Answer:
The answer to your question is No
Explanation:
Ionic bonding is a kind of bonding that involves the attraction between oppositely charged ions. That means that one element must have a positive charge and the other a negative charge.
Also, the difference in electronegativity of both elements must be higher than 1.7.
Both Sodium and Aluminum are positively charged then an ionic bond is not possible to be formed.
Difference of electronegativity = 1.61 (Al) - 0.93(Na)
= 0.63
To form an ionic bond the difference of electronegativity must be higher than 1.7.

Explanation:
Given data:
Number of frame is 12+ 8 = 20
Total filtrate is 360 lb
we know
For 1 plate area 
Then for 20 are PLATE 
filtrate equation is given as

In the above equation only t and A is variable , all other terms are constant
Therefore we have
![\frac{t_2}{t_1}= \frac{A_1}{A_2} = [\frac{65}{105.33}]^2 = 0.36](https://tex.z-dn.net/?f=%5Cfrac%7Bt_2%7D%7Bt_1%7D%3D%20%5Cfrac%7BA_1%7D%7BA_2%7D%20%3D%20%5B%5Cfrac%7B65%7D%7B105.33%7D%5D%5E2%20%3D%200.36)


Chiral center is the center where all the attached substituents are different. For example, a carbon is said to be chiral carbon if it is attached to four different substituents.
The structure of threonine is attached here.
The marked carbons are chiral carbons because they have all the 4 different substituents.
