Hello!
DescriptionA scientific theory is an explanation of an aspect of the natural world that can be repeatedly tested and verified in accordance with the scientific method, using accepted protocols of observation, measurement, and evaluation of results. Where possible, theories are tested under controlled conditions in an experiment.
Answer:
33 Neutrons
Explanation:
Atomic Mass = # of Protons + # of Neutrons
Atomic Number = Proton count
Atomic Mass of Co = 27 Protons + x Neutrons
60 = 27 + x
x = 33
H3PO4 + H2O <--> H3O+ + H2PO4- Ka1= ([H3O+][H2PO4-])/[H3PO4])
H2PO4- + H2O <--> H3O+ + HPO4^2- Ka2= ([H3O+][HPO4^2-])/[H2PO4-])
HPO4^2- + H2O <--> H3O+ PO4^3- Ka3= ([H3O+][PO4^3-])/[HPO4^2-])
Ka1 >> Ka2 = almost all the H3O+ is formed in the first step.
Ka3 will only happen under very basic conditions.
If you wanted to measure x-rays you would have to place your sensor in deep space where there would be no interferece.
