Given the balanced equation representing reaction:N2 + energy ==> N + N
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.

Answers

Answer: Option (1) is the correct answer.

Explanation:

In a $N_(2)$ 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 $N_(2) + energy \rightarrow N + N$ shows that N triple bond N is broken down as energy is absorbed by $N_(2)$ molecule.

Hence, we can conclude that in the given reaction bonds are broken, and the reaction is endothermic.

( 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.

What is a harmful effect of electrical resistance?

Answers

While voltage does pose a threat, it's mostly the current that causes damage. There must be voltage available to motivate electrons to flow through a victim. Resistance to current causes (in the case of the victim being human or having flesh) burnt tissues, muscles freezes, and fibrillates hearts.

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.

What kinds of scientific investigations involve making observations?

Answers

1. Coherence Theory (Theory of Coherence)

Based on this theory, a knowledge considered to be true if the knowledge kehoren with the knowledge that exists and has been proven to be true. In the study of mathematics this is usually called the deductive nature.

2. Correspondence Theory (Theory of corespondence)

Based on this theory, a knowledge considered to be true if the knowledge of having a relationship with a reality that is true. This theory is based on the empirical fact that knowledge is true if there are facts that support that is true knowledge. Thus the truth here is based on inductive inference.

3. Pragmatic Theory (Theory of Pragmatism)

According to this theory, knowledge is said to be true if the knowledge is seen practically completely or have properties that true practicality. Followers of this theory argue that knowledge is true if it has keguanaan practical.

A substance that forms a vapor is generally in what physical state at room temperature? solid, gas, liquid or solid, liquid

Answers

Answer:

liquid.

Explanation:

At room temperature, a liquid is, well a liquid, but if you heat it up, it will evaporate into a vapor.

Final answer:

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).

Explanation:

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.
