E = mc2
Born on March 14, 1879, Albert Einstein is best known for developing the theory of relativity and the mass-energy equivalence formula E = mc2, often dubbed as 'the world's most famous equation'.
For a star to explode as a Type II supernova, it must be at several times more massive than the sun<span> (estimates run from eight to 15 solar masses). Like </span>the sun<span>, it will eventually run out of hydrogen and then helium fuel at its core. However, it will have enough mass and pressure to fuse carbon.
i had to right an essay on this stuff.</span>
Answer: When a pair of electrons is shared equally between two atoms, the bond formed is called a: pure covalent bond.
I have used the word pure to enphatize that the pair of electrons is shared equally. Some, bonds share the electrons unequally, yet they are covalent but they are polar. When the pair is shared equally the bond is purely covalent.
Also, you must know that covalent bonds may be single (one pair of electrons is shared), double (two pair of electrons are shared) or triple (three pair of electrons are shared).
Answer:
it is the same way it is purified in the state
