Explain why it is important to eat the wet sand before heating the iron wool​

Iron is a metal.

Iron wool is made up of thin strands of

iron loosely bundled together.

Your teacher has attached a piece of

iron wool to a see-saw balance. At the

other end of the see-saw is a piece of

Plasticine.

Iron wool can combust. Your teacher is

going to make the iron wool combust by

heating it.

If there is a change in mass, the see-saw

will either tip to the left or to the right.

Explanation:

huh,eat wet sand b4heating iron wool??

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.

1. they vary with a higher number because boiling is way hotter than melting
