Answer:
Kindly check the explanation section.
Explanation:
When the Arsenic acid,H3AsO4 is put in water it dissociates to form or give out 1 proton, 2 protons or 3 protons that is 1H^+, 2H^+ and 3H^+. Check the equation showing the dissociation reactions as given below;
H3AsO4 ===========> H^+ + AsO4^-
H3AsO4 ===========> 2H^+ + AsO4^2-
H3AsO4 ===========> 3H^+ + AsO4^3-
Therefore, the total charge balance is given as:
[H^+] =[OH^-] + [ AsO4^-] + 2[ AsO4^2-] + 3[ AsO4^3-].
Kindly note that the [OH^-] is from water.
Building a tower out of magnetic blocks and water vapor condensing on a bathroom mirror are only physical changes.
A physical change is easily reversible. It does not involve a change in the composition of a substance.
A tower built out of magnetic blocks can easily be pulled apart and water that condensed on a bathroom mirror can easily change back to vapour by heating.
All these are possible because the both processes are only physical changes.
