A substance which helps a reaction to take place but that does not take an active part is a?
A substance which helps with chemical reactions, by making them possible at all, or reducing the effort required, is a catalyst.
How do you convert bps to ghz?
You cannot convert between the two since they measure different attributes.
What substances influence other molecules without being changed themselves?
I think what you are looking for is a catalyst. A catalyst lowers the energy or activation for a reaction, allowing it to happen faster. During the reaction nothing actually happens to or changes the catalyst.
What causes molecules to change?
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.
Why would a scientist use a catalyst in an experiment?
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.
What two important attributes of fat in food?

What are all attributes of a parallelogram?
A defining attribute is that it has two pairs of parallel sides. There are lots of other attributes which can be derived from this.
What attributes does a rhombus have?

According to collision theory what best explains how a catalyst increases the reaction rate for a chemical reaction?
A catalyst decreases the threshold energy for a chemical reaction. A catalyst decreases energy required for two particles to react. A catalyst lowers the amount of energy needed to reach the transition state.
What are the two attributes for toy cars?
