The correct answer option d.
Explanation:
When chemical bonds are broken energy is supplied to bond to break it where as when bond is formed energy released during that process.
(ΔH = Positive)
The above reaction represents that two hydrogen atoms are combing together to form a single hydrogen gas molecule.During this process bond id forming between two atoms with release in energy.
Baking something(chemical) and a ice crem melting (phyisical)
The greenhouse effect is a process that occurs when gases in Earth's atmosphere trap the Sun's heat. This process makes Earth much warmer than it would be without an atmosphere. It is one of the things that makes Earth a comfortable place to live.
Answer:
26%
Explanation:
Chlorination is a reaction that substitutes an atom of hydrogen for an atom of chlorine in a hydrocarbon. Pentane has 5 carbons and 12 hydrogens, and the chlorination can happen at the carbons 1,2 or 3. If it happens at carbon 4, the structure will be the same as carbon 2, and if it happens at carbon 5, will be the same as carbon 1.
Then, the percentage of 2-chloropentane and 3-chloropentane is 100 - 22 = 78%. As stated above, 4 hydrogens can be substituted to form 2-chloropentane (two at carbon 2, and two at carbon 4), and only two for 3-chloropentane. So, the percentage of secondary hydrogens to form the structure wanted is:
2/6 = 1/3
Thus, the percentage of it is:
(1/3)*78% = 26%
