A 100. mL reactor vessel is charged with 250. mg of P 4 and 4.21 atm of C l 2 at 298 K. The reaction goes to completion. How man
1 answer:
There are 0.0172 moles of chlorine gas initially in the vessel.
Suppose we take a look and consider the reaction between P4 and Cl2, the balanced chemical equation between them can be expressed as:
Given that:
- mass of P₄ = 250 mg = 0.25g
- pressure of Cl₂ = 4.21 atm
- volume of the reactor = 100 mL = 0.1 L
- temperature = 298 K
Using the Ideal gas equation, the number of moles of chlorine gas that were initially present in the vessel is:
PV = nRT
Making (n) the subject of the formula:
n = 0.0172 moles
Therefore, we can conclude that there are 0.0172 moles of chlorine gas initially in the vessel.

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.
