Answer : The molar solubility of in pure water is, 0.0118 M
Explanation : Given,
The solubility equilibrium reaction will be:
Let the molar solubility be 's'.
The expression for solubility constant for this reaction will be,
Now put all the given values in the above expression, we get:
Therefore, the molar solubility of in pure water is, 0.0118 M
<em>Answer</em><em>:</em>
Virtual images are always formed by convex mirrors and are formed by concave mirrors when the object is placed in front of F.
Explanation:
A concave mirror will only produce an upright image if the object is located in front of the focal Point.
Hope this helped. :)
Answer:
V₂ = 1326.62 L
Explanation:
Given that,
Initial volume, V₁ = 1800 L
Initial temperature, T₁ = 35°C = 308 K
Final temperature, T₂ = -46°C = 227 K
We need to find the final volume of the blimp. The relation between volume and temperature is given by :
So, the final volume of the blimp is 1326.62 L.
The element that will have the lowest electronegativity is an element with a small number of valence electrons and a large atomic radius.
Electronegativity of an element is the ability or power of that element in a molecule to attract electrons to its Valence electrons. The following are the properties of electronegativity:
- It increases across a period from left to right of the periodic table,
- It decreases down the periodic table groups
- Group 1 elements are the least (lowest) electronegative elements. These elements have the lowest valence electrons with a large atomic radius.
- Group 7 elements are the most electronegative elements.
Atomic radius of elements increase down a group because of a progressive increase in the number of shells occupied by electrons which increases the size. But it decreases across a period because electrons are accommodated within the same shell leading to greater attraction by the protons in the nucleus.

Answer:
Polarity is a property of molecules that represents the separation of electrical charges within the molecule, depending on the number and type of bonds it possesses.
The covalent bond between two atoms can be polar or apolar. This depends on the type of atoms that make it up: if the atoms are equal, the bond will be apolar (since no atom attracts electrons more strongly). But, if the atoms are different, the bond will be polarized towards the most electronegative atom, since it will be the one that attracts the electron pair with more force.
For each of the followings covalent bonds the direction of polarity is the one shown in the picture.
We see that in the C-O bond oxygen is more electronegative than carbon. Therefore, there will be a dipole vector oriented towards of the oxygen. We can represent this polarization of the bond by means of an arrow, which always points to the most electronegative atom.
Explanation:
The polarity of a chemical bond occurs when there is an asymmetric distribution of the electronic cloud of the bond around the two atoms that make up that link. This happens when both atoms have different electronegativity.
- Each bond composed of different atoms generates a dipole vector, which points to the most electronegative atom.
- A molecule will have as many vectors as it has covalent bonds.
- If the vectors do not cancel out, then the molecule will be polar.
