Answer:
The Avogadro's number is 
Explanation:
From the question we are told that
The edge length is 
The density of the metal is 
The molar mass of Ba is 
Generally the volume of a unit cell is
substituting value
![V = [5.02 *10^{-10}]^3](https://tex.z-dn.net/?f=V%20%3D%20%20%5B5.02%20%2A10%5E%7B-10%7D%5D%5E3)
From the question we are told that 68% of the unit cell is occupied by Ba atoms and that the structure is a metal which implies that the crystalline structure will be (BCC),
The volume of barium atom is
substituting value
The Molar mass of barium is mathematically represented as
Where 
is the Avogadro's number
So
substituting value
A(n) strong acid or base will dissociate completely in water, whereas a(n) weak acid or base dissociates very little in water.
Strong acids are defined as any acid that completely dissociates into ions. It is a weak acid if dissociation is less than 100%.
Strong bases are defined as any acid that completely dissociates into ions. It is a weak base if dissociation is less than 100%.
Not every acid or base ionizes or dissociates to the same degree. This supports the claim that not all acids and bases have the same ability to produce H+ and OH- ions in solution.
The adjectives "strong" and "weak" describe how strong an acid or base is. The ability of acidic and basic solutions to conduct electricity is referred to as strong and weak.
Strong electrical conductivity indicates that an acid or base is a strong acid or base. A weak acid or base is one that conducts electricity only slightly.

Answer:
14mph
Explanation:
270 minutes = 4 hr and 1/2hr
63 miles = 63/4.5 = 14 miles per hour
Making the speed 14mph
Equation = h = 4.5
(4h x 4h ) + (1 x 311/100) = 60
= 4h x 4h +( 1 x 311/100) =60
= 16h^2 + (1 x 311/100) =60
= 256h + (1 x 311/100) =60
= 256h + 14 = 60
= 270h = 60
= h = 4.5
Answer:
Explanation:
To fill in the gaps with the appropriate words, we need to rewrite the whole text in the question while adding the right answers to it.
