Different ketchups have different ingredients. See a few below:
So, short list of chemicals: high fructose corn syrup and acetic acid (vinegar).
Ketchup contains many thousands of chemicals. One would be acetic acid, another would be sucrose and another would be sodium chloride.
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.
These are not chemical reactions but thermonuclear reactions.
Chemical reactions are abbreviated by their chemical equations.
It is not a chemical change.
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.
4 useful chemical reactions are: fermentation, smelting combustion and electrolysis
Not ALL reactions are chemicals. When chemicals reacte with other chemicals it is called as chemical reactions.
Chemical reactions are chemical processes.
IT ACCELATATES THE CHEMICAL REACTIONS
enzymes involve in bio chemical reactions.
A catalyst helps chemical reactions occur.
chemical reactions are going on in our bodies all of the time
