Answer:
Chemistry, the science that deals with the properties, composition, and structure of substances (defined as elements and compounds), the transformations they undergo, and the energy that is released or absorbed during these processes
Electron affinity is the change in energy of an atom with a neutral charge when an electron is added to form an anion. A more negative electron affinity corresponds to a greater attraction for an electron. Electron affinity become less negative down a group and from left to right in the periodic table.The correct answer would be the large nonmetal atoms. Large nonmetals have a higher electron affinity than metals, meaning they are more likely to gain electrons than atoms with a lower electron affinity.
Cooling a substance causes molecules to slow down and get slightly closer together, occupying a smaller volume that results in an increase in density. ... Cold water is more dense and will sink in room-temperature water.
I think it is decomposition because it processes in which chemical species break up into simpler parts.
I think its Na3(PO4)+Cu(SO4) --> Na2(SO4) + Cu3(2PO4). Hope am right
