GUYS I NEED FIVE SENTECES IM GIVING BRAINLIEST! Explain how chemical reactions have been used to light and heat homes?

Chemical reactions can heat homes. The reason is sometimes they make a little explosion which can light up the home. And it can linge around for awhile and still light. If chemicals dd not exist Albert would have not invented the lightbulb. That is how chemicals can heat homes.

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.
