Explanation / Answer

ANS 1. the copper do not looklike as our solid copper since in solid sample some copper must got oxidised and it should be greyish while this newly regenerated copper is extreamly pure and shiny otherwise the property would be same as solid copper.

ANS 2. Percent recovery = amount of substance you actually collected / amount of substance you were supposed to collect * 100 . Uing this formula we can calculare percentage recovery easily sing values are not mentioned in question so very sorry for calculations.

ANS 3. Percent loss =100-Percent recovery

there might be some loss sue to some error. since no any process can be 100 percent efficeint.

ANS 4. Loss may be happen while collectiom of solid from filter papper. there may be chance that some supper got sticked with it and not not transferred totally.
