Asolution is known to contain an inorganic salt of one of the following elements. the solution is colorless. the solution contains a salt of

E) Zn

Explanation:

The inorganic salts are ionic compounds formed by a metal and a nonmetal element. They are solid at ambient conditions, may conduce electricity when are in an aqueous or liquid phase, and they can have color or not.

The color of the salts its a characteristic of the metal element. During the ionic bond, the electron of the metal will be excited to exit the atom, thus, energy in the form of light will be displaced. Is this way the fireworks are done, for example.

Cu has a blue light, Mn has white light, Fe has brown or yellow lights, Ni is blue, and Zn is colorless.

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
