Answer:
C. Chemical reactions may have deteriorated the rubber
Explanation:
A tire ages with time and most of the time this happens due to chemical reactions in the rubber parts. This could happen faster due to heat and sun.
As a tire is deteriorating or aging, a chemical change happens. What happens is that more chemical bonds are going to be produced with time between the molecules. We call this the process of oxidation. This actually bad for the tire, because the rubber would turn out to be stuffs d strong causing the tires thread to separate and also disintegration would occur.
If the hydrate gets too hot it could start splattering and cause a loss of sample.

170 Im pretty sure. It bounces off at the same angle as it is striked
