The equivalence point is the point in a titration where the amount of titrant added is enough to completely neutralize the analyte solution. The moles of titrant (standard solution) equal the moles of the solution with unknown concentration. ... The equivalence point is not the same as the endpoint of a titration.
Answer: An existing theory is modified so that it can explain both the old and new observations.
Explanation:
Answer: There are four atoms
Explanation: mass of Cl atom is 35.45 amu
Amount of atoms n = m/M = 142 / 35.45 = 4
Answer:
I think you may have chosen the wrong subject for your question, besides where is the context to this?
Answer:
a. The number of neutrons in the nucleus
Explanation:
Having more protons or electrons would change the charge of the atom making it an ion. Neutrons have no charge so the overall charge of the atom is not affected; neutrons also have a relative mass of 1 which is why there are different isotopes.
Hope this helps!
