Question

In your own words, dei ne exothermic and endothermic chemical changes.

David Collins · Accepted Answer

question number one asks you to define endo thermic and eggs. A thermic chemical changes. Although the power in this question is going to be for you to think about these definitions and write it in your own words. Here is an example. An extra thermic process or an extra thermic chemical change is going to be something that occurs. We&#x27;re typically focusing on a chemical reaction that releases heat energy into the environment at constant pressure, while in the case of an endo thermic change or chemical process or process chemical change. If we&#x27;re focusing on a chemical reaction, it&#x27;s a chemical reaction that absorbs heat energy from the environment, so the environment actually cools down at constant pressure.

explain how energy changes from one form to another in an ex Olympic reaction and in then, and the dimmer reaction. You know that in a excellent Rick reaction that are chemical potential, energy from a warm object is transferred to heat, which is, and they really and in then Endo direct reaction. We have energy which is transformed to chemical energy.

Carlene Jimenez · Answer

So this question wants us to compare exo, thermic and endo. Thermic reactions, son Exo. Thermic reaction is one that releases heat and then Endo. Thermic reaction is one which absorbs heat. Another useful way of thinking about them is thinking of an exo, thermic reaction as one where heat is a product and an endo thermic reaction is one where heat is a reactant.

Rachel Vallejo · Answer

all rights for this question, whereas to discuss Exit Eric processes and India thermic processes and give in to examples of each. So to start, what&#x27;s an extra there it process next. A thermic process is one where energy is a product. A right reaction generates energy. In this case, the products have less energy than the reactant, so when you subtract the amount of energy of the reactions from the products, you&#x27;ll get a negative number. So what&#x27;s an example of an extra thermic process? Well burning a match and melting and ice cube. So with burning a match, the excess energy created by this reaction is obvious. On the form of heat and light melting ice cube, you can see the excess energy and that the atoms of the Ice Cube, which were closely packed together, gained energy and are now able to move around more as water rights over an endemic process and then does the right process is a process that where energy is a reacted energy is required for the reaction to take place. In this case, the energy of products is greater than the energy of the reactions, and when you subtract the energy of the reactions from the products, you get a positive number. So what&#x27;s an example of Indo thermic reaction? Well, freezing water into an ice cube and also condensation water vapour turning into liquid water. Now, in both of these cases, the molecules had more energy and then slowly lose energy. So for condensation, the water vapour molecules, they were had a lot of energy. And then when you reduced that energy, yeah, they got closer together and were able to form water. When you freeze water, the water, the bonds, the M, the molecules in the water were able to move pretty freely. They were still close enough together that they were actually they formed water, but they weren&#x27;t frozen. And, of course, when you freeze that water there basically stuck where they are, they don&#x27;t have as much movement. They&#x27;ve lost energy and actually into three processes air associated with cooling down and what you can tell when things become frozen, they get colder. Of course,

Ronald Prasad · Answer

the law, a conservation of energy states energy can neither be created or destroyed. Energy can be transferred from one object to another, and it can assume different forms in and energy exchange. Energy is transferred between the&#x27;s system and these rentals. The system loses energy. These surroundings gain energy and thanks person in chemical on physical changes matter often exchanges energy with its surroundings. In these exchanges, total energy is always conserved.

Why does an endothermic reaction that takes place…

Problem 1 Easy Difficulty

In your own words, dei ne exothermic and endothermic chemical changes.

Answer

Exothermic chemical changes refer to reactions that give off (evolve) heat to the surroundings. In an
endothermic chemical change, heat is taken in (absorbed) from the surroundings.
