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.
The experimental value for Ksp of Ca(OH)2 obtained was much higher than the literature value,
% error = (4.50 x 10^-3 - 4.68 x 10^-6) x 100/4.50 x 10^-3 = 99.90%
The error could have occured due to higher dilution of the solution which enhances the solubility of Ca(OH)2 in the solution.
Between those two years, the number of CO2 emissions almost went up 5 times, just under that number. That is because of the rapid industrialization based fossil fuels, and the number of cars found on the market. This is just another reason why global warming is a man made thing.
Answer:
2C4H10 + 13O2 → 8CO2 + 10H2O

Explanation:
8. <span>The number of protons in the nucleus of an element is called its atomic number.
9. </span><span>If two or more compounds are composed of elements A and B, the ratio of the masses of B combined with 1 g of A is always a ratio of small whole numbers. This is a statement of the law of definite proportions.
