Question

Give an example of how a chemical reaction can be used to do work.

David Collins · Accepted Answer

chemical reactions are very commonly used to provide the energy that can provide the force to move something over a distance. Essentially, the chemical reaction is being used to do work. There were a few examples given in your textbook, one for the automobile engine and another one for a turbine engine. So let&#x27;s review the automobile engine. If we have our fuel gasoline combining with oxygen, it&#x27;s going to produce carbon dioxide and water. Gas is at very high temperatures. Those gasses air going to expand as they expand their going to apply a force upon the head of the piston, moving the piston over a distance and, in turn, doing work. What about a coal power plant? A coal power plant heats up some water. The water turns into steam. The steam applies a force upon a turban to move the turban. Hence the coal. The chemical reaction down here is being used to create work to turn the turban in order to generate electricity.

David Collins · Answer

the chemical reaction could be defined several different ways. I like to think of a chemical reaction. Is the transformation one or more elements or compounds through the process of breaking and forming chemical bonds? Then the new substances that are formed from the formation of new chemical bonds have different chemical and physical properties. Indicators of a chemical reaction can include things such as the production of heat and light gas formation and a color change.

David Collins · Answer

during the chemical reaction. Bonds are broken, new bonds are created and energy is exchanged. The new bonds that created that result in the formation of a new compound.

David Collins · Answer

a chemical reaction is simply a process that converts one arm or substances into one or more different substances, with differing chemical and physical properties typically requiring the breaking and the forming of bonds.

So here we&#x27;re going to be looking at how most chemical reactions occur, so to keep her simple, we can look at this in terms of our collision theory. So if colliding molecules move fast, then the product molecules will form. Whereas if our collision molecules occur to be moving with a letter, amount of energy, then are reactive. Molecules might just bounce off one another due to the lacking of kinetic energy. So in closing collisions a car for the ride range of associative energy values the high energy collisions give products on the low energy collisions tend to not give products in reactions.

Lizabeth Tumminello · Answer

So if you were ever asked about specific chemical transformations that you can observe in everyday life, one specific chemical transformation that you can observe would be rust formation. Another one that you could observe besides rust formation could be, um, something like a fire. Anything burning anything on fire would be an example of chemical combustion. Um, we can also talk about the chemical process off cooking food. We can talk about the chemical process of decomposition when you leave something in your garden and it breaks down. There are different, actually many different chemical processes that cause that decomposition and another chemical process that you or chemical transformation that you can observe on a daily basis would be just that chemical processes that happen in your body to keep you alive. There&#x27;s all sorts of different chemical reactions happening in your body that will keep you alive.
