Answer:
Units of energy!
Explanation:
E represents units of energy, m represents units of mass, and c2 is the speed of light squared, or multiplied by itself.
Well the IUPAC naming system is for naming organic compounds in chemistry whereas the taxonomic hierarchical naming system is for classifying and naming species of organisms and finding relationships in terms of physical characteristics. The only way I'd say that they're similar is in the way they actually name the compound/species. E.g, in chemistry, you always have a base name and to that base name you can add a suffix and/or prefix(es). And in biology, you always have the first bit of the me which is the generic name and the second bit of the name which is the specific name. I know this probably wasn't very helpful but this is a very odd question if it's one that would be in an exam because chemistry and biology wouldn't usually be mixed together...
Answer:
One electron is present in 4p energy sublevel.
Explanation:
Gallium element has symbol Ga with atomic number 31.
It is placed in group 13 and fourth period in the modern periodic table.
The electronic configuration of the element, gallium is -
As seen, from the configuration,
<u>One electron is present in 4p energy sublevel.</u>
Exothermic because joules (unit of energy) is on the products side.
