I think so that hypothesis is for isotopes and atomic mass.
Answer:
combustion
Explanation:
The enthalpy change for the complete burning of one mole of a substance
is the enthalpy of __combustion_____ .
Electromagnetic radiation.
1.6 X M is the [H] in a HC102 solution that has a pH of 3.78.
Explanation:
Given:
pH of the acid = 3.78
[H+] ion concentration = ?
The dissociation of the acid is shown as:
+ ⇔ HClO2
however, weak acid like HClO2 does not dissociate or ionize completely which causes low hydrogen ion release in the solution.
pH is calculated by applying the formula:
pH = - log [H+]
To calculate the H+ ion concentration the equation will be expressed as:
[H+] =
=
= 1.6 X M
The concentration or molarity of the Hydrogen ion in the solution of the acid is 1.6 X M.
