Two ways that can be used to identify which layer is organic and which layer is the aqueous layer in a liquid-liquid extraction are:

There are many methods that can be used to distinguish two layers from each other using contrast between the two substances in certain properties. One of the common methods that can be used to distinguish aqueous layer from an organic layer is adding water to mixture and observing which layer increases in size. The layer that increases in the size is the aqueous layer, as water is immiscible with organic layer. Thus, water can only increase aqueous layer. Another way is, for a start, the ethereal layer, even laden with organic solute, should be less dense than aqueous layer, and thus should be floating on top. Sometimes you can even tell by rubbing solvent with your fingers.

<h3>What is extraction?</h3>

Extraction is a process used in organic chemistry for isolating a certain substance or a compound from its source material. Since the source material is composed of the various molecules and compounds but only a specific compound is needed, the desired compound has to be separated from the mixture.

A liquid-liquid extraction method is a method used to extract substance using the two immiscible of different natures. Since two liquids are immiscible, they liquids form the two layers when added to the same vessel. This is typically done using the water and an organic solvent that is insoluble in water. When two are mixed, they form an aqueous layer and an organic layer.

If the Earth is round... why is the land flat?
stiv31 [10]

Answer:

See explanation

Explanation:

The land around us appears flat because the Earth is just so unimaginably large, and the curvature is extremely small from our point of view. In reality, the land is slightly bendy, which is why certain structures (like very long bridges) need to be constructed with the curvature in mind, with different ends at slightly different elevations. Hope this helps!

Nitrosyl bromide decomposes according to the chemical equation below. 2NOBr(g) 2NO(g) + Br2(g) 1.00 atm of NOBr is sealed in a f
Andrew [12]

Given :

2NOBr(g) - -> 2NO(g) + Br2(g)

Initial pressure of NOBr , 1 atm .

At equilibrium, the partial pressure of NOBr is 0.82 atm.

To Find :

The equilibrium constant for the reaction .

Solution :

             2NOBr(g) - -> 2NO(g) + Br2(g)

t=0 s           1 atm                 0             0

t=t_{eqb}       1( 1-2x)               2x           x

So ,

1-2x=0.82\\\\x=0.09

At equilibrium :

K_{eq}=\dfrac{[NO]^2[br_2]}{[NOBr]^2}\\\\K_{eq}=\dfrac{0.18^2\times 0.9}{0.82^2}\\\\K_{eq}=0.043\ atm

Hence , this is the required solution .

Protons:

- Have a mass

- Positively charged

- Found inside the nucleus of an atom

Electrons:

- Have a mass. (9.10938188×10−31 kilograms), though this can sometimes be considered negligible due to how small that actually is. Barely factored into atomic mass

- Negatively charged

- Found outside the nucleus in the electron shell

Neutrons:

- Have a mass

- Neutral (no charge)

- Found inside the nucleus of an atom

Atom A:

- 1 proton

- 0 Neutrons

- 1 electron

- Atomic mass of 1

- Atomic number of 1

Atom B:

- 8 Protons

- 10 Neutrons

- 8 electrons

- Atomic mass of 18

- Atomic number of 8

Atomic mass includes the number of protons and neutrons in the nucleus. Atomic number is the number of protons, as this is what defines what type of element the atom is.

A solution of starch at room temperature does not readily decompose to form a solution of simple sugars because
Basile [38]

Explanation:

The starch requires a temperature higher than the room temperature (arround 60 °C) to decompose to form simple sugars. This is because the energy required to break the chemical bonds. Also, it may need the action of some specific enzymes (alpha and beta amilase) to break those bonds.
