Chemical reactions section lists the wrong number of reactions
I am not a science expert but the section for types has a header that says "four basic types" then lists synthesis, decomposition, single-replacement, double-replacement, and combustionm which are five types. Not sure if the number of types of reactions is wrong or the list of types is wrong but this is confusing. AaronY (talk) 11:15, 24 March 2021 (UTC)

Please add an another characteristic of chemical reaction "Change on colour" 114.134.20.99 (talk) 16:35, 21 August 2021 (UTC)
Not done: it's not clear what changes you want to be made. Please mention the specific changes in a "change X to Y" format and provide a reliable source if appropriate. ScottishFinnishRadish (talk) 17:40, 21 August 2021 (UTC)

Forward and backward reactions
@Materialscientist: In this revision, you reverted my addition of forward reactions and backward reactions, which are important types of reactions.
I just want to make sure that it would be okay when I add this content again by citing reliable sources, which I will do when time suffices. — CrafterNova [ TALK ] [ CONT ] 03:47, 10 April 2023 (UTC)
- I could not find a chemical equation for "charging a normal DC battery (consisting of electrolytic cells) from an external electrical power source". Can anyone help? — CrafterNova [ TALK ] [ CONT ] 18:07, 11 April 2023 (UTC)
Proposed merge of Chemical change into Chemical reaction
The following discussion is closed. Please do not modify it. Subsequent comments should be made on the appropriate discussion page. No further edits should be made to this discussion.
A chemical reaction and a chemical change is the same thing. Since chemical change has very small amount of content, merging it with chemical reaction won't put undue weight (WP:UNDUE) or overload the target article, but any redundancy in text should be reduced as much as possible per WP: REDUNDANCY. — CrafterNova [ TALK ] [ CONT ] 07:27, 12 May 2023 (UTC)
- I don't agree with it,they are same with a little difference.chemical changes means change in chemical structure of a substance while chemical reaction is a process by which this change happens.So merging a change with a process with ideology that they are same isn't a wise decision AryanpateI (talk) 05:37, 29 July 2023 (UTC)
- I do not agree with the above. Chemical change is widely used to be more than just change in chemical structure of a substance. It used to be that but it is also frequently used to mean the same as chemical reaction, so merge. --Bduke (talk) 06:51, 29 July 2023 (UTC)
- A chemical reaction is an effect: something that happens. A chemical change is an affect: the RESULT of an effect. They are distinctly different, albeit related. Regardless, they're different enough that separate pages can be warranted. 2600:6C40:5F00:B1:DF2:5317:6E75:5D1 (talk) 05:05, 15 August 2023 (UTC)

- Support merge, on the grounds of short text and context. That is, Chemical change is short, and better discussed in the context of the better-developed chemical reaction page. It's of course accepted that these are different thing (transition and final state), but they are so closely related that they are best described in one place. There is already overlap - for example, the Chemical change#Types mostly discussed reactions. Klbrain (talk) 14:54, 18 November 2023 (UTC)
- Support. Yes, they're not the same, but it's similar and short enough for separate articles to be redundant. QueenofHearts 21:28, 20 January 2024 (UTC)

Chemical reactions and bonds
How can i differentiate chemical bond and reactions
- grade 8
confused 🙏 make it easy 41.13.74.87 (talk) 19:01, 18 November 2024 (UTC)
- A chemical bond helps to hold ONE molecule together. For example, the bond in H-Cl is the line between the 2 atoms.
