Answer:
Light energy can be converted into heat energy. A black object absorbs all wavelengths of light and converts them into heat, so the object gets warm. A white object reflects all wavelengths of light, so the light is not converted into heat and the temperature of the object does not increase noticeably.
Answer:
NaCl.
Explanation:
In the solution, ZnSe ionizes to and . Following reaction represents the ionization of ZnSe in solution -
⇄
As we want to increase the solubility of ZnSe, we must decrease the concentration of dissociated ions so that the reaction continues to forward direction.
If we add NaCl to this solution, then we have and in the solution which will be formed by the ionization of NaCl.
Now, in the solution will react with two ions to form as follows -
⇄
Due to this reaction the concentration of will decrease in the solution and more ZnSe can be soluble in the solution.
