<span>A chemical change has occurred because new compounds have been produced.</span>
<span>A,B and D are true, but only A is relevant to the question, so A is the correct answer. I have a book with about 10,000 conversion factors, and often they are confusing, so having lots of standards causes expensive errors. Neil

Answer:
A water molecule
Explanation:
The removal of a phosphate molecule from ATP to form ADP is a hydrolysis reaction. Hydrolysis reactions require water and release energy.
The converse reaction - when a phosphate is added to a molecule of ADP to form ATP - releases water and requires energy.
When air is unstable, circulating motions are strong. When air is stable, circulating motions are weak.
Answer:
Pure covalent bonds exist between two atoms with the same electronegativities. A pure covalent bond has no ionic character at all. Diatomic elements are good examples of pure covalent bonds where the electrons are evenly shared between both nuclei.
