Answer:
See explanation
Explanation:
Light is a form of energy. Both ultraviolet light and xrays are part of the electromagnetic spectrum.
As was said in the question, ultraviolet rays is absorbed by the rubber. We must know that prolonged exposure of this piece of rubber to incident ultraviolet light causes the vaporization of volatile materials in the rubber.
When volatile materials in the rubber vaporize, the rubber can become solid. Thus, ultraviolet light can cause rubber to become solid.
However, not all types of light can do this hence it does matter the type of light that falls on the rubber material.

This is because all steps from A-D are important to obtain an accurate result
Answer:
See below
Explanation:
<u>Specific Heat of water</u> = 4.186 J/(g-C)
J/(g-C) multiplied by g and C results in J
4.186 * 540 * (95-32) = <u>142 407 .72 J</u>
the balanced chemical equation representing the reaction between represent sodium metal (Na) and chlorine gas (cl2) is as below
2 Na + Cl2→ 2 NaCl
2 moles of sodium metal ( Na) reacted with 1 mole of gas chlorine gas (cl2) and 2 moles of sodium chloride (NaCl)
