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.

the answer is true.

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !
