Question

Which of the substances Na3PO4, CBr4, rubber, Au, and 
quartz best fits each of the following descriptions? 
(a) Amorphous solid 
(b) Ionic solid 
(c) Molecular solid 
(d) Covalent network solid 
(e) Metallic solid

Accepted Answer

Hey everyone, we're asked to match the solids. PVC, nickel, calcium, sulfate, sucrose and diamond to their correct classifications. First, let's go ahead and write out our descriptions for each of these solids. So we know that PVC is a polyvinyl chloride. So we know that PVC stands for polyvinyl chloride and this is going to be a polymer. So looking at our answer choices, this would be an amorphous solid. So four is going to be PVC. Now let's go ahead and describe nickel. Now we know that nickel is a metallic solid. So this matches our answer choice too. Next looking at our calcium sulfate, we know that this is made up of ions which are our calcium with a plus two charge and are sulfate. Wouldn't when we know that this is made up of ions which is going to be our calcium with a plus two charge plus our sulfate, which is one of our poly atomic ions. So this is going to be an ionic solid which matches answer choice five. Now let's go ahead and look at Sue Gross for sucrose, we know that this is table sugar and this is held by inner molecular forces. So this matches answer choice one being a molecular solid. And lastly looking at our diamond, we know that this has a Covalin network of carbons. So this matches answer choice three, which states covalin network solid. And these are going to be our final answers for this question. Now I hope that made sense. And let us know if you have any questions
