Answer : The value of for the given reaction is, 0.36
Explanation :
Equilibrium constant : It is defined as the equilibrium constant. It is defined as the ratio of concentration of products to the concentration of reactants.
The equilibrium expression for the reaction is determined by multiplying the concentrations of products and divided by the concentrations of the reactants and each concentration is raised to the power that is equal to the coefficient in the balanced reaction.
As we know that the concentrations of pure solids and liquids are constant that is they do not change. Thus, they are not included in the equilibrium expression.
The given equilibrium reaction is,
The expression of will be,
First we have to calculate the concentration of .
Now we have to calculate the value of for the given reaction.
Therefore, the value of for the given reaction is, 0.36
Answer:
The answer is A, if im not mistaken
Answer:
there are eight electrons
Answer:
The correct answer is - option 1. the molarity of H changes by one order of magnitude.
Explanation:
pH is dependent on the concentration of H+ not on the volume of H+ or the salt content. The molarity of H+ changes by one order of magnitude with the change in pH of 1.0 unit that can be an increase or decrease in molar concentration by one order of magnitude or factor of 10.
Order of magnitude refers to the factor of ten or powers of ten. A change in the order is equal to the change of the exponent changes by ± 1
For a hydrogen atom, composed of an orbiting electron bound to a nucleus of one proton, an ionization energy of 2.18 × 10−18 joule (13.6 electron volts) is required to force the electron from its lowest energy level entirely out of the atom.
