Answer:
D
Explanation:
We must study the reaction pictured in the question closely before we begin to attempt to answer the question.
Now, the reaction is a free radical reaction. This implies that only one electron is transferred. The transfer of one electron is shown using a half arrow rather than a full arrow. The both species are radicals (odd electron species) and contribute one electron each.
Hence we must show electron movements in both species using a half arrow.
Answer:
Explanation:
First Question. Answer is: B. They are different.
For examle, balanced chemical reaction of forming water from hydrogen and oxygen:
2H₂ + O₂ → 2H₂O.
During chemical reaction no particles are created or destroyed, the atoms are simply rearranged from the reactants to the products.
Oxygen (element) has boiling point of -183°C and hydrogen has boiling point of -253°C. In this chemical change water (compound) is produced and it has new boiling point, boiling point of water is 100°C.
