4 0

Answer:

The Earth has different compositional and mechanical layers. Compositional layers are determined by their components, while mechanical layers are determined by their physical properties. The outermost solid layer of a rocky planet or natural satellite. Chemically distinct from the underlying mantle.

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

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

$t_2 = 0.36\times 40 = 14.4 min$

$t_2 = 14.4 min$

The Ksp of the solution is 1.97 * 10^-9.

The pH is defined as the hydrogen ion concentration of the solution. Now we have the pH of the solution as 10.9.

We know that;

pOH = 14 - pH

pOH = 14 - 10.9

pOH = 3.1

[OH^-] = Antilog [-3.1]

[OH^-] =7.9 * 10^-4 M

Now

Ksp = [M^2+] [2OH^-]^2

Ksp = s * (2s)^2

Ksp = 4s^3

Now s = 7.9 * 10^-4 M

Ksp = 4(7.9 * 10^-4)^3

Ksp = 1.97 * 10^-9

What kinds of intermolecular attractive forces (dipole-dipole, London, hydrogen bonding) are present in the following substances

garik1379 [7]

<span>London forces also known as "induced-dipole-induced-dipole interactions" and are in principle found in every molecule. The interaction occurs from the transient dipoles all molecules have as a result of fluctuations in the instantaneous positions of electrons.
</span><span>Dipole-dipole arises when we are able to set up a polarity in the molecule. So for an example if a highly electro-negative atom is bond to a less electro-negative atom then there will be a polarity in the molecule and we therefore have the dipole-dipole interaction.
</span><span>For the determination of geometry for the specific examples , use the VSEPR (Valence Shell Electron Pair Repulsion) model and by that determine the geometry.</span>

An ion that consists of 7 proton,7 neutrons and 10 electrons has a net charge of ?

natulia [17]

Answer:

C. 3-

Explanation:

Protons have an individual charge of 1+, neutrons have no individual charge, and electrons have an individual charge of 1-.

So the total charge from protons is 7+ and electrons 10-, which gives a net charge of 3-.
