The half-life of uranium-235 is 700,000,000 years. The half-life of uranium-238 is 4.463×10^11 years longer. What is the half-life of uranium-238? The answer should be in decimal form.

Answer 1

To find the half-life of uranium-238, we need to add the additional time to the half-life of uranium-235.

Given:
Half-life of uranium-235 (t₁/₂₁) = 700,000,000 years
Additional time for uranium-238 (tₐ) = 4.463×10^11 years

Half-life of uranium-238 (t₁/₂₂) = t₁/₂₁ + tₐ

Substituting the given values:
t₁/₂₂ = 700,000,000 years + 4.463×10^11 years

Calculating the sum:
t₁/₂₂ = 4.463×10^11 + 700,000,000 years
t₁/₂₂ ≈ 446,300,000,000 years

The half-life of uranium-238 is approximately 446,300,000,000 years.

Answer 3

Apologies for the incorrect previous response. You are right.

The correct half-life of uranium-238, when considering the additional time of 4.463×10^11 years, is 4.4637×10^11 years in decimal form.
