What is the maximum number of unpaired electrons that can be accommodated in a 4p subshell?
a. 3
b. 1
c. 7
d. 2

3 unpaired electrons can accommodate in 4 p subshell.

Option A

Explanation:

Each orbits present in an element are further subdivided into different sub-shells. So each subshell can occupy specific number of electrons. The least subshell is the s shell. So the orbital quantum for s is l=0 and p is l =1.

When l=1 , it can occupy maximum 6 electrons in its subshell. In case of unpaired electrons, it will 3 unpaired electrons in the subshell of p. So p subshell will be having 3 unpaired electrons and 6 paired electrons.

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 !
