Answer:
1. absorbs and re-emits infrared radiation
2.three or more atoms in a molecule
Explanation:
research, lots of research.
They use experimental investigations where they manipulate variables
They travel linearly.
They have a negative electric charge.
They have particle property.
Magnets can deflect them.
Charge/mass ratio of the rays is constant.
They travel from the cathode to the anode.
Their properties are independent from the electrodes and gas present in the cathode ray tube.
I believe the correct answer from the choices listed above is option A. It is a catalyst that <span> increases the rate of a chemical reaction. It provides another pathway for the reaction in order for it to hasten the speed of the reaction. Hope this answers the question. </span>
