Noble gases are the least reactive of all elements. That's because they have eight valence electrons, which fill their outer energy level. This is the most stable arrangement of electrons, so noble gases rarely react with other elements and form compounds.
Molality = moles of solute /mass of solvent in kg = moles of solute x1000/mass of solvent in gm. Moles of solute = molality x mass of solvent /1000 = 0.95x85.4/1000= 0.0811moles.
Answer:
- There are two product produced by the reactants
1. FeI₃
2. Ag₂CO₃
6AgI + Fe₂ (CO₃)₃ ---------> 2FeI₃ + 3Ag₂CO₃
Double Displacement
Explanation:
Incomplete Equation of the reaction is
AgI + Fe₂ (CO₃)₃ --------->
First we have to complete the reaction.
AgI + Fe₂ (CO₃)₃ ---------> FeI₃ + Ag₂CO₃
so from the Reaction
we come to Know about the product
There are two product produced by the reactants
1. FeI₃
Named as Iron iodide also called Iron (III) iodide
2. Ag₂CO₃
Named as Silver carbonate
Balanced equation is based on Law of conservation of mass.
Law of conservation of mass:
"mass can be converted from one form to other but neither can be created nor destroy".
So
To balance a reaction it is important that the number of reactant atoms must equal to atoms of the product.
Atoms of Reactant :
Ag = 1
I = 1
Fe = 2
C = 3
O = 9
Atoms of Product:
Ag = 2
I = 3
Fe = 1
C = 1
O = 3
So,
To balance the equation put numbers as a prefix to formula unit in equation that make atom of the reactant and product become s equal.
its a trail and error process.
Balanced Equation :
6AgI + Fe₂ (CO₃)₃ ---------> 2FeI₃ + 3Ag₂CO₃
Now the numbers of Reactant and product become equal
Atoms of Reactant :
Ag = 6
I = 6
Fe = 2
C = 3
O = 9
Atoms of Product:
Ag = 6
I = 6
Fe = 2
C = 3
O = 9
- This reaction is double displacement. It is also called double replacement reaction.
- it occur when ions of two salts exchange with each other.
- In this reaction Iodide (I¹⁺) ion with exchange carbonate (CO²⁺₃) ion
- and Silver (Ag¹⁺) ion with exchange iron (Fe³⁺) ion
I cause the water to het up, when it do it become a gas.
