Answer:
Explanation:
Hello,
Here, by using the Dalton's law, we can quantify the total pressure of a gaseous mixture by knowing the partial pressure of each gas, in case, hydrogen, helium and argon:
In such a way, since we actually know the partial pressure of helium and argon, and the total pressure, we can compute the partial pressure of hydrogen as shown below:
Best regards.

The atomic and mass numbers of the daughter isotope, which emits a beta particle 91, 232
Isotopes belong to the same elemental family but have different ratios of neutrons to protons, making them different substances. On the Periodic Table, each element's atomic number is based on how many protons are in its nucleus.
Isotopes are two or more different atom types that share the same atomic number and place in the periodic table but have different quantities of neutrons in their nuclei, resulting in various nucleon numbers. Despite having various atomic weights and physical characteristics, they exhibit roughly the same chemical activity. Isotopes are variations in the mass number, "A," of an element's atoms that share the same number of protons (atomic number, "Z") but a different number of neutrons.

In chemistry, neutralization is a chemical reaction in which an acid and a base react quantitatively with each other, and where the final Ph of the solution is neutral (7).
In a reaction in water, neutralization results in there being no excess of hydrogen or hydroxide ions present in the solution.
