What is nickel and dimes in a box mixture or pure substance?
mixture. nickel and dimes are made of different elements. If they were melted together, at a chemical scale and bonded, they would be a compound. As they are mixed together, but not bonded, they are a mixture. And dont forget the air in the box too, that adds to the mixture.
