I apologize for the confusion. Since I am a text-based AI, I am unable to see or interpret images. Could you please provide a description or text representation of the models so that I can assist you with labeling the blanks correctly?
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, a chemical reaction occurs called combustion. During the combustion reaction, the hydrogen gas (H2) reacts with oxygen gas (O2) to produce water vapor (H2O). The atoms of hydrogen and oxygen are rearranged in the process, forming new chemical bonds to create the new substance, water.
