Two things
Ferrous Ammonium Sulfate is a pale green or blue-green powder or sand-like solid. It is used in photography, analytical chemistry, and Iron-plating baths.
An FAS-DPD titration is as simple as a test for total alkalinity or calcium hardness. A buffered DPD indicator powder is added to a water sample and reacts with chlorine to produce the pink color characteristic of the standard DPD test.

Protons are one of the fully stable parts of matter
Answer:
Chadwick-he discovered the neutron. He discovered this by demonstrating a neutral particle with a mass the same as a proton through a reaction between gramma Ray's and a wax sample.
Rutherford-he discovered the concept of radioactive half-life, the radioactive element radon, and named alpha and beta radiation.
j.j.Thompson discovered that atoms where made up of smaller components. This had major effects for the field of physics.
:)
Atoms have positive charges? or nuclei? Rutherford conducted the infamous gold foil experiment from which he concluded an atom mist contain a dense positively charged part with a orbiting shell of negative parts. That model was refined many times to form the current model of the atom.
Answer:
Gas
Explanation:
Molecules in the solid phase have the least amount of energy, while gas particles have the greatest amount of energy. The temperature of a substance is a measure of the average kinetic energy of the particles.
