Answer:
4.47 x 10²² atoms
Explanation:
Given parameters:
Mass of Bismuth = 15.5g
Unknown:
Number of atoms = ?
Solution:
To find the number atoms, first solve for the number of moles in this element first.
Number of moles = 
Number of moles = 
= 0.074mole
So:
1 mole of a substance contains 6.02 x 10²³ atoms
0.074 mole of Bismuth will contain 0.074 x 6.02 x 10²³ atoms
= 4.47 x 10²² atoms
There is one electron in the valence shell of every halogen. Two halogen atoms join together to form a covalent connection (sharing one electron each). Thus, inter-halogen compounds with 1+ or a 1- charge contain an even number of atoms.
An interhalogen compound is a molecule with no atoms from any other group of elements and two or more different halogen atoms (fluorine, chlorine, bromine, iodine, or astatine). The majority of interhalogen chemicals are binary (composed of only two distinct elements).

The reaction is an equilibrium represented by the equation
<span>Ag2CO3(s) + 2 HNO3(aq) <----> 2 AgNO3(aq) + H2O(l) + CO2(g) </span>
From the <span>Le Chatelier's Principle which </span>states that changing a factor such as concentration, temperature, or pressure of a reaction at equilibrium will cause the reaction to shift in the direction that counteracts the effect of that change.
Therefore; the CO2 produced starts escaping and the concentration and pressure of CO2 drops. The system responds by trying to increase the concentration and pressure of CO2 by producing more. This means more and more Ag2CO3 will dissolve due to reaction with the acid, HNO3.
This continues until one of the reactants is exhausted.
