Atomic orbitals represent the wave functions that correspond to the solutions to the schrödinger equation. the orbitals, which do not have specific borders or barriers, represent a volume in space where there is a high probability of finding an electron. the quantum numbers function like an address to give the location of an electron in one of the orbitals. together, the shapes of the orbitals represent the shape of the atom. identify the d orbital.

Explanation:

I'll give you a real answer later need points for test questions sorry

answer; i believe that the correct answer is (a) potassium(k)

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !
