Urgent needs an answer now Why does it take several redox reactions in a cell to make water from hydrogen and oxygen? Hydrogen and oxygen cannot combine in a single reaction.

Hydrogen and oxygen combine explosively in a single reaction.

Hydrogen and oxygen combine too slowly in a single reaction.

Hydrogen and oxygen combine to form a poisonous byproduct

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

evidence and logical support is essential for a scientist to do in order to maintain credibility. this is because no one can believe without any logic and without any evidence.hence a scientist can maintain credibility by proving himself and by answering logically so experiments prove very beneficial. logical hypothesis give conclusion which is acceptable. therefore, there are two main factors to maintain credibility by a scientist is evidence and logical support.
