The correct answer is C.
Burning is a chemical change. It's a chemical process that includes oxygen.
All the other options are a change of state: form solid to liquid, or from liquid to gas (as in the last one).
Answer:
<em>Most fire extinguishers work by separating the fuel from the oxygen. The oxygen comes from the air. It is the same oxygen we breathe. Since the oxygen has to be in contact with the fuel, if you can coat the fuel with something that keeps the oxygen away, the fire will go </em><em>out.</em><em> </em><em>S</em><em>ome </em><em>ways </em><em>of </em><em>using </em><em>fire </em><em>extinguisher </em><em>are:</em>
- <em> Water extinguishers work mainly by cooling (removing heat), but a dense spray of water droplets also helps to cut off oxygen. </em>
- <em> Dry powder extinguishers soak up heat, melt on the fuel, and cut off oxygen, but they also neutralize the </em><em>fuel</em><em> (cutting it off from the </em><em>fire)</em><em> </em><em>.</em>

Explanation:
because as you pour the blue stuff in it will straight up go to the bottom (and has less blue coloring) Then it will go to the top (lil more blue coloring) then eventually the whole jar will be blue

The number of turns that citric acid cycle will turn when 57.3 g of glucose (C6H1206) is oxidized in the cells is 1.92 × 10²³ turns.
<h3>How to calculate number of turns?</h3>
According to this question, Acetyl CoA turns the citric acid cycle one turn.
First, we find the number of moles of 57.3 grams of glucose by dividing by its molar mass of 180g/mol.
no of moles = 57.3/180 = 0.32moles
Next, we multiply the number of moles by Avogadro's number i.e. 6.02 × 10²³ molecules.
no of turns = 6.02 × 10²³ × 0.32
no of turns = 1.92 × 10²³ turns
Therefore, the number of turns that citric acid cycle will turn when 57.3 g of glucose (C6H1206) is oxidized in the cells is 1.92 × 10²³ turns.
