A chemical reaction is a process that leads to the transformation of one set of chemical substances to another. Chemical reactions can be either spontaneous, requiring no input of energy, or non-spontaneous, often coming about only after the input of some type of energy, viz. heat, light or electricity. Classically, chemical reactions encompass changes that strictly involve the motion of electrons.
Congratulations for being the first one to respond to the blog. You mentioned that chemical reactions involve the motion of electrons. Which electrons are involved and how? You didn't describe the evidences for chemical reaction.
A chemical reaction is a change in which a substance is changed into one or more substances. A chemical reaction can either be non spontaneous or spontaneous. Non spontaneous which means it comes after the input of some type of energy, viz. heat, light or electricity. Or Spontaneous which means it doesnt require and input of energy. Chemical reactions involve the rupture or rearrangement of the bonds and it holds atoms together.
A chemical reaction is the process of transformationing one set of chemical substances to another.You know when a chemical change has happened because changes of state may be merely physical.
A chemical reaction is a change in which one or more reactants change into one or more products, but no matter is created nor destroyed. Some evidences of a chemical reaction are heat being created, precipitate being released, and/or color change occuring.
A CHEMINCAL REACTION IS A CHANGE IN WHICH A SUBSTANCE IS CHANGED INTO ONE OR MORE NEW SUBSTANCES. YOU WILL KNOW WHEN THE CHANGE HAS OCCURED BECAUSE THE CHANGES CAN BE PHYSICAL. EVIDENCES ARE SUCH: Chemical changes produce new substances from starting substances, and distinguishing a chemical change from a physical change is based on detecting new substances in the system being observed.
A chemical reaction is basically described as any chemical process in which the substances are changed into different ones especially properties that changes the positions or form phases. These chemical reactions are involved around the rupture or rearrangement of bonds that hold atoms together. I know when a chemical reaction has occured bringing about evidences is that either heat or fog has been created, water released, color change, or bubbling.
A chemical reaction is a change of a substance into a new one that has a different chemical identity. FOr example, the mixture of sodium and chlorine to create sodium chloride or salt. They started off as two different substances but as they were mixed and started to crystillize they made salt. To tell a chemical reaction there are many products to confirm that a chemical reaction. For Example, a change of mass,smell,color,CO2 forming, or excretation of gas. These are all properties of a chemical reaction.
A chemical reaction is a process that leads to the transformation of one set of chemical substances to another. For example you will know when its a chemical reaction because one of the four signs will happen: color change, gas release, new substance forming, and heat gain or loss.
Basically a chemical reaction is a change in which one or more reactants change into one or more products. you pretty much know when a chemical reaction has occurred because the physical damage is very little or slight.

Brie,
ReplyDeleteGreat, you said there will rupture or rearrangement of bonds - do we have a physical evidence for this? What are those evidences?

ReplyDeleteYes, changes of state is merely physical, I agree with you Alexis. However, what are the evidences for chemical reaction/chemical change?

ReplyDeleteAwesome! Is it possible for you to give examples for each evidence that you mentioned?

ReplyDeleteWell Angel, how do you detect the new substances?
