Answer:
hydrogen and oxygen combine explosively in a single raction
Explanation:
The reason is Molecules of hydrogen react with oxygen violently to break the initial molecular bonds and form new one between the atoms of the two elements. The reaction results into an explosive release of energy and the production of water because the products of the reaction are at a lower energy level
Answer:
Despite a generally high security standard, <u>accidents can still happen.</u> It is technically impossible to build a plant with 100% security. A small probability of failure will always last. The consequences of an <u>accident would be absolutely devastating both for human being as for the nature.</u>
Nuclear power plants as well as nuclear waste could be<u> preferred targets for terrorist attacks. </u>No atomic energy plant in the world could withstand an attack. Such a terrorist act would have <u>catastrophic effects for the whole world.</u>
