Answer:
The sign of H is positive, and the products have more potential energy than the reactants.
Explanation:
The options you were given are the following:
- The sign of H is positive, and the products have less potential energy than the reactants.
- The sign of H is positive, and the products have more potential energy than the reactants.
- The sign of H is negative, and the products have less potential energy than the reactants.
- The sign of H is negative, and the products have more potential energy than the reactants.
An endothermic reaction is a chemical reaction that absorbs heat from the surroundings. The absorbed energy provides the activation energy for the reaction to occur.
The sign of H refers to the change in enthalpy. Enthalpy is the thermodynamic property of a system. It is the sum of the internal energy added to the product of the pressure and volume of the system:
If the pressure and volume are constant, the change in enthalpy equals the transferred heat (q). If <em>q</em> is positive, we have an endothermic reaction. The change in enthalpy (the sign of H) in that case always positive, as the change in internal energy is positive (heat is absorbed).
Answer:
1. saturated
2. adapt
3. volatility...mercurial
Explanation:
1. Sodden is a term used to denote that something is completely soaked, oversaturated with water (for example: carpet, clothes, backyard after massive rains, socks etc.) From that, we could infere that "saturated" has the closest meaning to "sodden".
2. From the context of the sentence, we can conclude that businesses need to properly answer to the change of economic circumstances. That basically means that they need to adjust, to adapt to the new situation.
3. Again, we use the context of the sentence to determine the right answer. Basically, the sentence is about a man whose mood changes reflected on the changes of his stock portfolio. So, we need to find the pair of words that denotes changes and inconsistencies, and the only adequate pair is "volatility...mercurial".
The above question requires a personal answer. In that case, I can't write an answer for you, but I'll show you how to do it.
First, you must remember an activity that allowed you to experience a fantasy world, that is, a world outside of reality. You may have had this experience with a video game, a book, and even a movie.
Remember what made this experience satisfying and why the media responsible for this experience are popular and effective.
<h3>Steps to writing your answer:</h3>
- Present the experience you had and which media was responsible for it.
- Show the main characteristics of this media.
- Show how this media can present a mysterious world.
- Show what makes this media attractive and popular so that others have similar experiences.
