Because they speed up reactions that might otherwise take a really long time. Therefore experiments can be condensed into a reasonable time to do in class.
Catalysts speed up chemical reactions.
For example a reaction that may take 15hrs when uncatalysed only takes 10s with a catalyst.
A catalyst speeds up a reaction, by lowering the activation energy of the reaction. This may be one reason with an explanation, However I think they may count as separate reasons.
A catalyst is something that speeds up a chemical reaction.
A catalyst is used to speed up a reaction. It is used in biological reactions as well. Those catalyst are called enzymes.
It increase the rate of the reaction.
The tools that a scientist would use to conduct an experiment would vary greatly on the nature of the experiment.
The reason they would is because it is a lot safer.
the answer is a conclusion
Scientist design experiments to test something.
The scientist's hypothesis of the experiment was that object A would move faster than object B.
The tools that a scientist would use to conduct an experiment would vary greatly on the nature of the experiment.
Most of the metals in the periodic table are used as catalyst for one reaction or the other
dependent variable
Scientist can use the computer for many reasons one reason is to look up information for an experiment.
The reason they would is because it is a lot safer.
the answer is a conclusion
The scientist set an experiment up for mint sweets in cola.
Scientist design experiments to test something.
Chefs have to experiment with different ingredients and recipes just like a scientist would.
The scientist's hypothesis of the experiment was that object A would move faster than object B.
pen, paper, or mouth
Scientist use their data to make charts and GRAPHS to communicate the results of their experiment.
