Atomic physics is the field of physics that <span>studies atoms.
</span>In 1913, Niels Bohr made a theory for the hydrogen atom based on quantum theory which states<span> that energy can only be transferred in certain quantities. Electrons move around the nucleus but only in fixed orbits. When an atom jumps from one orbit to another with lower energy level, a light quantum is emitted as a result.</span>
<span>C7H16 + 11 O2 = 7 CO2 + 8 H2O
If you write it like this then it is balanced.</span>

Answer: Basilosaurus is a prehistoric whale which lived approximately 40 million to 34 million years ago during the Late Eocene Period.
Explanation:
Answer is:
4-ethyl-1-heptene.Structure of this alkene is in Word document attached.
<span>First find main chain with longest number of carbon atoms, that is chain with seven carbon atoms and it start on the right and going up the three-carbon attachment.
Main chain has double bond between first and second carbon (</span><span>the lowest number)</span><span>, so it is 1-heptene (alkene).
</span>Substituent is on fourth carbon atom, it is alkyl group with two carbon atoms (ethyl).
