iron is a metal and sulfur is a non-metal and both are in the periodic table which means they are elements. Together they can form a compound with an ionic bond. and can be mixed to form a mixture.
Answer:
A spectator ion refers to a charged atom in a chemical reaction that does not undergo a chemical change.

Answer:
The correct answer is - Orange light reflected from the t-shirt enters human eyes.
Explanation:
Human eyes and brain are altogether able to detect the color of the object by translating the light which is reflected by the object and transmitted by the light receptors in the eyes ad brain translate light to color.
The objects are able to absorb some colors and reflect others on the basis of their wavelength, The reflected colors are detected by our eyes and brain and objects appear to be a particular color. like here, the orange color is reflected by the t-shirt and enters in human eyes.
The half-reaction are:
Cd ---> Cd(OH)₂
The oxidation number of Cd changed from 0 to +2. So, the number of mol electron transferred here is 2.
NiO(OH) --> Ni(OH)₂
The oxidation number of Cd changed from +3 to +2. So, the number of mol electron transferred here is 1.
Now, the greatest common factor would be 2. So, we use n=2 for the formula for ΔG°. F is Faraday's constant equal to 96,485 J/mol e.
ΔG° = nFE° = (2)(96,485)(1.5) =<em> 289,455 J</em>
