When 0.1 M HNO₃ is added to water it dissociates as follow,
HNO₃ → H₃O⁺ + NO₃⁻
Let us calculate the pH of this acid in order to know its strength,
As,
pH = -log [H₃O⁺]
Putting H⁺ concentration value,
pH = -log [0.1]
pH = 1
It is highly acidic,
And being strong acid it completely ionizes in water producing only H₃O⁺ and NO₃⁻.
So,
The concentration of H₃O⁺ = 0.1 M
and,
The concentration of NO₃⁻ = 0.1 M
Answer : The atomic mass of chlorine is, 36.723 amu
Explanation :
Average atomic mass of an element is defined as the sum of masses of each isotope each multiplied by their natural fractional abundance.
Formula used to calculate average atomic mass follows:
As we are given that,
Mass of 35-Cl isotope = 35 amu
Percentage abundance of 35-Cl isotope = 13.85 %
Fractional abundance of 35-Cl isotope = 0.1385
Mass of 37-Cl isotope = 37 amu
Percentage abundance of 37-Cl isotope = 86.15 %
Fractional abundance of 37-Cl isotope = 0.8615
Now put all the given values in above formula, we get:
Therefore, the atomic mass of chlorine is, 36.723 amu
I think it is D free energy
Answer: It is chemical energy, which is a type of potential energy.
Explanation: Natural gas consists of mixture of hydrocarbons such as methane, butane and others which are chemical substances, thus they contain chemical energy stored in the bonds of the molecules.
Potential energy is any form of energy that has stored potential that can be used later. Examples include nuclear energy, chemical energy, etc.
Thus the type of energy present in natural gas is chemical energy, which is a type of potential energy.
