1. A teacher instructs her students to measure out 50.0 mL of hydrogen peroxide for three trials of an experiment. A student measures out 37.2 ml, 38.7 mL, and 36.9 mL. Use this information to answer the questions below (1a and 1b). 1a

Calculate the percent error for each measurement and include them below. (For example: 1%, 2%, 3%)

True, the standard unit for volume is liters which can be represented by either a lower case "l" or a capital "l"

It is a mixture. simply put, a compound must be pure, that is, of only one chemical structure and composition. a mixture is made of different chemical substances (i.e. elements, molecules, compounds) that are not chemically bonded to each other, but instead physically grouped together, as in the case of gasoline (a homogeneous solution).

Answer    "a salt" would be the best answerexplanationsalts can be defined as ionic compounds that are neither acids nor bases. nacl is an example of a salt, and its ionic.an enzyme is an organic compound which is covalently bonded, not ionically bonded.acids are generally held together by covalent bondsan element does not need any bonds to exist
