks!
