Which statement describes this reaction?
( I) Bonds are broken, and the reaction is endothermic.
(2) Bonds are broken , and the reaction is exothermic.
(3) Bonds are formed, and the reaction is endothermic.
(4) Bonds are formed, and the reaction is exothermic.
Answer: Option (1) is the correct answer.
Explanation:
In a molecule, the nitrogen atoms are bonded together by triple bond.
Therefore, in order to break this triple bond high heat or energy has to be provided.
Thus, the reaction shows that N triple bond N is broken down as energy is absorbed by
molecule.
Hence, we can conclude that in the given reaction bonds are broken, and the reaction is endothermic.

Answer:
Resistance resist the flow of current. This means that if 5V go through a resistance, it'll be reduce down to something below or equal to 5V.
If it gets reduce below 5V, lets say it goes down to 3V, the extra 2V must go somewhere. That 2V energy is converted to heat and dissipated through the resistor.
If there's a big current then the energy dissipated will be huge. And more negery = more heat which can cause fire and burn you.
Answer:
the hypothesis is the anawer.
Answer:
liquid.
Explanation:
At room temperature, a liquid is, well a liquid, but if you heat it up, it will evaporate into a vapor.
Usually, substances that form a vapor at room temperature are in the liquid or solid state. This happens because of evaporation (in liquids) and sublimation (in solids).
A substance that forms a vapor is typically in a liquid or solid state at room temperature. This is due to the process called Evaporation for liquids and Sublimation for solids. Evaporation is when a substance changes from a liquid to a gas at temperatures below its boiling point. Sublimation, on the other hand, is when a solid changes directly to gas without passing through a liquid stage. These processes can happen at room temperature, depending on the substance.
