<h2>Answer :</h2>

The blackened spots on the spoons are nothing but silver sulfide . Silver sulfide is formed when silver comes in contact with moisture , vapour or sulphur . Since , they have said that some black spots could be seen , we can be sure that the silver has rusted from sulphur as only silver and sulphur can form silver sulfide , which is black in colour . Since there has been a change in the chemical composition of the sliver in the silver spoon ( silver into silver sulfide by sulphur ) we can say that the change that occurred here is a chemical change . Therefore , the dull black spots on the silver spoon are the results of a <em>chemical</em><em> </em><em>change</em><em> </em> .
