Answer: I think it’s compounds only
Explanation:
<span>The natural source of acidity in rain water is all of the above. This is due to presence and abundance of carbon dioxide, nitrogen oxide, and sulfur dioxide in the atmosphere that can dissolve in rain water. Unpolluted rain water is made acidic due to CO2 and H2O in the air that forms carbonic acid.
Nitrogen oxide is mainly present due to the nitrogen fixation caused by lightning, while sulfur dioxide is mainly present due to volcanic eruptions. Other sources such as human activity can also contribute to acid rain. </span>
<u>Answer:</u>
<em>The energy to turn the ice into water:</em>
- The energy that is required to change the state of ice into a liquid is obtained in the form of heat energy from the ambient temperature of the warm room.
- Once this heat energy is absorbed, the individual molecules of ice gain kinetic energy and start vibrating faster.
- Yet, the temperature of the ice remains constant until the ice reaches its melting point because this energy is first utilised to break all the bonds of the lattice structure of the ice.
- After all the bonds are broken and all of the ice has changed into water, if more heat is provided again, then the temperature of the water will increase.
Answer:
the hot fire is depositing heat directly on to the marshmello, heating/cooking it. the hot marshmello then is placed onto chocolate, melting it but idk if that part matters.
