What is the difference between a “weak acid” and a “strong acid”? (i.e. if you have a 1 M solution of a weak acid and a 1 M solution of a strong acid, will they each contain the same number of removable hydrogen ions?)
Class, What is the difference between a data entity (data model) and an external entity (process model)? Tables are made up of rows and columns. What do the rows represent? What do the columns represent? What is the difference between the logical ERD and the physical ERD? How can you translate entities from the CDFD? (Analyze the data flows.)

What is the difference between H3PO4 and HCIO4? O HCIO, is a strong acid, whereas H3PO4 is a weak acid. None of the above statements are correct about the difference between H3PO4 and HCIO4. H3PO4 is a strong electrolyte, whereas HCIOis a nonelectrolyte. OH3PO4 is a monoprotic acid, whereas HCIO, is a polyprotic acid. OH3PO4 is an acid, whereas HCIO4 is a base.
