The half-time of uranium-235 is 700,00,00 years. The half-life of uranium-238 is 4.463 times 10^11 years longer. What is the half-life of uranium-238? The answer should be in decimal form.
The half-life of uranium-238 is 4.463 x 10^11 years longer than the half-life of uranium-235, which is 700,000,000 years.
Therefore, the half-life of uranium-238 can be calculated as:
4.463 x 10^11 + 700,000,000 = 446,300,000,000 years
So, the half-life of uranium-238 is 446.3 billion years.
