Answer:
The calculated concentration of HCl will be less than actual.
Explanation:
Suppose during titration, the <em>HCl</em> was taken in burette and the <em>NaOH</em> in the volumetric flask.
Now we will use equivalence formula for the calculation of concentration of HCl.
Where L.H.S is for hydrochloric acid and R.H.S is for sodium hydroxide. The terms N and V represent normality and volume respectively.
If we calculate for
We see that if the volume of the HCl is greater then the concentration of the HCl will be reduced.
Answer:
Oxygen
Explanation:
<em>Oxygen. </em>Based on octet rule (An empirical rule that refers to the tendency of atoms to prefer to have eight electrons in the valence shell giving the same electronic configuration of a noble gas), the Sulfur and oxygen need two electrons to complete eight electrons in its valence shell, giving, in this way, the same electronic configuration as Ne and Ar, respectively.

Nuclear binding energy is the energy that would be required to disassemble the nucleus of an atom into its component parts. These component parts are netrons and protons, which are collectively called nucleons
<h3>Answer:</h3>
Ionic Bond
<h3>Explanation:</h3>
Types of Bonds can be predicted by calculating the difference in electronegativity.
If, Electronegativity difference is,
Less than 0.4 then it is Non Polar Covalent Bonding
Between 0.4 and 1.7 then it is Polar Covalent Bonding
Greater than 1.7 then it is Ionic Bonding
For Mg and Cl,
E.N of Chlorine = 3.16
E.N of Magnesium = 1.31
________
E.N Difference 1.85 (Ionic Bond)
<h3>Conclusion:</h3>
MgCl₂ being ionic in nature when dissolved in water dissociates into Magnesium and Chloride ions respectively.
