Group 12 Elements have two valence electrons while Group 13 Elements have three valence electrons.
Number of valence electrons tend to determine factors like reactivity. So elements with different number of valence electrons will have different properties.
That is why G12 and G13 have different properties
The given reaction is
2 SO2 + O2 <=> 2 SO3, for which kp = 2 at a given temperature
Equilibrium constant = pSO3^2 / pSO2^2 X pO2
Q= (3.4)^2 / (2.2)^2 X 1.6 = 1.5
As Q< Kp
The reaction is not at equilibrium and reaction will go in forward direction
I believe that the answer is Oxygen. Hope this helps. :)
Answer:
Definition:
Titration is a quantitative technique where solution of known concentration is used to determine the concentration of unkown solution.
Explanation:
Titration is a quantitative technique where solution of known concentration is used to determine the concentration of unkown solution. it is also called titrimetry or volumetric analysis.
Titrant:
The known solution is called titrant. Titrant is prepared from the standard solution of known concentration and volume. It is added from the burette to the analyte.
Analyte:
The substance whose concentration or quantity is to be determine is called analyte. Titrant is carefully added to the analyte to carry out the reaction untill the end point is reached.
Usually the indicator are used to signal the end point.
End point:
It is also called equivalence point. it is the point where indicator shows that the amount of titrant needed to complete the reaction is added to the solution. it is indicated by colour changes during the reaction.
Procedure:
1. The burette is filled with titrant.
2. The flask is filled with the analyte.
3. One drop of indicator is added to the analyte before satrting the titration.
4. Now the titrant is added slowly into the analyte, drop wise until the indicator show the colour which indicate the end point.
5. After the end point is reached, note the burette reading.
6. At the end of titration final calculations can be done.
Types of titration:
Acid-Base titration
Redox titration
Answer:
0.54g of Cr
Explanation:
Current (I) = 10A
Time (t) = 100s
Molecular mass of Cr = 51.996 amu
Faraday's first law of electrolysis states that
The mass of the substance (m) of a given substance deposited at an electrode is directly proportional to the quantity of electricity or charge (Q) passed
m = nQ
M = mass of the substance
n = electrochemical constant
Q = charge passed through it
Q = IT
Q = (10 * 100) = 1000C
1 moles = molarmass = Faraday's constant (96500C)
Molar mass = Faraday's constant (96500C)
51.996 g = 96500C
How many grams will be liberated with 1000C
51.996g = 96500C
Xg = 1000C
X = (1000 * 51.996) / 96500
X = 51996 / 96500
X = 0.5388g = 0.54 g of Cr will be deposited
