BaSO₄(s) ⇄ Ba²⁺(aq) + SO₄²⁻(aq)
Ksp=[Ba²⁺][SO₄²⁻]
[Ba²⁺]=[SO₄²⁻]
Ksp=[Ba²⁺]²
Ksp=(1.76*10⁻³)² =3.0976×10⁻⁶ ≈3.1×10⁻⁶
Answer:
2.37x10⁻⁷ M⁻².s⁻¹
Explanation:
For a generic reversible reaction:
A + B ⇄ C + D
Kf is the constant of the formation of the products (C and D), Kr is the constant of the formation of the reactants (A and B), and Kc is the general equilibrium constant, which is:
Kc = Kf/Kr
2.76x10³ = 6.54x10⁻⁴/Kr
Kr = 6.54x10⁻⁴/2.76x10³
Kr = 2.37x10⁻⁷ M⁻².s⁻¹
Answer:
Hence the correct option is an option (b) Sr4, Cl,Br−,Na+.
Explanation:
Bromine and chlorine belong to an equivalent group. As we go down the group the dimensions increases which too there's a charge on the bromine atom. therefore the size of the Br- is going to be larger in comparison to the chlorine atom.
Sr atom is within the second group, and also it's below the above-mentioned atoms.so Sr is going to be the larger one among all the atoms.
Sodium and chlorine belong to an equivalent period .size decrease from left to right. but due to the charge on sodium its size decreases and there's an opportunity that Na+ size could be adequate for Cl.
Here we finally assume that two atoms are of an equivalent size (Na+ and Cl) which are less in size compared to the opposite two(Sr and Br-) during which one is greater (Sr)and the opposite is smaller(Br-).
Answer: The suffixes of the names of polyatomic ions have a pattern associated with them. ... For example, the sulfite ion has three oxygen atoms whereas the sulfate ion has four oxygen atoms.
Answer: both the different glycosidic linkages of the molecules and the different hydrogen bonding partners of the individual chains.
Explanation:
Glycogen is a polysaccharide of glucose which is a form of energy storage in fungi, bacteria and animals. Glycogen is primarily stored in the liver cells and skeletal muscle.
The difference in interchain stability between the polysaccharides glycogen and cellulose is due to the different glycosidic linkages of the molecules and the different hydrogen bonding partners of the individual chains.
