This question seems to refer to a specific set of images or models that are not provided in the question. Without the visual representations to refer to, it is not possible to accurately label the boxes. Please provide the necessary visuals or further information in order to assist with this question.
Consider the reaction represented by the space-fill models shown. Drag the correct label to each box.
Blank 1 represents the substance(s) on the left
Blank 2 represents the arrow in the middle
Blank 3 represents the substance(s) on the right
Blank 1 represents the substance(s) on the left
Blank 2 represents the arrow in the middle
Blank 3 represents the substance(s) on the right
Since the space-fill models are not provided, we cannot directly observe the substances or the reaction. Consequently, it is not possible to assign labels to Blank 1, Blank 2, and Blank 3 without any information or visuals. Please provide additional details or images in order to answer the question accurately.
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 (H₂) burns in the presence of oxygen (O₂), a chemical reaction called combustion occurs. During combustion, the hydrogen and oxygen atoms rearrange to form water (H₂O). This reaction can be summarized by the chemical equation:
2H₂ + O₂ → 2H₂O
In this reaction, the hydrogen and oxygen molecules combine to form water molecules. The arrangement of atoms is altered, resulting in the formation of a new substance (water).
2H₂ + O₂ → 2H₂O
