Different ketchups have different ingredients. See a few below:
So, short list of chemicals: high fructose corn syrup and acetic acid (vinegar).
the blackish-red stuff that forms on ketchup bottles is a chemical change because things that change colour are mostly chemical reactions i think that's the reason why but i am not sure , but i hope i helped whoever is reading this.
Hardening of ketchup is typically a physical change, as it does not involve a change in the chemical composition of the ketchup molecules. It is usually caused by evaporation of water or cooling of the ketchup, which causes it to solidify.
It is not a chemical change.
These are not chemical reactions but thermonuclear reactions.
Chemical reactions are abbreviated by their chemical equations.
Ketchup
enzymes helps control chemical reactions by the chemical in it called collagen when enzymes enter your body they create a chemical reactions and controls the chemical reactions you get by eating too much acids.
Reactions can be both chemical and physical. Chemical reactions involve breaking and forming chemical bonds leading to the formation of new substances. Physical reactions involve changes in state, shape, or form of a substance without changing its chemical composition.
Not ALL reactions are chemicals. When chemicals reacte with other chemicals it is called as chemical reactions.
There is no chemical name for ketchup. Ketchup is a complex mixture of many different chemical substances.
IT ACCELATATES THE CHEMICAL REACTIONS
chemical reactions are going on in our bodies all of the time
