that is true
Yes, it's true.
Yes. it is true.
It is true that a catalyst is used in chemical reactions to help speed up the reaction by reducing activation energy.
it isnt true
no it isnt
When reactants are binding to the surface of the catalyst, it is important that the catalyst is strong enough to allow a reaction to take place, however having a strong catalyst could mean that the products could permenantly bind to the catalyst, which is a problem. So if the catalyst is too strong, the catalyst isnt very sucessful, and if it is too weak, it also isn't sucesful.
No, it is not true that a catalyst raises the activation energy of a reaction. In fact, a catalyst lowers the activation energy, allowing the reaction to occur more easily and at a faster rate. By providing an alternative pathway for the reaction, catalysts facilitate the formation of products without being consumed in the process.
I think this refers to catalysts as these are considered not to be changed by a reaction-- sometimes this true when molecules react on the surface of a catalyst bu sometimes the catalyst does get involved in the chemical reaction- but is regenerated.
no it isnt true . crows prepare their own nests but cuckoos steal others nests
you cant actually that isnt true i know someone who has sensei on their buddy list
It is true that human preception of animals isnt the same as the animals'
