solution is attached below in figure .
and table is in word document
Conductivity is the ability of a substance to allow charge or electricity to pass through it. Metals have a lot of free electrons and are considered as good conductors while non-metals do not conduct electricity
1) In the given examples:
Al is a metal, Na is an alkali metal while P is a non-metal
The decreasing order of conductivity would be:
Al > Na > P
2)
Both Al and Ga are metals while B is metalloid.
Among Al and Ga, Al is a solid at room temperature and a better conductor of electricity. hence the decreasing order would be:
Al > Ga > B
Answer:
2 KF ₍s₎ → F₂ ₍g₎ + 2 K ₍s₎
Explanation:
Chemical Formula of Potassium Fluoride = KF
Chemical Formula of Fluorine Gas = F₂
Chemical Formula of Solid Potassium = K
Step 1: Write the unbalance chemical equation,
KF → F₂ + K
Step 2: Balance Fluorine Atoms;
As there is one fluorine atom on left hand side and two fluorine atoms on right hand site therefore, to balance them multiply KF on left hand side by 2 i.e.
2 KF → F₂ + K
Step 3: Balance Potassium Atoms;
As there are two potassium atoms on left hand side and one potassium atom on right hand site therefore, to balance them multiply K on right hand side by 2 i.e.
2 KF → F₂ + 2 K
Step 4: Assign Physical states as,
2 KF ₍s₎ → F₂ ₍g₎ + 2 K ₍s₎
