Answer:
Pure Water
Explanation:
The common ion effect describes the effect on equilibrium that occurs when a common ion (an ion that is already contained in the solution) is added to a solution. The common ion effect generally decreases solubility of a solute(Khan Academy).
NaCl, AgNO3, KCl, BaCl2 solutions all have a common ion with AgCl. As a result of this, AgCl will be much less soluble in these solvents than it is in pure water.
Therefore, AgCl will have the highest solubility in pure water compared to all the solutions listed above.
The statement "According to Le Châtelier's principle, an increase in temperature will shift the equilibrium position toward the products in an endothermic reaction" is definitely true.
<h3>What is Le Châtelier's principle?</h3>
Le Châtelier's principle may be defined as transformations in the temperature, pressure, volume, or concentration of a system that will lead to observable and conflicting changes in the strategy in order to accomplish a refreshed equilibrium state.
According to Le Châtelier's principle, an increase in temperature generates the equilibrium to move in the direction of the product of the endothermic reaction, and the decrease in the temperature rationales the equilibrium to move in the direction of the product of the exothermic reaction.
Therefore, it is well described above.

Answer:cotton
Explanation: cotton absorbs sweat and heat . the sweat is evaporated and thus it cools the body . so cotton is best for summer
Answer:
The nucleon number of given atom = 51
Explanation:
An atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.
All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other. For example if neutral atom has 6 protons than it must have 6 electrons. The sum of neutrons and protons is the mass number of an atom while the number of protons are number of electrons is the atomic number of an atom.
The mass number is also called nucleon number.
The nucleon number of given atom = number of protons + number of neutrons
The nucleon number of given atom = 25 + 26
The nucleon number of given atom = 51
Answer:
C) 2H2SO4(aq)+ 2Ba(OH)2(aq)---->2BaSO4(s)+4H2O(I)
Explanation:
The reaction proper:
2H₂SO₄ + 2Ba(OH)₂ → 2BaSO₄ + 4H₂O
The above reactions is a typical acid-base neutralization reaction.
A reaction in which oxidation-reduction did not take place is called a non-redox reaction. In such a reaction, there is no transfer of electrons between reactants, that is, none of the atoms of the reactants changes its oxidation number in forming the products.
Most neutralization reactions are non-redox reactions.
