The half life of uranium-235 is 700,000,000 years. The half life of uranium-238 is 4.463 x 10^11 years longer. What is the half life of uranium-238 the answer should be in decimal form.
To find the half-life of uranium-238, we need to add the additional 4.463 x 10^11 years to the half-life of uranium-235.
The half-life of uranium-235 is 700,000,000 years.
Adding the additional 4.463 x 10^11 years, we get:
700,000,000 + 4.463 x 10^11 = 446,300,000,000 years
Therefore, the half-life of uranium-238 is 446,300,000,000 years.
In decimal form, this is expressed as 4.463 x 10^11 years.
To find the half-life of uranium-238, we need to determine the difference in half-life compared to uranium-235.
Given:
Half-life of uranium-235 (T1/2_235) = 700,000,000 years
Difference in half-life of uranium-238 compared to uranium-235 = 4.463 x 10^11 years
To calculate the half-life of uranium-238 (T1/2_238):
T1/2_238 = T1/2_235 + Difference in half-life
= 700,000,000 years + 4.463 x 10^11 years
= 4.463 x 10^11 years + 700,000,000 years
= 446,300,000,700,000 years
Therefore, the half-life of uranium-238 is approximately 4.463 x 10^14 years in decimal form.
To find the half life of uranium-238, we can calculate it by adding the given difference to the half-life of uranium-235.
Given:
Half-life of uranium-235 = 700,000,000 years
Difference in half-life = 4.463 x 10^11 years (longer than uranium-235)
To find the half-life of uranium-238, add the difference to the half-life of uranium-235:
Half-life of uranium-238 = Half-life of uranium-235 + Difference in half-life
= 700,000,000 years + 4.463 x 10^11 years
Now, let's add the two values:
Half-life of uranium-238 = 700,000,000 years + 4.463 x 10^11 years
= 700,000,000 years + 446,300,000,000 years (converting scientific notation)
Adding the values, we get:
Half-life of uranium-238 = 446,300,700,000 years
Therefore, the half-life of uranium-238 is 446,300,700,000 years.
