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>
Ethers can't form hydrogen bonds with water and so have a low solubility
hope that helps
Electrons are released, causing a flow of electrical current,<span>when sunlight strikes a photovoltaic cell.</span>
Carbon has 4 electrons in its outermost shell.it shows tetravalency and catination property hence forms long chain of carbon .
