Answer:
Explanation:
Part a
Normal Phase Chromatography
In the normal phase chromatography, the eluting power is highest for the solvent which has the highest polarity.
So from the given solvents as Methanol, Dichloromethane and Ethyl Acetate
the relative polarities are given as
Methanol=0.762
Dichloromethane (methylene chloride)=0.309
Ethyl Acetate=0.228
So the numbers are given as
Methanol :1
Dichloromethane (methylene chloride):2
Ethyl Acetate:3
Reverse Phase Chromatography
In the reverse phase chromatography, the eluting power is highest for the solvent which has the lowest polarity.
So from the given solvents as diethyl ether , water and toluene
the relative polarities are given as
Diethyl ether=0.117
Water=1.0
Toluene=0.099
So the alphabets are given as
Toluene :A
Diethyl ether: B
Water:C
Answer:
This is hilarious, every time I ignite, they feed me water, little do they know this heat will defeat, and hydrogen only makes me stronger!
Explanation:
When Hg is burning, it uses the oxygen from H2O and turns it into hydrogen gas, and that contributes to the burning.
Answer:
Electrones de valencia.
Explanation:
¡Hola!
En este caso, dado en química se conocen las estructuras de Lewis como representaciones gráficas de como los elementos están enlazados entre sí, debemos tener en cuenta que estos enlaces se forman entre los electrones de valenciam, los cuales son utilizados para su representación. Se sabe que los electrones de valencia son representados con puntos alrededor del elemento a través de puntos que se unen entre sí y son el número de electrons en la capa más externa de los elementos en cuestión; por ejemplo, cloro tiene 7 electrones de valencia, azufre tiene 6, hidrogeno 1, carbono 4 y así sucesivamente.

The circulatory system is responsible for bringing food and oxygen to every cell in your body. The respiratory system is responsible for carrying oxygen and carbon dioxide in and out of your body.
Hope this helps :)
Incomplete question. The full question read;
You are analyzing water that is known to contain silver nitrate, AgNO3. You decide to determine the amount of silver nitrate using gravimetric analysis based on the reaction:
Ag+ + Cl– → AgCl
You add excess NaCl to a 100 ml sample of the water and find that 1.2 g of AgCl solid forms.
If you added excess NaCl to a 200 ml sample of water from the same source, how many grams of AgCl solid would you expect to form?
Answer:
<u>0.6 gram</u>
Explanation:
<em>Remember</em>, we were first told when NaCl is added to a 100 ml sample of the water it results in the formation of 1.2 g of AgCl.
Hence, if the volume of water is increased 2x to 200 ml from 100 ml, and NaCl is added to it, then the expected number of grams should be 0.6 (1.2g/2). That is, with increased volume, the amount of dissolution of AgCl is increased.
