Neptunium-237 was the first isotope of a transuranium element to be discovered. the decay constant is /s. what is the half-life
1 answer:
The half-life in years of Neptunium-237 which was the first isotope is 2.1 years.
Neptunium is most stable and Neptunium-237 is undergoes alpha decay, it means Neptunium-237 is decays by the emission of alpha particles . Seven alpha particles is emitted during decay of Neptunium-237. Neptunium-237 is radioactive actinide elements and first transuranium element.
The transuranium synthesis process involves creating a transuranium element through the transmutation process . The transmutation process is the process of creating heavy elements from light elements. Hence the process is the transmutation of light elements. There are two types: artificial and natural transmutation.

Answer:
Solution Y is more acidic
Explanation:
The pH value is an indicator of the concentration of hydrogen ions (H⁺) in an aqueous solution, and it is defined as:
pH= -log [H⁺]
⇒
Where [H⁺] is the concentration of H⁺. A solution with a higher concentration of H⁺ is more acidic, and a solution with a lower concentration of H⁺ is less acidic or basic.
As result, <em>the lower the pH, the more the concentration of hydrogen ions ([H⁺]), and the aqueous solution is more acidic</em>.
Solution Y has a lower pH value (7.5) than solution X (9.4). So, solution Y is more acidic.
