If you tried forming an ionic bond between sodium and aluminum, would it work? Why? (please help! this is for a friend)

sineoko [7]

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.

A plate and frame filter press with 12 frames is used to filter slurry at constant pressure. Total filtration area is 65 ft2 and

Vladimir [108]

Answer:

$t_2 = 14.4 min$

Explanation:

Given data:

Number of frame is 12+ 8 = 20

Total filtrate is 360 lb

we know

For 1 plate area $= \frac{65}{12} ft^2$

Then for 20 are PLATE $= 20\tmes \frac{65}{12} ft^2 = 108.33 ft^2$

filtrate equation is given as

$t\frac{\mu_s\times(\alpha v) V^2}{A^2(-\Delta P)}$

In the above equation only t and A is variable , all other terms are constant

Therefore we have

$\frac{t_2}{t_1}= \frac{A_1}{A_2} = [\frac{65}{105.33}]^2 = 0.36$

$t_2 = 0.36\times 40 = 14.4 min$

$t_2 = 14.4 min$

Select the chiral center(s) in threonine by clicking on the atom(s). (clicking on an atom will turn it green. if you make a mist

Alborosie

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.
