Answer:
D. A brown gas produced
Explanation:
When a chemical reaction occur, there are several changes that takes place such as change in color, odor change, formation of a gas, and formation of a precipitate etcetera.
In the given chemical reaction, two colorless gas (NO and O2) react together and form brown gas (NO2). So, the change of gas from colorless to brown gas is the evidence that shows chemical reaction occurred.
Hence, the correct option is "D. A brown gas produced".
<span>The answer is (1) releases energy. In the cells of the human body, oxygen molecules are used directly in a process of cellular respiration during which energy is released. In cellular respiration, glucose and oxygen yield carbon dioxide and water and energy is released in the form of adenosine triphosphate: C₆H₁₂O₆ (glucose) + O₂ (oxygen) → H₂O (water) + CO₂ (carbon dioxide) + ATP (adenosine triphosphate).</span>
the answer is B) The same number of dots would appear in the diagram for carbon.
The answer is B.
If you put one plant in wet soil, and one plant in dry soil, you can prove or disprove your hypothesis as the plants grow.
weathering takes it away
erosion builds up
Deposition is the geological process in which sediments, soil and rocks are added to a land form or land mass. Wind, ice, water, and gravity transport previously weathered surface material, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of sediment.
the answer is deposition HOPE THIS HELPS
