<span>The answer is "his conviction and execution should be upheld". Frank Palko was first charged with murder and claimed that Connecticut violated the Double Jeopardy Clause of the Fifth Amendment. The fifth amendment states that "there must be no person to be put twice in jeopardy of life and limb" so this was the violation the court made after they charge him with murder for the second time. That's why when the second trial was made,he was sentenced to by the Supreme court which decided that he should be executed and convicted because of the evidences found.</span>
<h3>Answer:</h3>
18.75 grams
<h3>Explanation:</h3>
- Half-life refers to the time taken by a radioactive material to decay by half of the original mass.
- In this case, the half-life of element X is 10 years, which means it takes 10 years for a given mass of the element to decay by half of its original mass.
- To calculate the amount that remained after decay we use;
Remaining mass = Original mass × (1/2)^n, where n is the number of half-lives
Number of half-lives = Time for the decay ÷ Half-life
= 40 years ÷ 10 years
= 4
Therefore;
Remaining mass = 300 g × (1/2)⁴
= 300 g × 1/16
= 18.75 g
Hence, a mass of 300 g of an element X decays to 18.75 g after 40 years.
