Arrange the elements in order of increasing ionization energy: K,Br

In which of the following cases does the reaction go to farthest to completion ?

Mashcka [7]

Answer:

$k=10^{3}$

Explanation:

k stand for equilibrium constants in terms of reaction

The higher the value of an equilibrium constant the faster the equilibrium reaction comes to completion.

Consider the example below:

$R_{1}\ + R_{2}$ ⇄ $P_{1}\ + P_{2}$

where

$The\ equilibrium\ constant\ K = \frac{P_{1}P_{2}}{R_{1}R_{2}}$

For a faster reaction the numerator i.e. the right hand side of the equation have to be higher than the left hand side (the denominator). therefore the higher the numerator, the higher the value of the equilibrium constant and the faster the reaction get to completion thus option c is correct.

Research three different types of fire extinguisher and explain how these can be used to put out different fires, you must relat

Vilka [71]

The fire triangle is composed of
1) heat
2) fuel
3) oxidizing agent (oxygen)

Types of fire extinguishers:
1) Water and Foam - extinguish the fire by taking away the heat element of the fire triangle. Foam agents separate the oxygen element from the other elements.
2) Carbon dioxide - extinguish fire by taking away the oxygen element of the fire triangle and also be removing the heat with a very cold discharge.
3) Dry Chemical - extinguish the fire primarily by interrupting the chemical reaction of the fire triangle.
4) Wet Chemical - extinguishes the fire by removing the heat of the fire triangle and prevents re-ignition by creating a barrier between the oxygen and fuel elements
5) Clean Agent - extinguish the fire by interrupting the chemical reaction of the fire triangle
6) Dry Powder - extinguish the fire by separating thefuel from the oxygen element or by removing the heat element of the fire triangle
7) Water Mist - extinguish the fire by taking away the heatelement of the fire triangle
8) Cartridge Operated Dry Chemical - extinguish the fire primarily by interrupting the chemical reaction of the fire triangle

The compounds below are to be separated by extraction. A student dissolves the compounds in either and then transfers the soluti

gulaghasi [49]

Answer:

1) Separate the aqueous layer from the organic layer using the separation funnel.

2) Treat the aqueous layer to obtain compound A.

3) Distilated the organic layer to obtain compound B.

Explanation:

When NaOH is added to the mixture the acid groups will react to produce a salt and increases the polarity of the compounds due to the net charges generated. (Figure 1).

Therefore, the salt produced by compound A will move to the aqueosus layer. Compound B dont react due to the lack of acid groups. So, this molecule will stay in the organic layer.

When the aqueous layer is separated from the organic layer using the separation funnel we will have a separation. The compound will remain in the aqueous layer and compound b will remain in the organic layer.

Then we aqueous layer can be treated with HCl in order to obtain the initial A molecule, in other words: Undo the ionic form of compound A.

The organic layer can be removed by distillation in order to obtain the pure form of compound B.
