Molar solubility of AgCl will be 0.59 ×
M.
The amount of a chemical that can dissolve in one liter of a solution before reaching saturation is known as its molar solubility. This implies that the quantity of a substance it can disintegrate in a solution even before the solution becomes saturated with that particular substance is determined by its molar solubility.
A compound's molar solubility would be the measure of how many moles of such a compound must dissolve to produce one liter of saturated solution. The molar solubility unit will be mol L-1.
Calculation of molar solubility:
Given data:
M = 0.30 M
= 1.77 × ![10^{-10}](https://tex.z-dn.net/?f=10%5E%7B-10%7D)
The reaction can be written as:
AgCl ⇔ ![Ag^{+} + Cl^{-}](https://tex.z-dn.net/?f=Ag%5E%7B%2B%7D%20%2B%20Cl%5E%7B-%7D)
s s (s+0.30)
= [
]+ [
]
1.77 ×
= s (0.30)
s = 1.77 ×
/ 0.3
s = 0.59 ×
M
Therefore, molar solubility of AgCl will be 0.59 ×
M.

<u>Answer:</u> The correct answer is Option B.
<u>Explanation:</u>
Chemical reactivity is defined as the tendency of an element to loose of gain electrons.
Non-metals are the elements which gains electrons and hence, their chemical reactivity will be the tendency to loose electrons.
Their chemical reactivity increases as we move from left to right in a period because the valence shell come closer to nucleus as we move from left to right. So, addition of new electron in the valence shell becomes easier due to greater attraction between nucleus and valence electron.
For the given options:
<u>Option A:</u> Silicon
This element lies in Group 14 and Period 3.
<u>Option B:</u> Chlorine
This element lies in Group 17 and Period 3.
<u>Option C:</u> Sulfur
This element lies in Group 16 and Period 3.
<u>Option D:</u> Phosphorus
This element lies in Group 15 and Period 3.
Hence, chlorine will readily accept electrons due to its position in the periodic table.
Answer:
1.) To convert between grams and moles, you would use the substance's molar mass. To go from grams to moles, divide the grams by the molar mass. 600 g58.443 g/mol = 10.27 mol of NaCl. It has been found that 1 mol of any gas at STP (Standard Temperature and Pressure = 0 °C and 1 atm) occupies 22.4 L
Answer:
The correct answer is B
Explanation:
This question seeks to test the difference between mass and weight.
Mass is a measurement of the amount of matter present in an object. While <u><em>weight is a measurement of the force of gravity pulling (the mass of) an object</em></u>. Hence, measuring the weight of the moon rocks in the moon might be a waste since the weight of the object on earth will produce a different value due to the difference in the force of gravity between the earth and the moon.
1 mole= 602,200,000,000,000,000,000,000 its just this huge number! =6.022 x 10 to the power of 23. So that's it I guess!
