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.

Explanation:
Given reaction:
¹⁰⁸₅₃I → ⁴₂He + ?
An alpha particle decay requires that the mass number decreases by 4 and atomic number decreases by 2.
This reaction is called nuclear fission;
The unknown compound, say Y, will have mass number and atomic number shown below;
¹⁰⁸₅₃I → ⁴₂He + ᵃₙY
Mass number; 108 = 4 + a
a = 104
Atomic number ;
53 = 2 + n
n = 51
Y will be ¹⁰⁴₅₁Y
The atomic number of the new element is 51; so, it is antimony.
¹⁰⁴₅₁Sb
It will sink because water has a density of 1. and 1.1 is greater than 1 which means that the object is denser than the water so it will cause it to sink
Molecular chemical equation:
K₂C₂O₄(aq)+Pb(OH)₂(aq) → 2KOH(aq) + PbC₂O₄<span>(s).
Ionic equation:
2K</span>⁺(aq) + C₂O₄²⁻(aq) + Pb²⁺(aq) + 2OH⁻(aq) → 2K⁺(aq) +2OH⁻(aq)+PbC₂O₄(s)
Net ionic eqation:
C₂O₄²⁻(aq) + Pb²⁺(aq) → PbC₂O₄(s).
s is solid, do not dissolve in water, potassiom hydroxide is trong base and dissolves in water.
The element to which this atom belongs is a p-block main-group element.
What is general electronic configuration?
Electronic configuration or general electron configuration or electronic structure of atoms or ions is the arrangement of orbital energy levels for s, p, d, and f-block elements of the periodic table.
Which group are p-block elements in the periodic table write the general electronic configuration of a p-block element?
Groups 13, 14, 15, 16, and 17 elements comprise the p-block elements. The general configuration of p-block elements is ns2np(1−6).
What is the general configuration of p- block elments?
The general electronic configuration of p-block elements is ns2np1-6 (Except Helium). The number of electrons in the p-block element's penultimate shell is either 2 or 8 or 18.
Therefore, the element belongs to the p-block.
