When hydrogen gas burns in the presence of oxygen atoms are rearranged and a new substance is formed which of these statements BEST describes what happens
When hydrogen gas burns in the presence of oxygen, the oxygen atoms and hydrogen atoms combine to form water molecules. Therefore, the statement that best describes what happens is: "The hydrogen atoms and oxygen atoms combine to form water molecules."
When hydrogen gas (H2) burns in the presence of oxygen (O2), the atoms are rearranged, and a new substance is formed. The statement that BEST describes what happens is:
The hydrogen atoms combine with the oxygen atoms to form water (H2O).
